In Rēzekne, Latvia HoSt has built a wood-fired CHP plant. The plant supplies approx. 3 MWe of electricity to the net and approx. 11MWth of heat to a wood drying system of a wood pellet production plant, through a hot water circuit. Wood waste of the pellet production plant is used as fuel for the CHP.
HoSt has built this plant as a turn-key supplier. The construction was completed within the agreed schedule and the plants meets all the agreed performances and requirements.
|START PROJECT||August 2014|
|START-UP / FIRST FIRE||August 2015|
|Wood storage||250 m³|
|Wood supply system||Chain scraper|
|Flow temperature||15 °C|
|Furnace||16.5 MWth – 7,3 t/h at 45% H2O|
|Water tube boiler||14,4 MWth|
|Steam turbine||3,1 MWe at 80 °C|
|Steam condensor||10,7 MW at 80 °C|
- The water tube boiler has a very high availability
- The fouling of the boiler and furnace is minimized due to low speeds and a low temperature on the grate
- High efficiency is achieved through a combination of low flue gas outlet temperature, a low oxygen content in the flue gas, and an efficient steam turbine
