CHP application: renewable and local power and heat production

High efficiency due to lean burn combustion

Maximized fuel efficiency in fixed installations of combustion engines is generally achieved by applying the concept of lean burn. Due to this principle, the engine can use a higher compression ratio and thus a higher level of efficiency and more efficient fuel use. However, lean burn engines demand stable fuel supply conditions and they cannot tolerate a quickly changed heating value or flow rate.

To the knowledge of Meva Energy, Meva’s technology is the only gasification system in the world being able to use lean burn CHP engines.  The reason is simple; the incomparably continuos and stable character of the process ensures that the gas supply exhibits extremely small level of variation.

“Meva’s cyclone gasification technology applicability with low grade and low cost biomass constitutes a truly disruptive new power technology enabling a greatly improved utilization of such biomass”

CHP application in a wide range of installations

The technology is suitable for several different applications characterized by fuel type and heat application. Possible applications for the current set-up of 1.2 MWe and 2.4 MWth include:

  • Industry: chemical plants, saw mills, refineries, laundries, food industry, plastic molding industry, farming and green houses
  • Commercial: office buildings, airports, shopping malls
  • Residential: DHC systems, multi-family housing, planned communities, hotels
  • Institutions: schools, nursing homes, prisons, hospitals

Beside having maximum utilization of the produced heat, the key to reach maximum profitability conditions is to use a low cost fuel. As the system can use saw dust as fuel, one particularly interesting segment is saw mills and wood-producing industry where saw dust is a by-product.
