Jenbach, Austria: A new gas engine promises to open up wider possibilities in the fields of CHP and distributed generation. The Jenbacher J624 engine will increase energy output by 10% and electrical efficiency by 1% in addition to providing other operational benefits, compared to its predecessors.
The manufacturer, already a world leader in reciprocating engines for power generation, notes that the GE Jenbacher 624 gas engine, rated for 4.4MW and 46.5% simple cycle efficiency, is the world’s only 24-cylinder gas engine. The new design features 2-stage turbo charging to achieve the highest possible power density and efficiency while still being suitable for continuous duty applications. The 2-stage turbo charger increases the electrical efficiency compared to a single stage turbo charger. The result is electrical efficiency close to 46.5% before counting heat recovery.
The new engine also offers customers greater flexibility, especially for projects in hot, humid environments and for combined heat and power applications.
