Wet combustion process

摘要: Aqueous solutions and suspensions of solid particles, even those containing less than one percent organic materials, may be combusted with air, oxygen, or their mixtures in a process which provides for preheating countercurrent batches the raw original liquid by either open (direct contact) closed (heat transfer surface) condensation steam generated multiple flash evaporations cool earlier hot after wet combustion. Excess heat often withdrawn from power generation other use as high pressure steam, without combustion gases non-condensibles. No pumps are necessary, pressurized only vessel is required instead many continuous processes. Waste liquids sewage sludges black liquors wood pulping have constituents, measured BOD COD, so reduced that final, spent discharged directly to receiving body water.
