Abstract

The utility model relates to a horizontal type back-fire coal-fired boiler which is characterized in that a back-fire coal-firing mode is adopted in the boiler. Three water wall partition boards are perpendicularly arranged in a boiler body, wherein two water wall partition boards are upper water wall partition boards, the third water wall partition board is a lower water wall partition board, the water wall partition boards divide the boiler body into three combustion chambers and a burn-out chamber, a second combustion chamber, a third combustion chamber and the burn-out chamber form a multi-return-stroke flue structure, the path of smoke flow is of an N shape, a fire-watch hole and an ash-discharge hole are formed in a side face of the boiler body, and a first-layer water pipe grate and a second-layer water pipe grate are arranged on the lower portion of a first combustion chamber. The horizontal type back-fire coal-fired boiler has the advantages that the multi-return-stroke structure is adopted, thus fuel can be burnt sufficiently, heat energy can be released effectively, and environmental protection effect is good. Further, two-layer water pipe grates are arranged in the first combustion chamber, thus the boiler is fast in temperature rise, thermal efficiency is high, and energy-saving effect is good.
