Evaporative concentration of waste sludges with incinerator exhaust gases
Patent
·
OSTI ID:7279730
Waste sludges containing a high proportion of water are concentrated by an evaporative process prior to fluid bed incineration. The evaporation is carried out in a scrubber-evaporator into which air at high temperature is passed, the high temperature achieved by heat exchange with the incinerator exhaust gases. The exhaust gases are also passed through an additional heat exchanger to preheat the fluidizing-combustion air feed to the fluid bed reactor. The exhaust gases are treated in a venturi scrubber before discharge to the atmosphere.
