ABSTRACT:
A pressurized combustion of slurries of low-cost, unbeneficiated solid fuels in the presence of steam and alkali in which sulfur oxide emissions are inherently low, emissions of nitrogen oxides controlled by the injection of a scavenging agent and emissions of particulates prevented by condensing steam on and around them. The combustion has applications to steam boilers, combined cycles and gas turbines, including steam injected (STIG) and intercooled steam injected (ISTIG) versions. Turbine blade and nozzle erosion and deposits are avoided by the effective wet separation of ash particles before reheating and expansion.
