| GE Energy introduces new Jenbacher gas engine  GE Energy has introduced a new Jenbacher J420 GS gas engine to its Type 4 engine family that is ideal for 60 Hz applications running at 1,800 rpm to serve the high-efficiency power generation, cogeneration and onsite power segment in North America. GE's new 60 Hz model offers customers high efficiency at high specific outputs with 1,800 rpm, suitable for natural gas or a variety of other gases, such as landfill gas, biogas, sewage gas, glare gas and coal mine gas. GE's new Type J420 GS for 60 Hz applications is characterized by a high power density due to its compact, robust design and small footprint.Key advanced efficiency features include swirl-optimized, four-valve cylinder heads, a Miller timing combustion system and high-performance spark plugs. This leads to lower fuel costs, and longer operating periods for components, including cylinder heads for up to 30,000 hours and spark plugs for up to 15,000 hours, resulting in overall attractive costs of electricity. Electrical output of the new model is 1.426 MW, while thermal output will be about 5,700 MBTU/hr when fueled by natural gas and 5,400 MBTU/hr with biogas. Electrical efficiency is 40.8%, with a total engine efficiency of up to 86.6%. The first J420 for 60 Hz applications will be shipped in late 2006, with the first field installation entering service during the first quarter of 2007. write your comments about the article :: © 2006 Construction News :: home page |
