COST ESTIMATES FOR CAPITAL EXPENDITURE AN

< 2013-5-20 · 2.2 Conventional Boiler Technology Direct-fired systems are the conventional and industry standard utilized to produce steam for heat and electricity generation from biomass in the United States today. In direct-fired systems, the biomass fuel is directly burned (combusted) in a furnace or combustion unit that then supplies heat to a boiler.
