Abstract
The utility model provides a combustion furnace structure of a biomass combustion engine. A combustion furnace is provided with a reciprocating fire grate and a double-layer heat preservation jacket structure in a matched mode, the combustion furnace is sequentially provided with a fireproof pouring layer, a heat preservation jacket layer and a metal outer cylinder from inside to outside, and the heat preservation jacket layer is a double-layer jacket layer and is sequentially provided with a water cooled jacket layer and an air cooled jacket layer from inside to outside; a combustion chamber and a settling chamber are arranged in the combustion furnace, the reciprocating fire grate is arranged between the combustion chamber and the settling chamber, the reciprocating fire grate is composed of a movable fire grate and a fixed fire grate, one side of the combustion furnace is provided with a burner port, and the other side of the combustion furnace is connected with a feeding system and an air supplying system. The continuous movements of the reciprocating fire grate enable the generated coke to be eliminated to the settling chamber in time, the coking hidden trouble is avoided, the number of manual decoking times is reduced, labor intensity is relieved, the operation cost is lowered, and the double-layer heat preservation jacket structure is beneficial to heat preservation of a furnace body and improvement on the combustion efficiency.
Description
Technical field
The utility model belongs to combustion apparatus field, relates to a kind of combustion furnace structure of biomass combustion machine, particularly a kind of reciprocal grate and jacket structured combustion furnace of double-layer heat insulation of disposing.
Background technology
Biomass combustion machine is a kind of environmental protection combustion apparatus taking biological particles as fuel, its core texture parts are combustion furnaces, the design of combustion furnace is most important to improving efficiency of combustion, and the combustion furnace of existing biomass combustion machine exists the problem that coking phenomenon is serious, efficiency of combustion is low.
Summary of the invention
The purpose of this utility model is, overcome the deficiencies in the prior art, a kind of combustion furnace structure of biomass combustion machine is provided, a kind of reciprocal grate and jacket structured combustion furnace of double-layer heat insulation of disposing is specifically provided, this combustion furnace structure can reach better anti-coking effect, effectively improves the efficiency of combustion of biomass fuel.
The utility model solves the technical scheme that its technical problem adopts: a kind of combustion furnace structure of biomass combustion machine, it is characterized in that: described combustion furnace is followed successively by fire-resistant LIFT, thermal insulation clamp jacket layer and metal outer cylinder from inside to outside, in described combustion furnace, be provided with combustion chamber and expansion chamber, described expansion chamber is arranged on the below of described combustion chamber, between described combustion chamber and expansion chamber, be provided with reciprocal grate, one side of described combustion furnace is provided with nozzles, and described combustion furnace opposite side is connected with feeding system and supply air system.
Preferably, described thermal insulation clamp jacket layer is double layer jacket structure, is followed successively by from inside to outside water-cooling jacket layer and air-cooled chuck layer, and described air-cooled chuck layer is connected with supply air system.
Preferably, described reciprocal grate is made up of movable fire grate and fixed grate.
The beneficial effects of the utility model have: (1) arranges reciprocal grate between combustion chamber and expansion chamber, the continuous reciprocating motion of fire grate makes the coking producing can be scavenged in time expansion chamber, has avoided coking hidden danger, reduces artificial coke cleaning number of times, reduce labour intensity, saved operating cost; (2) double-layer heat insulation is jacket structured is conducive to furnace insulation and improves efficiency of combustion, water-cooling jacket connection recirculated water plays the object of furnace insulation, and air-cooled chuck one side connects supply air system, and opposite side connects nozzles, cooling air forms rotary wind in nozzles exit, contribute to the raising of flame temperature.
