Integrated Gasified Biomass Power Plant
GE, EQTEC Iberia team to increase Bulgaria’s energy independence
To reduce Bulgaria’s heavy dependence on imported energy, a biomass-to-energy plant powered by GE’s Jenbacher gas engine technology is being built near Stroevo, in Plovdiv province.
Scheduled for completion by the end of 2014, the plant is being built by EQTEC Iberia, part of Spanish holding company Ebioss Energy AD.
The 5 MW Karlovo plant will use three of GE’s Jenbacher engines – one J612 and two J620 units – powered by syngas derived from straw and wood chips. Such organic waste is normally difficult to gasify effectively, but tight integration of EQTEC Iberia’s biomass-gasification technology with GE’s engines will provide high levels of emissions performance, efficiency and economy, the company said.
Bulgaria’s target is for 16% of its energy demand to be met by domestic renewable sources by 2020, but at present more than 70% of its energy is from imported natural gas and oil.
Syngas is attractive because it is a continually renewable fuel that enables power to be produced economically on-site at the point of use, reducing losses inherent in electrical transmission. It also helps to solve a waste-disposal problem by converting organic wastes into fuel. With the EQTEC gasifier technology, steam and hot water can be generated with no reduction in output power, so overall plant efficiency will be much higher when the plant is used for district heating or other cogeneration applications in addition to power production, the company said.
