20 Tons Biomass boiler Operating Costs Kefid 08:27:05. When customers choose biomass boiler, they will consider the operation cost of the boiler. In addition to labor cost, water cost, electricity cost, maintenance and overhaul cost, the cost of fuel accounts for more than 90%.

A properly insulated flue, needed for efficient operation of a biomass boiler, can cost around £2,000 to £2,500. An accumulator (or buffer) tank could cost about £1 per litre. It will probably be sized to between 50 and 100 litres per rated kW for a log boiler. A pellet boiler needs a smaller accumulator, at maybe 20 litres per rated kW.
above.The lime or limestone reacts with the SO 2 in the flue gas to create insoluble calcium sulfite (CaSO 3) as in the equations below. Limestone: CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g) Lime: Ca(OH) 2 (s) + SO 2 (g) → CaSO 3 (s) + H 2O (l) The resultant calcium sulfite may be further reacted with oxygen to produce gypsum (CaSO ¬4·2[H 2O]) by the fol-lowing reaction.
03/11/2006 · On the basis of a great number of international and national references about flue gas desulfurization, this paper presents a process called Limestone Wet Flue Gas Desulfurization which is suitable for experiment.Limestone wet gas desulfurization ( WFGD ) technology with high desulfurization efficiency is being applied widely for coal-fired Power Plant all over the world.

collect slurry droplets and remove moisture from the flue gas. In some installations, the flue gas is reheated to avoid corrosion downstream in the power plant. Many scrubbers have gas-bypassing capability, which can be used for gas reheating. Also, gas-to-gas reheating may be used, which does not have a penalty on plant efficiency. The figure shows conventional limestone/lime flue-gas desulfurization.

If we are just considering the plant room then a biomass boiler will make up around 55% of the project cost, with the other components around 30% and finally labour will be about 15%. A basic domestic installation with a 20kW system will cost around £15k, then larger more commercial systems will be around £32,500 for a 50kW, £42,500 for a 100kW, £80,000 for a 250kW, £160,000 for a 500kW
