METHOD FOR BURNING PULVERIZED COAL FUEL IN FURNACE OF STEAM BOILER WITH LIQUID SLAG-TAP REMOVAL

摘要

A method for burning pulverized coal fuel in furnace of steam boiler with liquid slag-tap removal includes supply of pulverized coal fuel and air to each semi-furnace with counter-flows with same diameters with distribution of those at lower and upper layers. Pulverized coal fuel and air are supplied in three flows. Distribution at upper level is performed by two flows, at lower - by one flow directed between flows of the upper layer. Distance from axis of flow of lower level to slag fill is kept equal to one diameter of flow.
