Description

Domestic coal-burning heating stove

The utility model relates to a kind of domestic heating coal furnace.

Northern area domestic heating coal furnace also has a kind of commercially available iron stove except that a kind of fixing brick formula stove, the two mostly adopts hot wall or chimney to be embodied as the purpose of indoor heating.The structure of this heat supply mechanism is a kind of backward heating system, and its thermal efficiency is low, energy consumption is high and seriously polluted.A kind of improved domestic heating coal furnace is to be shaped on water jacket to provide hot water for device at indoor cooling system around body of heater and chimney.This stove characteristics that have water jacket are that the thermal efficiency is higher, energy consumption is low, pollution is less etc.But this stove perishable and service life is short and system cost is higher.

The purpose of this utility model is that disclosing a kind of is the design of the heating coal furnace of indoor heating in the heat air delivery mode.

For achieving the above object, the technical measures taked of the utility model are that a structure that produces hot blast and heat air delivery will be arranged on body of heater.For this reason, this stove mainly contains formations such as body of heater, burner hearth, flue, flue, induced duct, thermal-collecting tube, fire expelling cover, flame-gathering cover, temperature-increasing box and block, exhanst gas outlet and hot-blast outlet, the key of its structure is that one is built-in with the burner hearth of flue and the block of vertically-arranged one temperature-increasing box joins, and one of the flue of device in block is terminated at burner hearth and the other end is connected to the fire expelling cover that vertically-arranged on device its in temperature-increasing box has the taper thermal-collecting tube, and the osculum end of thermal-collecting tube inserts the flame-gathering cover that is shaped on exhanst gas outlet and with placing its end face to be shaped in the temperature-increasing box of hot-blast outlet.Now be further described as follows.The cone barrel of burner hearth central means of a common coal furnace and be seated in flue on the grate, coal-fired in the flue internal combustion, for making sufficient combustion, connect on the courage wall and be equipped with the induced duct that passes furnace body wall more than 4, the effect of this pipe is to inhale fresh air outside stove with combustion-supporting burning.Annular gap between furnace wall and the furnace body wall is a space that produces hot gas.Device one termination is gone into the flue of burner hearth in the block that joins with burner hearth, and the other end inserts a box-like fire expelling cover, the last vertically-arranged of this cover has device its big end in temperature-increasing box, and small end is at last taper thermal-collecting tube descending, and thermal-collecting tube osculum end inserts its top and is shaped on the flame-gathering cover that exhanst gas outlet is a curve.So, flue--has constituted another space that can produce hot gas and communicate with aforesaid that hot gas space between fire expelling cover--thermal-collecting tube--flame-gathering cover and block and temperature-increasing box inwall.In order to be incubated, the wall of temperature-increasing box and block contains heat-barrier material.In order to realize the purpose to indoor heating, lower furnace portion is connected to airduct, and this airduct connects a typhoon machine.When blower fan turns round, the air that its drum advances,----thermal-collecting tube--around flame-gathering cover--and by each heating pipe of outlet input has reached and has been the purpose of indoor heating fire expelling cover along flue with the hot gas that produced in aforementioned two spaces (and will constantly produce hot gas).In the time of as the domestic heating stove, general all double as life is daily, heats up water as culinary art etc.Therefore, be equipped with stone or metal plate for standing a stove on as a precaution against fire etc. on this stove boiler face for aforementioned applications.

The design that the utility model proposes has the characteristics of quick heating, efficient height through test.For example in the room that an area is 55 square meters, use a middle-size and small-size coal stove, using a merit tool is 2750 rev/mins blower fan as 100W, rotating speed, only coal-fired 4KG and can make at 40 minutes that room temperature is clean to rise 20 ℃, its index surpasses general coal furnace and water-jacket typ heating stove.The boiling water of boiled about 60KG simultaneously also in above-mentioned nearly 40 minutes temperature-rise period.Only above two meters can be economized on coal more than 40%.Its this, through relevant test, the blackness that this fire grate is put flue dust is that the Lin Geman index also is lower than other coal furnace.The person, also more simple and convenient from installing and using aspect such as maintenance, its weak point is to need device one typhoon machine and consume certain electric energy.This stove is simple in structure and do not have corrosion than the water-jacket typ heating stove, has certain use value in certain areas.

Figure of description is disclosed to be the broken section structural representation of a kind of embodiment of the utility model.

For implementing such scheme, existing a kind of more suitable embodiment of accompanying drawings.Body of heater 1 and burner hearth 5 usefulness steel plates roll back welding, and the two can be made into isometrical or not isometrical, and not isometrical as shown in the figure then the two junction surface is connected with the awl tube and as the part of burner hearth.Grate is formed between the composition surface of body of heater and burner hearth.The flue of firing with refractory material 10 places burner hearth, and the hole (corresponding therewith hearth wall also is shaped on 4 holes to place induced duct 6) of 4 induced ducts of prefabricated installation is arranged on the courage wall.As other stove, suitable location at body of heater and burner hearth is shaped on ash door 2, slag notch 3, coal filling hole 4 respectively, the corresponding hearth wall upper shed of three is to connect system block 11 therewith, and will insert in the thorax with the flue 7 of panel beating simultaneously, flue 7 and fire expelling cover 12 and thermal-collecting tube 13, flame-gathering cover 15, exhanst gas outlet (curve) 16 all connect it with steel plate with panel beating.The wall of block 11 and casing 14 is to make behind the filling mineral wool between the sheet metal, and is integral with screw attachment, connects on the top of casing 14 to be shaped on two hot-blast outlets 17 that are the curve shape with panel beating.Be constant output hot blast, side joint is put airduct 9 behind burner hearth bottom, and the air blast 8 of this Guan Yuyi platform power 100W joins.During use, on two hot-blast outlets 17, connect and put the warm-air pipe that leads between heating and get final product.
