Float and Thermostatic Steam Traps

Steam traps are found on almost every steam system in commercial and industrial sites. The trap is a self-contained automatic valve that allows condensate to drain from a steam containing system, while retaining the steam within the system. Non-condensible gases can also be removed by a steam trap with a thermostatically controlled port.

Steam based heating relies on the delivery of the latent heat of the steam to a heat exchanger or piece of utilization equipment. Once the latent heat is delivered, condensate (basically hot water) forms. The condensate contains no latent heat and provides comparatively little value as a heat source. Utilization equipment and heat exchangers have their performance predicated upon a supply of steam, not hot water. A properly selected steam trap will remove condensate across a range of steam utilization rates, keeping the system operating at the rated capacity.

The steam trap routes the condensate out of the steam containing portion of the system, often on a return trip to the boiler. Cycling the condensate back through the system for re-boiling contributes greatly to steam system energy efficiency. Condensate removal is accomplished with a float. Non-condensible gases are vented through a thermostatically controlled port on the unit.

White Paper - Industrial Control System Cybersecurity Primer

Industrial control system cybersecurity is a global issue

The International Society of Automation is offering a free white paper entitled “What Executives Need to Know About Industrial Control Systems Cybersecurity”. The article provides useful commentary and information that establishes the scope of cybersecurity in the industrial process control space and provides a basic framework for understanding how every process may be impacted by lax cybersecurity efforts. The author, Joseph Weiss, differentiates Industrial Control System (ICS) cybersecurity from that of organizational IT through a review of various attributes common to both types, including message confidentiality, integrity, time criticality, and more. Any reader’s awareness and understanding of the cybersecurity risks to their operation will be enhanced through this article. I finished reading the article wanting more on the subject, and ISA is certainly a resource for additional content.

A quote from the article...

“Cyber incidents have been defined by the US National Institute of Standards and Technology (NIST) as occurrences that jeopardize the confidentiality, integrity, or availability (CIA) of an information system.”

ICS cybersecurity extends beyond preventing malicious outside intruders from gaining access. It is an important part of maintaining the overall operating integrity of industrial processes. A holistic approach is advocated to identify physical risk factors to the process and its componentry (post on device protection), as well as vulnerabilities that may prevent exploitation by unauthorized parties. Weiss goes on to describe the role and qualifications of the ICS Cybersecurity Expert, essentially an individual that can function effectively as an IT cybersecurity tech with the added skills of an industrial control systems expert.

A synopsis of attack events is provided in the article, with the author’s conclusion that not enough is being done to secure industrial control systems and the risk exposure is substantial in terms of potential threats to personnel, environment, and economy. By providing your name and email address, you can obtain the white paper from the ISA website. Your time spent obtaining and reading the article will be well spent.

Thermoelectric Generator for Remote Site Power Generation

Some operations, by their nature, dictate the location in which they will be undertaken. An obvious example is oil and gas production, but there are many others. These sometimes challenging locations burden designers and operators with providing remote communications, even on site power generation. Remote installations can often be unattended, yet require reliable continuous electric power to operate. Establishing an on site power source requires thoughtful selection of technology and equipment to provide the best solution.

A thermoelectric generator is one of several solutions to consider as a power source at a remote location. Each generation technology has a set of attributes making it more or less desirable for an application under consideration.

Thermoelectric generators convert heat directly into electricity using a fuel source for heat, a hermetically sealed thermopile, cooling fins, and no moving parts. The TEG delivers a low maintenance and cost effective solution for remote power requirements, having operational and cost benefits over engine driven generators, batteries and solar sources for many applications.

The short document below provides an overview of thermoelectric generator operation and application. Talk to a product specialist about your need to power and communicate with a remote site. A thermoelectric generator may be an option you had not considered, but may prove to be the best solution.

Monitoring Generator Sets in Standby Mode Increases Reliability

Remote Monitoring of Electric Generator in Standy Mode

Electrtic generators used as backup power sources play a critical role in maintaining operations at many facilities. They may be automatically test run periodically, but still sit idle for extended times. Continuous remote monitoring of equipment condition can reduce the risk of a failed start.

Acromag, a globally recognized manufacturer of signal conditioning equipment, has authored an application note outlining the extent of remote monitoring that should be employed and how to accomplish it.

In-Line Thermal Flow Meters

Thermal dispersion mass flow meters provide an accurate means of mass flow measurement with no moving parts and little or no encroachment on the media flow path. There are a number of different configurations to be found among various manufacturers, but all function in basically the same manner.

Two sensors are exposed to the heat transferring effect of the flowing media. When the media composition is known, the mass flow can be calculated using the meter reading and the pipe cross sectional area. One of the flow meter sensors is heated, the other is allowed to follow the media temperature as a reference. The heat dispersion from the heated sensor is measured and used to calculate mass flow.

Some positive attributes of thermal dispersion flow meters:

• In-line and insertion configurations available to accommodate very small to large pipe sizes
• Rugged Construction – Stainless Steel with available protective coatings and other specialty metals
• No moving parts
• Measure liquid or gas in general, sanitary, and ultra pure applications
• Measurement not adversely impacted by changes in pressure or temperature
• Wide range of process connections 
• In-line versions provide unobstructed flow path
• Wide turndown suitable for extended flow range
• Back up sensors for extended life
• Sensors do not contact process media
• Flow and total flow measured
• 4-20 mA output interfaces easily with other instruments and equipment
