SLURRY TREATMENT AND COMBUSTION CHAMBER TO IMPROVE COMBUSTION

摘要

A method and apparatus for increasing the speed and efficiency of combustion of slurries containing water and porous particles of carbonaceous material. The slurry is pressurized and elevated in temperature prior to delivery into an area of reduced pressure. This reduction in pressure causes the water in the pores or voids of the particles to flash boil and shatter the particle to form a number of smaller particles which burn more easily. This steam explosion preferably takes place in a combustion chamber (15, 16) which may also include a target (14) against which a proportion of larger, heavier particles of carbonaceous material in the injected slurry impact and shatter to form a number of smaller particles.
