Embodiment Construction

[0018] As shown in the figure, an inverted firing boiler includes a boiler body wrapped by a furnace wall 1 and a bracket 2 for supporting the boiler body. The furnace wall 1 has a double-layer structure, and the space formed by the double-layer furnace wall is a water storage room. 3. A plurality of water pipe interfaces can be provided on the furnace wall. The boiler body is divided into a combustion chamber 4 and a heat collection chamber 5 by the furnace wall. The combustion chamber 4 and the heat collection chamber 5 are arranged horizontally, and through the The fire passage 6 is connected, and an air inlet 7 is arranged on the furnace wall on one side of the combustion chamber 4, and the air inlet 7 is set correspondingly to the fire passage 6. A hopper 8 is arranged above the combustion chamber 4, and the feeding port of the hopper is connected with the combustion chamber. The fuel automatically falls into the combustion chamber by gravity, and a fire grate 9 is arrange...

Abstract

An inverted burning boiler comprises a boiler main body and a bracket, wherein the interior of the boiler main body is divided into a burning chamber and a heat collecting chamber by a boiler wall; the burning chamber and the heat collecting chamber are transversely arranged and communicated with each other through a flame path; an air inlet is formed in the furnace wall on one side of the burning chamber; the air inlet is arranged corresponding to the flame path; a material hopper is arranged above the burning chamber; a material falling opening of the material hopper is connected with the burning chamber; a fire grate is arranged in the burning chamber; a material falling region is formed on the furnace wall at the bottom of the heat collecting chamber; a plurality of heat radiation tubes communicated with a water storage chamber are formed in the heat collecting chamber; an air exhaust opening is formed in the furnace wall on one side of the heat collecting chamber; and the air exhaust opening is connected with a smoke exhaust pipeline. The inverted burning boiler provided by the invention has the advantages of low fuel requirement, convenient filling mode, convenience for furnace slag cleaning, durable fire grate, very sufficient fuel burning and high heat utilization rate; therefore, the environment pollution caused by straw burning in rural areas is preferably improved.

Description

technical field [0001] The invention relates to a boiler capable of burning various fuels such as straw and wood, in particular to a backfired boiler. Background technique [0002] As coal resources become less and less, the utilization of straw, waste wood and combustible garbage is not widespread. How to use these straws, waste firewood, and combustible garbage is a big issue. At present, boilers that can use straw, wood and other fuels have higher requirements on materials. For example, the gasification furnace has high requirements on the humidity and size of the firewood fuel, and has disadvantages such as troublesome waste cleaning. Another example is biomass boilers, which require the use of biomass fuels, high fuel costs, and high equipment costs. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a backfiring boiler, which has the advantages of low fuel requirement, convenient fi...
