AN INCINERATION METHOD AND APPARATUS FOR NON-FOULING TREATMENT OF SPENT WASH

Abstract

The present disclosure teaches an incineration method and apparatus for non-fouling treatment of spent wash wherein primary air is.injected in to a first chamber (12) while secondary air and tertiary air are injected into a second chamber (14). The primary air, the secondary air and the tertiary air are injected in predetermined proportion to substantially convert spent wash injected into the incineration apparatus into flue gases. The heat from the flue gases are progressively extracted in the second chamber (14), a third chamber (16) and a fourth chamber (18) using non-thermic fluid. This prevents agglomeration of the fluidized bed, slagging on walls and tubes associated with the second chamber (14), the third chamber (16) and the convection tubes within the fourth chamber (16), thereby preventing fouling of the incineration apparatus while ensuring efficient removal of ash from the flue gas.
