Minimize Controllable Feedwater Heater Losses Through Heat Rate Awareness


A feedwater heater is a device used in a power plant to pre-heat water being delivered to a steam generating boiler. Preheating the feedwater prior to steam generation improves the thermodynamic efficiency of the system. Heat rate is a measure of how efficiently a power plant uses heat energy. You can measure heat rate by the number of BTUs the power plant requires to generate a kilowatt hour of energy. As your heat rate goes up, so do your fuel costs. Considering fuel expenditures account for 70 to 80 percent of production costs and millions of dollars per year, improving heat rate one percent could generate five hundred thousand dollars in annual savings for a 500 megawatt power plant.

To contain fuel costs, power plants must maximize the efficiency of their feedwater heaters. That's why many companies today are focusing on improving heat rate as a way to use their feedwater heaters more effectively and significantly reduce their fuel costs.

The video above (courtesy of Magnetrol) explains ways to focus on heat rate awareness to minimize controllable losses from the feedwater system.

Plating Application: Chromic Acid Tank Level

Plating acid tanks
Plating acid tanks.
Chromium is widely used in the metal finishing industry for both decorative and hard-chrome plating. The chemicals used in Chrome plating are very harsh and corrosive. Chromium plating requires that the metal to be plated to be pretreated in a sodium cyanide/caustic soda bath and then plated in a chromic acid bath.

A large international plating company located in the USA needed a cost effective liquid level switching that would perform flawlessly on their chemical plating baths.

Problem
Tank level
The chemicals used in plating, specifically Chromic Acid, are extremely corrosive. Many times these chemicals need to be kept at elevated temperatures, resulting in corrosive vapors. Controls installed in and around areas where vapors are present are adversely affected.  For this customer, the tank level instruments near the chromic acid tanks were the most problematic.

Solution

Levelpro PLF
Levelpro PLF
Icon Process Controls, a manufacturer specializing in corrosion resistant fluid handling instrumentation, recommended their Levelpro PLF series plastic level switch. The Levelpro PLF provides excellent chemical resistance. Body materials are available in PVC, PP, PVDF, or 316SS. The level switch is available is sizes from 6" to 10 feet, with up to 8 different switch points, and unlike ultrasonic sensors, the PLF Series are not affected by foam, vapor, or turbulence. Additionally, they require no power and are available in N/O or N/C switch positions.

The PLF series can be used to indicate high and low levels, notification of upset conditions or turn pumps or valves on-off. They are also an excellent choice for redundant high| low level indication when used in conjunction with a continuous level sensor.

Coriolis Flow Meter Improves Fuel Oil Control and Efficiency at Power Plant

TRICOR’s TCM-28K
A power plant installed variable area flow meters for fuel oil feed control.  The variable area flow meters proved too unreliable to detect clogging in the burner system. The result was inefficient, unbalanced flow measurement resulting in very low burner efficiency, frequent downtime due to clogging, and heavy maintenance requirements.

The process medium was burner fuel oil at temperatures between 50 F to 210 F, with flow varying between 7 to 55 lbs/hr.

The solution was installing TRICOR’s TCM-28K Coriolis flow meter. The TCM 028K Coriolis Mass Flow Meter has a maximum mass flow rate of 28,000 kg/hr (1029 lb/min) or 4227 bbl/day and nominal size of DN25 (1”), and is rated for process pressures up to 100 bar (1450 psi). Standard accuracy for the TCM 028K is 0.3%, but with a custom calibration, 0.1% accuracy is possible. These meters have good overall accuracy, zero stability, and pressure drop. The simple self-draining U-shape tube design provides for easy cleaning/flushing.

After installation, all mentioned problems disappeared. Moreover, with the flexibility of TRICOR installation length, TRICOR was able help the customer in this challenging application to avoid extra installation costs.

ADVANTAGES:
  • Increased burner availability
  • Less downtime
  • More efficient burner management 
  • Reduced maintenance costs Increased productivity

Custom Sanitary Coriolis Flow Meter Makes Better Mayonnaise

Coriolis Flow Meter for Mayonnaise
A large scale producer of condiments for the restaurant industry needed a better way to control the mixture of several ingredients in the production of mayonnaise. The ingredients needed to be mixed at exact ratios to produce a consistent product. The customer wanted to automated the process to remove human error from the mixing of these blends. Products to be measured are starch, an egg blend, and the final product of mayonnaise.

