Fire grate free boiler

Abstract

The invention relates to a boiler, in particular to a fire grate free boiler. A shell has a sandwich structure and is internally provided with a water jacket, and the cavity of the shell is internally provided with an upper partition board, a left horizontal pipe and a right horizontal pipe; two ends of the left horizontal pipe and the right horizontal pipe are all fixedly connected with the inner wall of the shell and communicated with the water jacket; the position of the lower end of the upper partition board is higher than the positions of the left horizontal pipe and the right horizontalpipe and the upper part of a hearth is divided into two combustion chambers by the upper partition board; the left horizontal pipe and the right horizontal pipe are respectively and fixedly connectedwith a left inclined pipe and a right inclined pipe, respectively extend towards the left side and the right side, are fixedly connected with the inner wall of the shell and communicated with the water jacket. The fire grate free boiler adopts the inclined pipes with special structures to support coal to replace the fire grate, and omits an independent fire grate, so the structure is simpler, thecoal is fully combusted, tail gas pollution is less and the aims of saving energy and protecting environment are achieved.

Description

technical field [0001] The invention relates to a boiler, in particular to a boiler without a grate. Background technique [0002] Existing boilers are all provided with horizontal fire grates in the furnace, and coal and other fuels are placed on the fire grates for combustion, and the hot gas produced during combustion rises to heat the water in the boiler. This kind of traditional boiler coal is still on the grate when it is burning. The coal in the central part only contacts with oxygen through ash and slag, which is often prone to insufficient coal combustion, low thermal efficiency, and high energy consumption. The problems of excessive exhaust gas and serious dust pollution do not meet the requirements of environmental protection and energy saving. Contents of the invention [0003] The object of the present invention is to provide a grateless boiler with simple structure, high thermal efficiency, no black smoke and less pollution. [0004] To achieve the above ...
