Vertical-pipe outer wall-heated non-pressure boiler

Abstract

The invention provides a vertical-pipe outer wall-heated non-pressure boiler, which comprises a boiler body, wherein the boiler body consists of an outer wall, an inner wall, a sealing head and a top plate and is provided with a smoke pipe, an atmospheric air channel port, a water outlet, a water return port and a furnace door; the internal lower part of the boiler body is provided with a combustion chamber; the lower part of the combustion chamber is provided with a furnace grill; and a slag chamber and a slag outlet are formed below the furnace grill. The non-pressure boiler is technically characterized in that: the upper part of the combustion chamber is provided with a heating pipe which is vertically communicated with the upper cavity and the side cavity of the boiler body; and the vertical heating pipe consists of an L-shaped heating pipe which is distributed circumferentially and a spoon-shaped heating pipe and an L-shaped heating pipe which are alternatively distributed circumferentially. When the non-pressure boiler is used, water in the vertical heating pipe and the cavity of the boiler body is heated quickly by the combustion of a fuel in the combustion chamber. Due to the adoption of vertical pipe distribution, stain and dust are prevented from being accumulated on the outer wall of the pipe, and scale formation is prevented during internal circulation, so that effective heat absorption area is increased, heat conducting effect is enhanced greatly, thermal efficiency is improved, reactive heat loss is reduced and energy conservation, low carbon and environmental friendliness effects are achieved.

Description

technical field [0001] The invention relates to a boiler device, in particular to a non-pressure boiler which can be used in small and medium-sized township enterprises, self-heating houses, large and medium farms, etc. Background technique [0002] At present, most of the commercially available boilers adopt horizontal tubes or folded plates, and stains and dust accumulation are inevitable on the upper part, which reduces the effective heat absorption area. Horizontal pipe layout makes the internal circulation of the boiler slower, and is perpendicular to the direction of gravity. The inner wall of the pipe is easy to scale, which reduces its thermal conductivity and affects the thermal efficiency of the boiler, which is not conducive to energy saving. Contents of the invention [0003] In view of the above situation, the purpose of the present invention is to provide a high thermal efficiency, energy-saving vertical pipe outer wall heating type non-pressure boiler.

AI Technical Summary

Problems solved by technology

Horizontal pipe layout makes the internal circulation of the boiler slower and perpendicular to the direction of gravity. The inner wall of the pipe is prone to fouling, which reduces its thermal conductivity and affects the thermal efficiency of the boiler, which is not conducive to energy saving.
