sum of the biomass fuel cost, non-fuel O&M cost, and a capital recovery cost, all on a per kWh-generated The energy requirements and outputs for three sizes of stoker boiler systems from 100 to 900 tons/day are shown in .

Fuel cost is usually the dominant component, accounting for as much as 90% of the total. It is given by: CF = aF x (HS hW)/1000/η B where aF = fuel cost, ($/MMBtu) HS = enthalpy of steam, Btu/lb hW= enthalpy of boiler feedwater, Btu/lb η B= overall boiler efficiency, fractional.

Are biomass boiler costs justified? - SuperHomes
For an average sized house, a basic log boiler might cost about £3,000, while one with a higher standard of controls might be £6,000. A pellet-fired boiler could cost £9,000. For the total installed cost (including flue, accumulator tank, fuel store, etc), add maybe £12,000 to £15,000 to those boiler costs.
Different energy sources are measured in different units: litres, therms, BTU, kWh, units, cubic metres and many more. This makes it very difficult to compare the actual costs for powering a heating system between different energy sources. For this reason, standardised units and costs are needed. We have done these calculations for the main fuel
