Stoichiometric Combustion - Engineering ToolBox

Stoichiometric or Theoretical Combustion is the ideal combustion process where fuel is burned completely. A complete combustion is a process burning all the carbon (C) to (CO 2), all the hydrogen (H) to (H 2 O) and all the sulphur (S) to (SO 2).. With unburned components in the exhaust gas such as C, H 2, CO, the combustion process is uncompleted and not stoichiometric .

Biomass Combustion - FSA1056

Biomass boilers has different burning method from coals. The SO2, smoke and NOX emission are less than coals. The burn out rate is higher than coal, so the ash residue is little. As the ignition point of biomass fuel is far lower than coal, you can't bank fire when you blowout the furnace temporarily. So the biomass boilers need operate continuously, and the biomass fuel consumption is higher than coal.
