METHOD AND DEVICE FOR COAL COMBUSTION IN SWIRLING FLOW

摘要

FIELD: heating. ^ SUBSTANCE: method of coal combustion in swirling flow includes tangential gas injection, coal supply and combustion productions removal. Coal combustion method is implemented using inert material in the area of two swirling flows interaction arranged in series each after another along combustible gas movement. In addition unburned coal and inert material particles are caught after their release from the second swirling flow by means of centrifugal field and returned again to the first swirling flow through coal supply unit for second afterburning. Optimal value of coal and inert material particles movement velocity in swirling flows is achieved due to the change of flow sections in channels with tangential gas injection. ^ EFFECT: effective method of coal combustion with improved process and environmental parameters. ^ 3 cl, 2 dwg
