![]() ![]() Steam produced in the HRSG will be used in the ST to produce additional electrical power. Hot gases produced in the combustion turbine will be transferred to the HRSG through an exhaust transition duct, where waste heat will be captured and converted into steam. The generator will convert the mechanical energy into electricity. Rotating shafts will transmit the mechanical energy to the generator, which will be directly coupled to the power turbine. “The natural gas-fuelled power project is expected to serve up to more than one million homes.” The H-Class turbine comes with a simple configuration and modular system, the installation of which takes 10,000 lesser man-hours than the 7F.03 gas turbine. Natural gas blended with ethane will be the primary fuel for the plant. The turbines and the associated HRSGs will be equipped with a selective catalytic reduction (SCR) system to minimise nitrogen oxide (NOx) emissions and an oxidation catalyst to minimise carbon monoxide (CO) and volatile organic compound (VOC) emissions.Īuxiliary equipment for the project will include a cooling tower, a natural gas-fired auxiliary boiler, two natural gas-fired dew point heaters, two ultra-low sulphur diesel (ULSD) fired emergency backup generators, and a firewater pump. ![]() To be located on a 30-acre site in Johnstown, the combined-cycle facility will consist of two 7HA.02 high-efficiency air-cooled gas turbines in a two-on-one configuration, coupled with two heat recovery steam generators (HRSGs) and a steam turbine. ![]()
