Firewood and coal dual-purpose half-gasification multifunctional heating boiler

Abstract

The invention discloses a firewood and coal dual-purpose half-gasification multifunctional heating boiler. In a boiler body provided with a water jacket, an ash falling chamber, a water pipe type fire grate and a gas generating chamber are sequentially distributed from bottom to top, wherein the ash falling chamber is arranged at the bottom, the gas generating chamber is arranged on the water pipe type fire grate, the gas generating chamber is connected with a fire gathering cover, and the upper part of the boiler body is provided with a smoke outlet. The firewood and coal dual-purpose half-gasification multifunctional heating boiler is characterized in that the inner wall of the gas generating chamber is provided with a water pipe communicated with the water jacket of the boiler body, the water pipe is provided with a rib, and the fire gathering cover on the gas generating chamber is provided with a secondary air inlet hole. The invention has the advantages that by utilizing a windward channel formed by a water pipe with the rib, fuel is burnt from the edge to the middle, the generated gas and soot enter a combustion chamber and are sufficiently burnt, and the discharge of combustible material can be reduced. The invention is suitable for multiple fuels of coal, straws and the like, can be used for heating, boiling water, cooking and warming kang, and is especially suitable for heating in winter in the north of China.

Description

technical field [0001] The invention relates to a heating boiler, in particular to a semi-gasification boiler. Background technique [0002] At present, the heating boilers sold on the market usually have a design structure: the furnace body is provided with a water jacket interlayer or row pipes, and the flue connected to the furnace body is also provided with a water jacket to increase the heat exchange area.
