“Using syngas as a fuel is uncommon in such plants and represents an innovative solution to the energy challenges Bulgaria and many other nations face; however, it is challenging to develop an integrated gasification design that doesn’t produce syngas containing impurities that can foul engines. The selection of technologies to work together is important; and the Karlovo plant features EQTEC Gasifier Technology, which produces cleaner syngas,” said Leon van Vurren, global sales leader, Jenbacher gas engines for GE’s Distributed Power business. “At the same time, GE has a proven technology suited to this type of application—GE’s Jenbacher gas engine, which has fuel flexibility and robustness that make it known for its performance even with non-traditional fuel gases.”
This isn’t the first time EQTEC and GE have worked together. The collaboration debuted in 2008 with an IBGPP cogeneration plant in Spain at the alcohol distillery of the company MOSTOS, VINOS Y ALCOHOLES, SA (MOVIALSA) at Campo de Criptana in the La Mancha region. The plant is fueled by the gasification of residual materials from olive oil production. It uses three J620 Jenbacher engines producing a total of 5.9 MW of electricity, 5,600 Kg/h of saturated steam at 6 bar and 159 m 3/h of hot water at 90°C, which are used by the distillery. Together, these yield an overall plant efficiency of 63.8 percent.
GE's Jenbacher J612 and J620 gas engines running on syngas from renewable biomass are part of GE’s ecomagination portfolio. To qualify for the ecomagination portfolio, products and services must demonstrate both improved economic value and environmental performance. Ecomagination is GE's commitment to innovative solutions that maximize resources and efficiencies and make the world work better. Overall, GE's Jenbacher gas engines product line has almost 100 units installed and operating on syngas from waste and biomass with an electrical output of about 100 MW.
GE Power & Water’s Distributed Power is a leading provider of power equipment, engines and services, focused on power generation at or near the point of use. Distributed Power’s product portfolio includes GE’s aeroderivative gas turbines and Jenbacher and Waukesha gas engines, which generate 100 kilowatts to 100 MW of power for numerous industries globally. Headquartered in Cincinnati, Ohio, Distributed Power employs about 5,000 people around the world.
