Avoiding freezing and leakage: Optimal thermal management for the use of molten salt in solar thermal power plants with concentrated radiation

The demand for environmentally friendly and low-CO2 forms of energy generation has been increasing in Europe since the “Green Deal” was presented by the EU Commission in 2019, defining the climate neutrality of 26 member states up to the year 2050. Among other methods, the focus is on solar energy as an important representative in this area.

How to Replace Sensors on Process Heaters

Process heaters, such as immersion heaters, use a range of sensor options to accurately measure and adjust the heat of a manufacturing process. If you’re a design engineer using the latest heating products, your process heater typically uses one of these three types of sensor:

How Watt Density Specifications May Be Holding Back Optimal Electric Heat Exchanger Design

Typical customer specifications for a direct electric heat exchanger (DEHE) in forced convection gas applications aim for efficiency and safety given the technology principles that have been in place for the last two decades. For example, this has led to specifications calling for lower heat fluxes (watt densities) to maintain safe sheath temperatures reliably. More recently, newer technologies allow for higher watt densities while maintaining both safety and reliability. While the older specifications are conservative and safe, the design may be sub-optimal. Letting go of the assumption that watt density is roughly equivalent to a safe sheath temperature helps open up the possibilities of new design solutions, many of which can reduce overall footprint and make processes more efficient and less costly.

Better predicting terminal enclosure temperature to improve heater reliability

One of the most common failures in electric process heaters used in various industrial applications involves electrical terminations and not the heating elements. Engineers at Watlow® believe designers across the industry are underestimating the temperature profile from the heater flange to terminal enclosure in these thermal systems.

Decarbonization, Electrification and the Case for Modern Electric Process Heaters

Companies in liquified natural gas (LNG) and other industries have been taking bold steps to reduce their carbon footprint. The overall strategy of these companies is to tackle carbon emissions not only through alternative energy investment and increased efficiency, but also through converting key industrial processes (like process heating) to electric (rather than fuel-fired). This paper explores pressures to electrify process heating, as well as the role that electric heat exchangers are playing, particularly in light of innovations in the design of these heaters.

Better Heaters Mean More Innovative Analytical Equipment Designs

How ULTRAMIC® advanced ceramic heaters offer more design flexibility for mass spectrometers and other pieces of analytical equipment Advanced ceramic heaters offer a number of benefits when it comes to the design and marketing of analytical equipment. Many of the heaters used in today’s analytical equipment are metal-sheathed heaters based on legacy technology designed some 20 or 30 years ago, potentially limiting design innovation. By contrast, today’s advanced ceramic heaters are smaller, respond faster, can be more accurately controlled and can be more resistant to environmental contamination. They also offer more design flexibility and are easier to integrate into equipment, simplifying the manufacturing and assembly process. Watlow’s ULTRAMIC advanced ceramic heaters in particular can help analytical equipment manufacturers improve product performance and design, as well as accelerate their time to market.

Determining Temperature Class for Electric Process Heaters

Electric process heaters that interface with flammable materials in explosive environments need to be properly evaluated to protect the equipment against catastrophic failures. There are several possible protection methods that may be employed to protect from a potential explosion. A temperature class requirement will be provided by the user based on the explosive gases that may be present in the installation area. The maximum surface temperature of the process heater must then be evaluated to assure compliance. Temperature classes that are based on the maximum operating temperature for heaters prescribe the level of safeguards. Determining the temperature class for a specific electric process heater is unique compared to other electrical components installed in classified locations. The temperature code, or T-code, is highly dependent on the process conditions of the heating application. Global Temperature Classes/Codes are broken down into the following various levels.

Raising reliability

Scott Boehmer and Mike Bange, Watlow, USA, outline how heater reliability can be improved by better predicting terminal enclosure temperature.

Energy Process Heaters Failing Because Of Different Kind of Heat

It has generally been assumed in energy process heaters that pins attaching heating elements to the power terminal do not generate heat on their own. That is why they are called cold pins. Engineers at Watlow believe cold pins actually generate heat creating an environment that is leading to heater failures.
