2013 - Biomass CHP Boiler Plant 5.4 MW Thermal and 995 kWe Turbine Capacity

Biomass CHP Boiler Plant – 5.4 MW Thermal and 995 kWe Turbine Capacity

A lightly operated, complete biomass CHP boiler plant featuring a 9.5 MW bubbling fluidized bed boiler (BFB), designed for wood-based fuels. The plant includes a back-pressure steam turbine and a heat exchanger for hot water production from back-pressure steam.

The plant was built by Estonian Filter Solutions, a company highly experienced in steam boiler plant engineering and EPC contracting. The BFB steam boiler was delivered by Vapor Boilers Finland. The steam turbine was manufactured by Triveni Turbines (India), in combination with a generator and controls from ABB. Other key equipment includes KSB pumps, conveyors from Technobalt AS, and rotary airlock valves from Rotolok UK. The power plant was commissioned in 2013 and operated at partial load until 2015.

The control system, developed by Filter Solutions, is installed on PCs and includes standard visual process screens. The control room is located remotely from the plant. Local process controllers are Siemens S7-00 series PLCs, except for the steam turbine, which uses Honeywell controllers.

Delivery includes the complete technological system—from the fuel receiving station to the outgoing 400 kV switch breaker in the electrical system, and to the hot water pumps for thermal energy distribution. A metal-frame building with sandwich-type panels and integrated building technology is also included.
