Gas engines tap into an available energy sources, such as industrial waste gases, to achieve CO2 emission savings. Steel production processes typically create large volumes of specialty waste gases. Coke oven gas, generated during the processing of bituminous coal into coke in coke oven batteries, mainly consists of hydrogen and methane. Also, LD-converter gas is created during the steel manufacturing process that converts pig iron to steel. In the past, operators used these steel waste gases to only produce steam in gas-fired boilers. This new technology allows steel factories to also generate electricity while avoiding the need to vent these gases into the atmosphere. (Jenbacher by GE Energy) www.gepower.com #18

Thermocouple assembly provides a reliable temperature monitoring sensor for high-purity fluid systems that traditionally use fluoropolymer components.

Gas turbine is driven by a type of internal combustion engine that can be viewed as an energy conversion device that converts energy stored in the fuel to useful mechanical energy in the form of rotational power. The term “gas” refers to the ambient air that is taken into the engine and used as the working medium in the energy conversion process. This air is first drawn into the engine where it is compressed, mixed with fuel and ignited. The resulting hot gas expands at high velocity through a series of airfoil-shaped blades transferring energy created from combustion to turn an output shaft. The residual thermal energy in the hot exhaust gas can be harnessed for a variety of industrial processes. (by Solar Turbines) www.mysolar.cat.com #33
