Burmeister & Wain Energy A/S
Description
BWE is an international Hi-Tech company which has specialized in design of
Biomass high efficiency boilers with Super Critical steam data. BWE offers both Biomass fired natural circulated drum type boilers and high efficiency once-through boilers (Benson) with Super Critical steam data.
For combustion of Biomass three different firing systems can be supplied:
•Grate firing of straw delivered as bales
•Grate firing of chips-like Biomass with pneumatic spreaders
•Traditional Low-NOx burner firing with milling plant for pellets
Grate firing is available for fuel input up to 150 MW. BWE uses a water cooled vibration grate firing technique. This requires less fuel preparation than e.g. pulverized fuel firing. Fuel handling and preparation equipment is therefore substantially reduced compared to Low-NOx burner applications.
The burner firing technique has the advantages of high fuel inputs and multi fuel abilities. Biomass pellets is a rather standardised fuel that can be utilized using traditional coal firing equipment, including milling plant and pneumatic transport. BWE has developed this technique to a flexibility where the fuel range goes from 100% coal to 100% biomass pellets. BWE Low-NOx burners of today operate on natural gas, LFO, HFO, pulverised coal and Biomass pellets - all in one unit.