All the ingredient measurements must be made by sanitary instruments because this is an FDA regulated food application. Measurements must also be maintained at relatively low system pressures. This is difficult due to the viscous nature of the product. Because both starch and mayonnaise are shear thinning materials, precise viscosity data is not available, therefore engineering observation of the process was necessary to identify the proper size Coriolis meters.

Level Instrumentation for Steam Generation

Level Instrumentation for Steam Generation

Steam is today’s utility player in the industrial energy arena. It cleans and sterilizes, dries and concentrates, separates and evaporates. In cookery, it preserves flavor, texture, and retains nutrients. In chemistry, it fosters reactions by controlling process pressure and temperature. In biotechnology, it’s essential for growing production organisms. Steam ranges in purity from boiler grade for routine tasks, to culinary grade “Clean Steam” for food and dairy, and graduates up to super pure, pyrogen-free steam for biopharmaceutical use.

Magnetrol, a world-leading manufacturer of level and flow instrumentation, has assembled an excellent application summary for the use of level instrumentation in steam generation.

How They Work: Magnetically Coupled Liquid Level Indicators (Mag Gauges)


Magnetically coupled liquid level indicators are in widespread use throughout today's process industries.

Originally designed as an alternative to site and gage glass devices, MLI’s are now commonly utilized in both new construction and plant expansions. Orion Instruments magnetic level indicators are precision engineered and manufactured to indicate liquid level accurately, reliably, and continuously.

As shown in this video, a float designed for the specific gravity of the process liquid travels inside the MLI chamber tracking the rise and fall of the process media.

This float contains an internal magnetic assembly that couples with the external visual indicator. The individual “flags” or “flippers” rotate 180 degrees as the level rises and falls, indicating the position of the liquid inside the MLI, and therefore, indicating the level of the liquid in the vessel.

These units are completely sealed and require little to no periodic maintenance. MLI’s also eliminate fugitive emission and glass breakage concerns common with site and gage glasses.

To complement these products, level switches and transmitters are available to further expand the control and alarm capability of the MLI.

Industrial Pressure and Temperature Switch Operating Basics

pressure switch
Internal view of pressure switch.
(Ashcroft)
A pressure switch is a mechanical device that detects the presence of fluid (gas or liquid) pressure. Pressure switches use a variety of sensing elements to convert pressure changes to linear movement. These sensors are known as diaphragms, bellows, bourdon tubes, and pistons. The movement of these sensors, caused by pressure fluctuation, is transferred linearly through a rod or piston to a set of electrical contacts to open or close a circuit.

The opening and closing of the electrical circuit is done through electrical contacts. These electrical contacts are most often enclosed in their own housing in an assembly known as a microswitch. These contacts in the pressure switch are associated with the terms "normal", as in "normally open" or "normally closed". The normal status of a switch is the resting state with stimulation. A pressure switch will be in its normal status when it senses low or minimum pressure. For a pressure switch, normal status is any fluid pressure below the trip threshold of the switch.

Switch Symbols
Switch Status Symbols
Some of the earliest and most common designs of pressure switch was combining the bourdon tube pressure sensor with mercury switch. A bourdon tube is basically a curved tube that flexes straight when pressure is applied. The bourdon tube's flex is amplified through gearing and made significant enough to tilt the glass bulb of the mercury switch so that the mercury flows over the electrical contacts, thus completing the circuit.  Many of these pressure switches were sold on steam boilers. While they became a de facto standard, they were sensitive to vibration and breakage of the mercury bulb and resulting mercury contamination.

Explosion proof pressure switch
Explosion proof pressure switch.
(Ashcroft)
Another common design feature pressure switches use is referred to as force-balanced pressure sensors.  This design operates by countering the force provided by the pressure-sensing element with a mechanical spring. The system remains static until the pressure-vs-spring balance is overcome. Once the sensor pressure exceeds the spring tension, movement occurs and the electrical switch state is changed. In this design, the tension on the spring may be adjusted to set the tripping point, thus providing an adjustable setpoint.

Deadband or (reset pressure differential) is one of the most important application considerations when applying a pressure switch. This setting determines the amount of pressure change required to reset the switch to its normal state after it has tripped.  The differential pressure of a pressure switch should not to be confused with differential pressure switch, which actually measures the difference in pressure between two separate pressure ports.

