Abstract

The utility model relates to a household coal-burning heating furnace. The utility model is characterized in that a furnace chamber is divided into a high temperature and a low temperature furnace chambers by a reflecting board; a rotational flow fume gas pipe is arranged on the water jacket around the reflecting board; an annular flue which is communicated with a fume exhaust opening is arranged on the circumference of the low temperature furnace chamber; a furnace grate is movable; a movable clinker-removing shovel is arranged between the furnace grate and a furnace core. The utility model has the advantages of good combustion effect, high heat exchange efficiency, small heat loss, function regulation and simple and convenient operation.

Description

Residential coal combustion high efficiency and multi-function heating stove
The utility model relates to a kind of domestic briquet stove.
Common coal stove generally is made of body of heater, flue, grate and burner hearth, and the heat energy utilization rate is low.A kind of heating stove of Tsing-Hua University's research and development, between flue and body of heater, water jacket is set, utilize flue to conduct heat heating water in the heating water jacket, the heat abstractor of high-temperature-hot-water being sent into the room carries out heating, and the high-temperature flue gas of flue burning rises to upper furnace and enters exhaust opening then and discharge outdoor by chimney.Though this kind stove thermal efficiency is higher,, because of water jacket is arranged on the flue outside, reduced the flue ignition temperature, fuel can not fully be burnt.In addition, owing to adopt traditional purge mode of slagging tap, need press from both sides out the interior hot coal of stove earlier during last coal, both inconvenience, loses heat again.
The purpose of this utility model is to provide a kind of thermal efficiency height, heat little, the easy and simple to handle multifunctional household coal heating stove that scatters and disappears.
The technical solution of the utility model is: burner hearth is separated into high-temperature burner hearth and low temperature burner hearth by reflecting plate, on the water jacket around the reflecting plate, the eddy flow fume pipe is set, high-temperature burner hearth and low temperature burner hearth are communicated, the low temperature burner hearth around annular flue be set communicate with exhaust opening; The movable grate of grate for moving up and down; The activity shovel of slagging tap is set between flue and grate, and pulling can make fire coal and cinder on the grate separate when slagging tap the activity shovel.
The utility model combustion efficiency is good, flue portion temperature height, and sufficient combustion, the high-temperature burner hearth part is fully burned fuel gas under the reflecting plate heat radiation; The heat exchanger effectiveness height, furnace heating surface is big, and flue gas flow is long, and heat exchange is abundant, and heat loss due to exhaust gas is little, and the heating of heating water is fast; Heat scatters and disappears little, and closed deashing is slagged tap, and avoids fuel to press from both sides out the heat loss that folder advances.
The utility model also has function adjusting, advantages of simple operation.
Fig. 1 is the utility model structure cross-sectional schematic;
Fig. 2 is that movable grate function is regulated decomposing schematic representation.
Below in conjunction with description of drawings most preferred embodiment of the present utility model.
As shown in Figure 1, the utlity model has body of heater 15, flue 14, movable grate 19 and burner hearth, burner hearth is separated into high-temperature burner hearth 9 and low temperature burner hearth 7 by reflecting plate 8, on the water jacket 13 around the reflecting plate eddy flow fume pipe 12 is set, and high low temperature burner hearth is communicated.Around low temperature burner hearth 7 is annular flue 11, is provided with porous floss hole 10 between low temperature burner hearth and the annular flue, and the top of low temperature burner hearth is stove cover plate 6, and annular flue top is furnace panel 5.The flue gas of high-temperature burner hearth enters the low temperature burner hearth by eddy flow fume pipe 12 and discharges outdoor by exhaust opening 4 after porous floss hole 10 enters annular flue.Movable grate 19 connects tooth bar 18, driving tooth bar by adjusting gear can make grate move up and down in the flue bottom, below the stove seat board 21 of flue, be provided with the activity shovel 20 of slagging tap, one of the activity of slagging tap shovel is stretched out outside the body of heater, and spurring the activity shovel of slagging tap can separate fire coal in the flue and the cinder on the grate.Also be provided with water channel between body of heater and hearth water sleeve, water advances from heating return pipe 2, goes out from heating outlet pipe 3.
Body of heater lower inner of the present utility model is provided with dreg scraper 1, when the slag on the grate goes downwards to the dreg scraper position, stirs dreg scraper and cinder can be dialled in the grey slag bucket of below.
As shown in Figure 2, movable slag tooth bar 18 of the present utility model is meshed with adjusting gear 16, and adjusting gear is connected with regulating handle 17 by axle.Rotate regulating handle, make adjusting gear drive tooth bar and move up and down, i.e. drive activity grate moves up and down.When grate was descending, the fire coal in the flue was also toward falling, when after-flame coal when falling certain distance, slag tap activity shovel of twitch makes it that fire coal and cinder are separated, movable slag is moved down again, stir dreg scraper, the cinder that is about on the grate is dialled in the grey slag bucket of below.And then rotate and transfer lower handle, make on the movable grate and move, to take out and leave the movable shovel of slag, the fire coal in the flue promptly drops on the grate.
