Description

Water combustion-supporting energy-saving fast-burning furnace

The utility model relates to a kind of water spray Combustion-accelerating stove devices.

At present, most coal-fired stove tools are combustion-supporting without other material, and it is slower then to get angry, about 600 ℃～700 ℃ of furnace chamber temperature, firepower a little less than.The combustion-supporting stove of some water, because its designs of nozzles problem to the furnace injection water vapour, service life and usefulness are relatively poor, the Position Design of its water vapor cover is unreasonable in addition, thereby make stove to burn could to spray water certain the time combustion-supporting, it is slower to get angry, and is not suitable for burning coal briquette or lump coal.

The purpose of this utility model is to design a kind of water combustion-supporting and energy-saving fast-burning furnace, utilize spray into after the water vapor in the furnace chamber combustion-supporting, thereby reach fast burning, energy-conservation effect.

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is the structural representation of the utility model spray vapour device

As shown in Figure 1, the utility model by water tank 1, water inlet pipe 2, control valve 3, water spout 4, spray orifice 5, furnace chamber 6, support 7, furnace shell 8, go up that vaporizer 9, steam guiding tube 10, tile 11, fire grate 12, spiral shell buckle 13, stove pin 14, blowoff valve 15, steam jet pipe 16, spray vapour lock 17, down vaporizer 18, heat-insulation layer 19, tube connector 20, connect valve 21 etc. and partly constitute, wherein go up vaporizer 9 and under vaporizer 18 be annular hollow.

As shown in Figure 1, during the utility model work coal is put on the fire grate 12 of furnace chamber 6, firing coal, owing to be the coal of 6 bottoms, first burner chamber, so burn one after the meeting, the madial wall of following vaporizer 18 will heating, and it is red-hot gradually, open control valve 3, water in the water tank 1 is flowed in the stove through water inlet pipe 2, because water tank 1 has certain height poor with water spout 4, so water can spray into the inwall of vaporizer 9, if the red-hot then water of this inwall will become water vapour, if this inwall is not red-hot as yet, then water flows to down the inwall of vaporizer 18 through tube connector 20, becomes water vapour after being heated, when last vaporizer 9 and following vaporizer 18 all red-hot, then adjustable metering valve 3, strengthen inflow, make vaporizer 9 reach vaporizer 18 co-operation down, produce more water vapour, the water vapour that produces flows to air jet pipe 16 through steam guiding tube 10, when water vapour produces morely, and will be ejected in the furnace chamber 6 by air nozzle 17 when reaching a certain amount of, water vapour resolves into hydrogen and oxygen after meeting the high temperature naked light, with regard to incendivity and combustion-supporting, spray vapour lock 17 makes progress jet the time, and the spray orifice 5 of last vaporizer 9 upper sides also sprays vapour in furnace chamber 6, the firepower of furnace chamber 6 internal upper parts is also strengthened.Control the size that injection flow rates can be regulated firepower in the furnace chamber 6 by control valve 3.Spray vapour lock 17 is positioned on the steam jet pipe 16, and it is the convex hollow body that raises up, and there is little jetted hole on the top of projection, because spray vapour lock 17 is protruding, so the coal ash that burnt on the fire grate (slag) can not be blocked jetted hole and influence spray vapour effect quickly when falling.Downside of the present utility model is provided with fire door to be opened/closed, opens fire door and colludes steam jet pipe 16, and it just can produce outside the stove for the axle center by spiral shell button 13, and open blowoff valve 15 and can clean steam jet pipe 16 inside, and the surface of cleaning steam jet pipe 16 and spray vapour lock 17.Because the coal in the furnace chamber 6 is bottom-up burning, the following vaporizer 18 of institute produces steam earlier, combustion-supporting through ejection such as spray vapour lock 17 grades, so it is very fast to get angry in the stove, because coals are more thicker in the furnace chamber 6,, there has been spray orifice 5 just can make combustion-supporting effect better from top spray vapour so jet combustion-supporting effect is relatively poor from the bottom, firepower is more violent, and makes the utility model can be suitable for all kinds of moulded coals, coal briquette and lump coal.

After opening some apertures on the madial wall of vaporizer 18 under last vaporizer 9 in the utility model reaches, can increase spray vapour area, combustion-supporting effect is better.

But the utlity model has that quick combustion, firepower are violent, the high temperature adjustment of fire temperature, energy-conservation, characteristics such as applicability is strong, the life-span is long.
