01/12/2008 · This is very different with biomass conversion process in a grate-fired boiler, where biomass fuels are slowly heated, dried, and pyrolysed as they are transported on the grate, and finally the char will be combusted at high temperatures, about 10001100 °C (see Fig. 5 for this process). These differences will significantly affect the volatilization of particle-forming precursors.
Some of these options require extensive plant modifications, such as boiler conversion from coal to natural gas or repowering of an existing coal-fired power unit to combined cycle unit burning natural gas. Others, such as optimization, are strictly plant-operating adjustments. Most of these options are very site-specific, especially with regard to the potential emission reduction and the
The boiler utilized wood as the primary fuel and natural gas as start-up and backup fuel. The combustion unit was a pyrolysis system designed to gasify wood in the initial combustion zone at sub-stoichiometric air rates. The initial combustion zone is on the stoker grate. Complete combustion of the off-gases from the pyrolysis process occurs in
01/06/2011 · 5.28 0.88 2.4.3. The first one is the high yield of dry material per unit of land (dry tons/hectare). A high yield reduces land requirements and lowers the cost of producing energy from biomass. Secondly, the amount of energy, which can be produced from a biomass crop, must be less than the amount of energy required to grow the crop. Generally, the cost of producing energy from
