Abstract
The invention discloses a chain-typed coal gasification normal pressure hot water environmental protection boiler, comprising three hearths and three arc walls. The tops of the hearths are connected with three arch crowns in an enclosing way forming a whole body. The coal is gasified in the hearth of the preheating combustion furnace, and is burned in a high temperature smoke abatement combustionburn-out area. The flame burned out is reflected and burned in a convection radiation combustion burn-out area. The smoke is discharged into the smoke pipe of a top boiler drummer through the hole arranged at the top of the third reticular radiation arc wall the top arc of which is connected with an inclined and long arch. The invention is designed reasonably, arranges the heating area and chain-typed effective grate area scientifically, can heat evenly, can fully absorb the heat in the hearth by a heating tube bundle, can transfer the heat quickly, burns fully, does not produce black smoke, greatly improves heat efficiency, saves energy, is convenient to be operated, has a high coal gasification ratio, is applicable to various coals, and is suitable to be used in the places of factories,mines, government agencies, schools etc. which adopt non-concentrated heating supply method.
Description
Technical field
What the present invention relates to is boiler, and concrete is chain type fire coal gasfication atmospheric hot-water environmetnal protection boiler.
Background technology
The boiler that uses divides with regard to the fuel that adopts at present coal stove, oil oven two big classes, because it is coal-fired serious to air and environmental pollution, a lot of coal-burning boilers have adopted coal-fired gasification technology, have of the pollution of the coal smoke of dust with minimizing to air, yet the gasification coal-fired boiler that uses has only a burner hearth now, the fuel gas that fire coal is gasificated into can only be in the burner hearth intermediate combustion, its heat also only concentrates on the subregion in the middle of the burner hearth, there are some heats not to be fully used, the tube bank of not being heated absorbs, just very fast discharge from chimney has caused the loss and the waste of the energy, this also is the existing main cause that awaits further to increase substantially with the gasification coal-fired boiler thermal efficiency, and used boiler is to coal smoke simultaneously, yet there be not slap-up putting in place in the processing of lime-ash.
Summary of the invention
The objective of the invention is in order to solve the present plain cylindrical furnace thermal efficiency low, flue dust greatly problem such as the suitable pollution of environment structure is provided a kind of energy-saving and cost-reducing, the thermal efficiency is higher, does not have the chain type fire coal gasfication atmospheric hot-water environmetnal protection boiler of flue dust during burning.
The technical scheme that adopts is:
Chain type fire coal gasfication atmospheric hot-water environmetnal protection boiler comprises body of heater, preheated burning burner hearth, high temperature smoke elimination burning burning-out zone, the netted arch wall in top, first road, top, second road sealing radiation arch wall, top, the 3rd road arch and the oblique long netted radiation arch wall that links to each other that encircles; Described upper of furnace body is provided with a upper drum, the top of upper drum is provided with manhole, outlet pipe, atmospheric communicating pipe, the inside of upper drum is equiped with the tube bank of being heated, the bottom of body of heater is provided with the air blast interface, the rear wall of body of heater is provided with return pipe, blow-off pipe and shoot door, the front of body of heater is provided with coal bunker, and its design feature is:
The front end at body of heater middle part is provided with pre-heat radiation arch, and the back of pre-heat radiation arch is provided with the netted arch wall in top, first road, is provided with the preheated burning burner hearth between netted arch wall in top, first road and pre-heat radiation arch; Sealing radiation arch wall in top, second road is set in the back of the netted arch wall in top, first road, between netted arch wall in top, first road and top, second road sealing radiation arch wall, be provided with high temperature smoke elimination burning burning-out zone, be provided with top, the 3rd road arch and the oblique long netted radiation arch wall that links to each other that encircles in the back of top, second road sealing radiation arch wall, top, the 3rd road arch links to each other with oblique long arch and is provided with convection current radiation combustion zone between netted radiation arch wall and top, second road sealing radiation arch wall, top, the 3rd road arch is set to radiation by slag after-flame burner hearth arch with oblique long bottom of encircleing the netted radiation arch wall that links to each other, and radiation is connected with the rear wall of body of heater by the end of slag after-flame burner hearth arch.
Above-mentioned pre-heat radiation arch, the netted arch wall in top, first road, top, second road sealing radiation arch wall close with the oblique long last closedtop that encircles the netted radiation arch wall that links to each other with top, the 3rd road arch and link into an integrated entity.
The above-mentioned netted arch wall in top, first road is respectively arranged with a plurality of holes with top, the 3rd road arch with oblique long top of encircleing the netted radiation arch wall that links to each other.
The bottom of above-mentioned body of heater is provided with chain furnace grate.
Working procedure:
See that Fig. 1-2 is described, coal-fired from last coal bunker threading, and deliver on the chain furnace grate, along with being transported to the preheated burning burner hearth with fire coal, the transmission of chain furnace grate carries out coal-fired gasification, fuel gas that generates and fugitive constituent from the hole on netted arch wall top, top, first road and down arch enter into eliminate smoke burning burning-out zone and burn fully with the oxygen mix that air blast is entered and heat the tube bank of being heated of high temperature, and arch enters convection current radiation combustion zone, the 3rd road convective burning its is forced unburnt fugitive constituent warp in hyperthermia radiation burning back by air blast, air inducing under.Because of the eliminate smoke top of burning burning-out zone and top, second road sealing radiation arch wall wall of high temperature is totally-enclosed arch wall, radiation pyrotechnics can only pass through from the following arch of top, second road sealing radiation arch wall.Because of entering convection current radiation combustion zone by the part fuel gas, the convective flow of gas proceeds burning, after-flame in the burning, top, the 3rd road arch is set to oblique radiation by slag after-flame burner hearth arch with the oblique long netted radiation arch wall bottom that links to each other of encircleing, being convection current radiation combustion zone convective burning in flame reflected back the 3rd burner hearth with after-flame, the pyrotechnics after the burning is entered in the smoke pipe of upper drum with the hole that oblique long top of encircleing the netted radiation arch wall that links to each other is provided with by top, the 3rd road arch.Lime-ash behind the coal-fired gasification is transported to shoot door by chain furnace grate, and removes from shoot door.
Overall construction design of the present invention is reasonable, the science that the effective grate area of heating surface area and chain-type is arranged, and coal-fired gasification is fully burning in two burner hearths, is heated evenly, and the temperature of burner hearth is heated, and tube bank is abundant to be absorbed, and it is quick to conduct heat, and sufficient combustion does not produce black smoke.
Need to prove: under the prerequisite that does not change the principle of the invention and design, change of having done or distortion all belong to protection scope of the present invention.
