A recent trial has proven that Endress+Hauser temperature probes with thermowells made from a new alloy can withstand extreme temperatures up to 1000ºC that are typically found in the furnace of an energy-from-waste facility.

Temperature: a critical measurement in a harsh environment

In energy-from-waste plants furnace temperature is a critical measurement. By burning the waste at an optimum temperature the release of harmful emissions is avoided. In order to accurately record the temperature in the furnace, three or more temperature thermowells are inserted into the furnace directly above the flame. Due to the incredibly harsh conditions in the furnace, conventional probes made from Incoly 800HT alloy will typically fail after three or four months of service. As the probes are sited in an elevated position, changing them can be difficult. In addition, each time the furnace is opened there is the possibility that cooler air will enter or that hot gases will escape, both of which can decrease the efficiency of the process and cause health and safety concerns.

Rotork’s innovative CVA electric actuator has been specified for critical valve control duty on high temperature gas turbine pre-heater equipment supplied to the power generation industry. The application demands unrestricted modulation of a three-way valve to control the pre-heated temperature of fuel gas for electricity generating turbines.

A wide range of Flue Gas Analyzers are now offered from Wahl Instruments, Inc. Included in our Test & Calibration equipment catalog, two different lines of analyzers are available; both G Line and U Line models are offered to serve the industrial or professional HVAC technician, including those in compliance with EPA Protocols CTM-030 and CTM-034. The most commonly fuels are pre-loaded at the factory, with other fuels available with included GasConfig software for PC on most models. By measuring the quantities and concentrations of gases present in exhaust, these combustion analysis tools allow the user to maintain the safest and most efficient conditions possible for their environment and equipment. Detect Carbon Monoxide, Nitrous Oxide, and uncombusted hydrocarbons in the exhaust gas from a combustion process to ensure the safety of your employees and the efficiency of your equipment. Identify maintenance problems that develop over time, as boilers deteriorate and efficiency drops.

HATFIELD, Pa. (December 9, 2011) – Brooks Instrument, a world-leading provider of advanced flow, pressure, vacuum and level solutions, introduces the GF40 and GF80 thermal mass flow controllers (MFCs). These MFCs provide outstanding performance, reliability and flexibility in many gas flow measurement and control applications.

The Brooks GF40/GF80 offers a highly configurable platform based on modular architecture, enabling drop-in replacement for quick and easy upgrades. These MFCs give users an opportunity to standardize on one MFC over a broad range of applications providing reduced inventory and operational costs.

The GF40/GF80 MFCs operate with Brooks' patented MultiFlo™ technology enables superior actual process gas accuracy. MultiFlo also gives users the ability to reconfigure the MFC for a new gas and range without the time and cost of removing the device from the gas line. The MFCs are also equipped with an independent diagnostic/service port to troubleshoot or change flow conditions without removing the MFC from service.
