Abstract

A backfire bulk coal gasification normal pressure water boiler comprises a furnace body and a furnace body external part. The boiler body comprises an upper horizontal drum; the lower part of the drum is connected with a flue gas passage; the lower part of the flue gas passage is separated into a front part and a rear part through a lengthways isolating water wall, wherein the rear part is a combustion chamber and the front part is divided into an upper coal gas generating chamber and a lower open fire ignition area through a water-cooling grate; an anti-deflagration device is arranged at the upper part of the coal gas generating chamber; and the flue gas outlet of the boiler body is connected with an air inducing device outside the furnace body. Coal gas generated in the coal gas generating chamber performs inverse motion under the compulsive force of the air inducing device and is lit when passing through the open fire ignition area, so that the coal gas fully burns in the combustion chamber, heat quantity is fully released to heat a heating surface, and environment-friendly emission is realized. The flue gas enters into the horizontal drum through a flue duct, thereby realizing three return stroke flue gas flow.

Description

The backfire coal gasification normal-pressure hot-water boiler that looses
(1) technical field
The utility model relates to a kind of backfire coal gasification normal-pressure hot-water boiler that looses, and specifically relate to a kind of coal that will loose and transform and generate coal gas, and the normal-pressure horizontal hot-water boiler that acts as a fuel with this coal gas.
(2) background technology
Resource and environment are the human most thorny issues that faces at present, and outstanding behaviours is the quick consumption of resource and the resource contradiction between non-renewable, and human being's production is lived to the contradiction between environment damage and the Nature ecological balance.Traditional coal direct-burning boiler has caused the waste of coal resources and the pollution of atmospheric environment because of the poor efficiency of its energy and the fume emission that exceeds standard.Face the destruction day by day of the in short supply day by day and environment of resource, the change of coal-burning boiler is extremely urgent, and the utility model arises at the historic moment under this major premise.
(3) summary of the invention
The present invention is in order to solve the exceed standard problem of discharging of the low and flue gas of general coal-burning boiler rate of energy, and the utilization coal that will loose is converted into coal gas, reaches the purpose that improves fired coal combustion efficient, reduces smoke emissioning concentration by burning coal gas.
The technical scheme that adopts is:
The backfire coal gasification normal-pressure hot-water boiler that looses comprises the outer part of body of heater and body of heater.Its boiler body comprises: the horizontal drum in top, the drum bottom connects exhaust gases passes, two parts before and after the exhaust gases passes bottom is divided into by vertical isolation waterwall, aft section is the combustion chamber, previous section is divided into top gas generating chamber by water-cooled grate, the bottom naked light is lighted the district, and explosion-proof burning device is arranged at gas generating chamber top.The boiler body exhanst gas outlet is connected with the outside blower unit of body of heater.Under the power of enforcement effect of blower unit, realize reverse movement by the coal gas that gas generating chamber produces, light the district through naked light and lighted, fully burn in the combustion chamber then, fully release heat heating heating surface.
Above-mentioned explosion-proof burning device is that coal gas dredges when being used to stop air inducing at coal gas generating region top setting device.
The utility model reasonable in design, sufficient combustion, environment protecting is good, heating surface connection and reasonable arrangement heat utilization ratio height, simple and safe operation, suitable promoting the use of.
(4) description of drawings
Figure one is a side schematic view of the present utility model.
Figure two is front schematic view of the present utility model.
(5) specific embodiment
The reverse combustion type of the present utility model coal gasification boiler that looses comprises the outer part of body of heater and body of heater.Its boiler body (1) comprising: the horizontal drum in top (8), the drum bottom connects exhaust gases passes (11), two parts before and after the exhaust gases passes bottom is divided into by vertical isolation waterwall (6), aft section is combustion chamber (4), previous section is divided into top gas generating chamber (2) by water-cooled grate (9), the bottom naked light is lighted district (3), and explosion-proof burning device (5) is arranged at gas generating chamber top.Boiler body exhanst gas outlet (12) is connected with blower unit (10).Under the power of enforcement effect of blower unit, realize reverse movement by the coal gas that gas generating chamber produces, light the district through naked light and lighted, fully burn in the combustion chamber then, fully release heat heating heating surface, flue gas enters horizontal drum through flue, realizes three backhaul flue gas flows.

Claims (1)
