THE FURNACE TO BURN FUEL INTO MELTED SLAG

摘要

The invention relates to heat-and-power engineering, particularly, to the devices for solid fuel firing, processing of thermal and thermal condensing power plants ash wastes (AW) in a melted slag, bubbled by oxygenated gas, and getting refuse-to gas energy. The invention provides to increase maintainability of the furnace for fuel firing in melt (FFFM) by the development of a hearth and a hearth enclosure construction, mounting of a gas seal device along the power boiler girth at the power boiler-furnace conjunction and selection of the furnace optimal length. The FFFM hearth includes the mounting of padded caissons on the refractory masonry surface and embedded ones - into the hearth masonry at the depth of 10-12 gages of air tuyeres of embedded caissons. The mounting of the gas seal device along the power boiler girth provides to eliminate both the leak-in from atmosphere and the exhaust gases discharge.
