Abstract

The invention provides a water cooling wall arrangement structure of a straw boiler. With the adoption of the water cooling wall arrangement structure, heat can be fully exchanged between a water cooling wall and heat energy in the boiler, so that energy can be fully utilized, and the energy can be saved. The water cooling wall arrangement structure of the straw boiler comprises a boiler barrel, a hearth, a cooling chamber and a superheater chamber, wherein the upper part of the hearth is communicated with the upper part of the cooling chamber; the lower part of the cooling chamber is communicated with the lower part of the superheater chamber; and smoke in the hearth goes up, the smoke in the cooling chamber goes down, and the smoke in the superheater chamber goes down. The water cooling wall arrangement structure of the straw boiler is characterized in that membrane-type wall cooling walls are respectively arranged on the periphery of the hearth, the periphery of the cooling chamber and the periphery of the superheater chamber; the corresponding areas of the membrane-type wall cooling walls are as follows: a hearth water cooling wall, a cooling chamber water cooling wall and a superheater chamber water cooling wall; the hearth water cooling wall comprises a combustion chamber water cooling wall and a water cooling grate water cooling wall; and the combustion chamber water cooling wall is communicated with the water cooling grate water cooling wall.
