Description
The utility model is a kind of gas-fired furnace, particularly about a kind of thermal efficiency height, and heating gas heating furnace simple in structure.
Present hot coal steam stove, wastes energy so the thermal efficiency is low because energy utilization rate is low, and nearly 10,000,000 yuan of high every the cost of the complicated cost of equipment, and has cigarette to discharge.
The purpose of this utility model is: a kind of heating gas heating furnace is provided, and its thermal efficiency height, simple in structure, no chimney.
The technical solution of the utility model is: design a kind of heating gas heating furnace, it comprises body of heater, gas generating chamber, heating clamber, water circulation system, first and second air feed system, fire door elevating mechanism, coal mechanism, ash disposal mechanism, steam trap, it is characterized in that: gas generating chamber's side surface is with cyclic water jacket, cyclic water jacket is communicated with steam trap by circulating water pipe and return tube, and gas generating chamber is communicated with heating clamber.
Described gas generating chamber side surface has ignition furnace door and coal filling hole, and the side surface of all the other gas generating chamber all is connected with cyclic water jacket.Described gas generating chamber top is fixedly connected with steam trap, and steam trap is communicated with cyclic water jacket by 4 circulating water pipes and 4 return tubes.Be communicated with steam pipe between described steam trap and the air blast airduct.
The furnace bottom of described gas generating chamber is supported with movable grate, and movable grate is made handle with behaviour and is connected, so that deslagging at any time.Be connected with heat-insulation layer in the outer body of heater of described heating clamber, heat-insulation layer is sticking by clay brick, aluminosilicate refractory fiber, the diatomite insulating brick connects and composes.Described secondary wind economizer bank is fixed on around the heating clamber stove gate, and its port leads on the passage of gas generating chamber and heating clamber connection, and the another port is communicated with the air blast airduct.Described gas generating chamber is connected with explosion-protection equipment.
Characteristics of the present utility model are: because gas generating chamber's side surface of this heating gas heating furnace has the ignition furnace door and the coal filling hole of removing, remaining side surface all is connected with cyclic water jacket, adopt full water jacket, the high quantity of steam of the thermal efficiency big, be communicated with steam pipe between steam trap and the air blast airduct, it is many to produce coal gas H2.Secondary wind economizer bank is fixed on around the heating clamber stove gate, and its port leads on the passage of gas generating chamber and heating clamber connection, and the another port is communicated with the air blast airduct.Adopt secondary air channel that coal tar is all burnt, the heat height, smokeless, do not pollute, so this heating gas heating furnace structure is easy to be multiple functional, safe and reliable, cheap, only be 10% of cooled coal gas heating furnace cost.It is the firing equipment of environmental protection that this firing equipment removes flue dust.The overheavy firing of secondary wind makes the straight oily completing combustion of coal, eliminates the harm of the straight oil of coal, and has increased calorific value and saved energy.
The preheating of secondary wind makes furnace temperature improve 100～200 ℃ and economizes on coal 15%.Heating furnace furnace lining advanced design, and after having increased the alumina silicate heat-insulation layer, economize on coal 8%.Adopt heating gas directly to penetrate heating furnace than cooled coal gas energy-conservation 35%.Consumption coal 250Kg when this heating furnace steel per ton is heated to 1200～1300 ℃, steel coal ratio is 1: 0.25, reaches domestic state-of-the-art level.Manual movable grate can guarantee that coal evenly descends, and provides chemistry balanced reaction for oxidation reduction reaction layer.
The gasification of heating furnace is: after coal enters gas generating chamber, and through super-dry, destructive distillation layer, gasification layer, burning zone becomes waste residue at last and discharges.
The gasification layer is a coal gas redox reaction process, and promptly carbon and oxygen violent oxidation reaction take place and emits a large amount of heats:
CO
2Rising is by reducing zone generation reduction reaction:
The CO that it produced is the main component of coal gas, also has the water vapour of some also to participate in reaction:
The coal tar steam that the drying and carbonization layer produces, fuel gas and CO composition mists such as methane CH4 feed secondary wind at the road by heating clamber and reach overheavy firing.After gasification, the heat energy that the 1KG coal contains has the physics thermal energy storage of 65%～70% chemical energy and 8%～10% in coal gas, therefore the coal gas that produces in the mode that gasifies is sent into and is carried out the fuel factor height that the ratio of combustion reverberatory furnace obtains in the burner hearth, about fuel savings 20%-30%.The semiwater gas chemical composition is CO 25.5%, CO 27.5%, H2 13.5%, N2 52.6%, and H2 content is higher, and the caloric value of H2 is 3.5 times of carbon, has so just improved the fuel factor of stove.
The coal gasification heating furnace is to be finished by gas generating chamber and heating clamber combination.Except this two large divisions, also have steam trap, and water circulation system, a secondary air feed system, fire door, coal mechanism etc.In stove hall heat-insulation layer, adopt clay brick+aluminosilicate refractory fiber brick+sil-o-cel C12 simultaneously, can significantly reduce distributing of heat, reduced the loss of heat.This heating furnace, adopt gas generating chamber closely to link to each other with heating clamber, directly the heating gas that gas generating chamber produced is delivered to heating clamber, and feeding secondary wind reaches overheavy firing in leading to the passage of heating clamber, eliminate the purpose of flue dust, so both improve the calorific value of coal gas, reduced the thermal loss of carrying coal gas again, improved the heat utilization ratio of coal gas.
The main energy saving way of heating furnace.
1, full water jacket gas heating furnace adopts gas generator by a wind substitution steam, and its steam pressure is 0.04～0.07MPA, and steam and coal pyroreaction decomposite hydrogen, and the ratio of hydrogen is high more, and the fuel factor of burning is good more, improves the heating-up temperature in the stove.
2, reduce the heat loss of smoke evacuation, the exhaust gas temperature of heating furnace is up to 1000 ℃-1200 ℃, and the heat loss of smoke evacuation accounts for the 50%-60% of whole heat income, in order to save heat, coefficient of excess air is reduced to 1.1-1.2 by 1.4, the intake of strict control first and second.
3, reclaim smoke exhaust heat, and be used, adopt the air exchanging air to reclaim the heat that smoke evacuation is taken away.Because the employing of overheavy firing in gas-fired and the stove, the smoke evacuation burning condition forms, so stove significantly reduced the heat loss of smoke evacuation like this without chimney emission, reaches energy-conservation effect, rough estimates 15%-20% capable of saving fuel.
4, adopt best furnace lining structure and thickness.Furnace lining selects for use clay brick+aluminosilicate refractory fiber to glue+the diatomite insulating brick, and such furnace lining insulation construction makes general 200 ℃ of stove hall hull-skin temperature, is reduced to about 70 ℃ fuel savings 8%-12%.
