Description

Civilian composite purification coal furnace

The utility model relates to a kind of civilian composite purification coal furnace, belongs to the coal combustion technology field.

Coal is the natural solid fuel of a kind of carbon containing, moisture, ash content and multiple hydro carbons, and coal combustion is meant fuel and airborne oxygen heat release combination reaction.Coal is met thermal decomposition and is produced gaseous state volatile matter and fixed carbon in combustion process, combustible under oxygen abundance and hot conditions in the volatile matter and fixed carbon burning.Yet the volatile matter that traditional commercial coal stove is separated out in combustion process, the overwhelming majority and unburneds and escaping in the atmosphere had not only wasted energy but also contaminated environment.It is convenient no doubt to burn gas, and phosphorus content generally reaches about 30% in the slag of gas and manually make, and adds the thermal power transfer loss of upper gasification, gas process, and its integrated heat efficiency is lower.

The utility model is a kind of composite purification coal furnace that is integrated by with coal part gasification furnace and solid combustion furnace accretion, combustible gas and fixed carbon is burnt reach clean combustion in a stove, improves that heat is imitated, pollution abatement, and the purpose of effectively utilizing.

The utility model comprises fuel combustion and heat energy utilization two parts: establish on one young in body of heater, the flue that the bottom is big, and be divided into two sections: epimere is the gas fuel burning chamber, hypomere is the fixed carbon burning bed, between upper and lower two sections coal filling hole is arranged, have secondary air duct to feed the epimere combustion chamber around the hypomere flue through secondary air hole.Flue bottom be a grate, and its underpart is air-distributing chamber and communicates with first and second air channel and air door, is grey slag bucket bottom the air-distributing chamber.Around fire door, annular flue arranged, draw flue, floss hole communicates.The cooker placement fire that can adapt to variety classes, specification in the upper end of annular flue for the annular bell group of size coupling.

Warming adopts the osculum boiler, and its taper inwall constitutes the epimere flue and is connected with the hypomere flue.Boiler has the external radiator of inlet tube and outlet tube to constitute the closed cycle water-heating system; Non-heating period can take down boiler changes shape, the big or small osculum flue suitable with it, is beneficial to the heating system maintenance.Establish boiler in the flue side and absorb waste heat.Between each assembly in the furnace shell is insulating, and 4 universal wheels are installed in the furnace shell bottom.

The utility model is compared with prior art: ventilate proper, support sufficient, sufficient combustion, the speed of getting angry is fast, intensity of fire is high and effective utilization, simultaneously energy savings, pollution abatement.

Below in conjunction with accompanying drawing embodiment is described further:

Fig. 1, be the front view of civilian composite purification coal furnace.

Fig. 2, be the vertical view of civilian composite purification fire coal.

As shown in Figure 1 and Figure 2, the utility model is by metal furnace shell (13), cast iron annular bell group (1), osculum boiler (20), refractory material lower furnace (16), grate (10), heat-barrier material air-distributing chamber formations such as (11).Wherein annular bell group (1), annular flue (4), draw flue (5), floss hole (23) communicates.The taper inwall of osculum boiler (20) is connected with lower furnace (16), and coal filling hole (6) and coal bunker (7) are arranged therebetween.Osculum boiler (20) constitutes the closed cycle water-heating system with the external radiator of inlet tube and outlet tube (21); Non-heating period can take down osculum boiler (20) and change and its shape, sizable refractory material flue, so that the maintenance of heating system.Lower furnace (16) is established secondary air duct (17) on every side and is constituted ventilating system with secondary air hole (19), air-distributing chamber (11), grey slag bucket (12), an air channel (9), air door (8).The flue side is established metal and is heated water tank (22) and pass through mutually with coal filling hole (6).4 universal wheels (14) are installed in furnace shell (13) bottom.

When using, adding fuel from coal filling hole (6) is subjected to thermogenetic fuel gas to enter upper combustion chamber (3) and the mixed combustion of secondary wind, fixed carbon in the burning bed (15) and a wind even contact burning that enters by grate (10), form gas phase, solid phase compound combustion, the heat energy that is discharged is effectively utilized by cooking, heating, hot water.It can the burning type burns, coal looses.Can produce the product of different size, class as required, extensively be suitable for family, catering trade use, realize clean combustion of coal.
