Reconstruction of the Põltsamaa 500 KW boiler house


• Pellets with a capacity of 500 kW (maximum working pressure Ps = 6 bar, maximum working temperature Ts = 110 oC) with a pellet burner (500 kW) were installed in the boiler room. This pellet boiler set is designed to work as automatically as possible. Pellet containers are filled with a blower, from where it is delivered to the pellet burner using a feed. The pellet containers have filling sensors, bringing the filling pipeline outside the building.

• Ash removal is provided dry, and ash is collected from the bottom of the boiler and under the multicyclone, after which the ash moves to the ash box in the boiler room.

• A smoke fan removes flue gases from the pellet boiler, and a multicyclone is used to clean flue gases from volatiles. The smoke passages are insulated and equipped with the necessary control and cleaning hatches. Flue gases are led into a pre-insulated stainless steel modular chimney compatible with the new heating system dsise=300mm; height 10 m.

• To prevent corrosion, the biofuel boiler has a self-circulation pump (minimum return temperature T = 70 oC) and multi-step protection automation.
