Jenbacher has launched a 4 MW, J624 GS gas engine, its first 24-cylinder unit.
Initially, the new engine will be operated with natural gas, and its first customers will be greenhouse operators in the Netherlands.
With an electrical output of 4 MW, a single J624 GS used as a cogeneration application produces about 3.6 MW of heat, allowing for overall plant efficiencies of up to 90% using about 870 m3 of natural gas an hour, the company says.
In the next step, this engine will be used for coal mine gas solutions. The new high speed, 1,500 rpm, turbocharged 4 MW engine is the latest Jenbacher type 6 unit. Volker Schulte, leader of the research & development department for GE’s Jenbacher gas engines, said: “We managed to meet a number of technological challenges in designing this new engine. These include designing both engine and turbochargers for an extremely high mean effective pressure, controlling the vibrations by decoupling the intercooler and turbochargers, optimising the combustion sequence, and increasing the mechanical strength of the crankshaft.”