Temperature switch
Temperature switch
(Ashcroft)
Temperature switches operate on exactly the same principle, but use the concept of thermal expansion, instead of direct pressure sensing, to create the the movement required to change the electrical contact status. In the enclosed thermal sensor (referred to as the bulb, or bulb and capillary), the liquid enclosed in the system expands and contracts in relation to temperature change. That expansion and contraction is then converted to linear movement,  and then used to open and close an electrical circuit.

There are many, very important details that need to be considered when selecting and applying pressure and temperature switches. You must consider the electrical requirements (volts, amps, AC or DC), the area classification (hazardous, non-hazardous, general purpose, water-tight), pressure sensing range, temperature range, and material compatibility. It's highly recommended you consult with a process instrumentation expert for assistance.

Level Sensors for Corrosive Liquids

Levelpro plastic level sensors
ICON Levelpro plastic level sensors.
Corrosive liquids can be found in just about every industry; food, metal finishing, water-waste water treatment, textile, automotive, to name just a few.  When it comes to selecting the correct sensor technology there are many different factors to consider.

Plastic level sensors are an excellent choice for corrosive liquid chemical applications.  Plastics, unlike metals, do not corrode; however, they can deteriorate and swell if the correct plastic is not used.

ICON Process Controls offers its Levelpro plastic level sensors for continuous level indication, as well as plastic level switches for point level notification.  There are many different factors to consider when selecting the right product for the application.

  • Chemical Liquid?
  • Concentration?
  • Temperature?

With this information a material of construction for the level sensor can be selected.  Next, it is important to understand other factors that contribute to the success or failure of the level sensor.

  • Is there particulate with the liquid?
  • Does the liquid create a film, or does it have a coating effect?
  • Does the chemical produce foam?
  • Is there sludge at the bottom of the tank?
  • Is the liquid agitated?

Once the information pertaining to the chemical and the type of sensor technology (continuous or point) is determined, ICON can recommend the most suitable product for the application.

An excellent level sensor for corrosive liquids is the 100 Series submersible level sensor.  The plastic level transmitter is available in PVC, PP and PVDF bodies, and comes standard with a corrosion-resistant PTFE jacketed cable and Kalrez O-rings.  The 100 Series submersible level sensors incorporate a weighted body which ensures the sensor sits at the bottom of the tank.  The plastic level transmitter has a ceramic sensing diaphragm that measures the head pressure of the liquid.  These level sensors are not affected by foam, vapor, condensate or turbulence, making them an excellent choice for many different applications.

If the chemical produces sludge then ICON would recommend a non-contact level technology such as the Ultrapro ultrasonic level sensor, or the Proscan radar transmitter.

For clean liquids the CFL Series continuous float is a reliable and economical choice.

ICON also offers a complete line of plastic level switches for point level indication.  These plastic switches are available in PVC, PP and PVDF materials, and the relay can be set to normally open or normally closed positions. Visit M.S. Jacobs at https://msjacobs.com for more information.

WIKA Phases Out PSD-30 and PSD-31 Pressure Switches, Replaced with PSD-4 Pressure Switch

PSD-4 Pressure Switch
The WIKA PSD-30 and PSD-31 pressure switches are currently being phased out, to be replaced with the newly updated PSD-4 pressure switch.

The model PSD-4 pressure switch represents the extensive development of the  PSD-30 pressure switch.  A high accuracy of 0.5 %, freely configurable output signals (PNP/NPN, 4-20 mA / 0-10 V), the 5:1 scalability of the analog output, in addition to outstanding self-diagnostics, make the PSD-4 an excellent automation solution for industrial machines, hydraulic systems, and pneumatic systems applications.

While the PSD-4 offers new features and functionality, pricing is comparable to that of the PSD-30 and PSD-31.  This new pressure transmitter offers customizable features, such as allowing the user to select the switch type and output signal, while offering a 5:1 turndown ratio.  Additionally, this transmitter is an economical solution for applications requiring local display with an analog output signal.  The PSD-4 provides an upgrade in quality and customizability without negatively affecting budgets.

During development of the WIKA switch family a high value was placed on a robust design and the selection of appropriate materials suited to machine-building applications.  For this reason the case and the threaded connection of the electrical connector are made from stainless steel.
