The utility model is characterized in that the upper part of the stove casing is fixedly provided with a metal tube (11) for sensing temperature variation; the inner part of the metal tube is provided with an adjusting controller which is composed of an air inlet pipe (8), a movable air door (10) and a U-shaped heat sensitive metal sheet (9); the upper part of the hearth is also provided with a cavity which is communicated with the outside by a secondary air inlet pipe (2). The coal-saving stove has the advantage of visible energy-saving effect, and the adjusting control device can be widely used in a single-hole or a multi-hole honeycomb briquette stove.

Description

Self controllable coal-saving stove

The utility model belongs to the stove and accessory technical field.

Now, generally its banking of the honeycomb briquette stove of Shi Yonging (single hole stove, three hole stoves and porous stove) realizes that by cutting out fire door the gap when closing as if fire door is inappropriate, then causes flame-out or stove coal after-flame.

When providing a kind of banking, the purpose of this utility model can save coal-fired auto-control coal-saving stove.

The purpose of this utility model is achieved in that it comprises furnace shell, burner hearth, fire door, the stove tooth, it is characterized in that: the metal cylinder of burner hearth fixture temperature sensor variation effect between furnace shell, the bottom has an air intake conduit to extend to fire door (13), there is modulator metal cylinder inside, modulator is by blast pipe, movable air door, ∪ type thermometal sheet constitutes, blast pipe extends outside the furnace shell, movable air door links with form and the modulator blast pipe that activity connects, ∪ type thermometal sheet one end is welded on the modulator blast pipe, and the other end touches mutually with movable air door; Upper furnace has a cavity, and empty thorax is communicated with secondary wind inleting tube with outside.

The utility model is on probation through 5 wheat harvesting periods, and its banking is reliable and stable, the banking time long (keep two and half coals in the stove, but banking 30 hours), uses easy to operationly, and quick combustion when normally using, firepower are violent.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing is the utility model structural representation.

1 boiler face lid, 2 secondary wind inleting tubes, 3 burner hearths, 4 furnace shells, 5 stove teeth, 6 flue seats, 7 base plates, 8 modulator blast pipes, 9 ∪ type thermometal sheets, 10 movable air doors, 11 sensible heat tubes, 12 banking air intake conduits, 13 fire doors.

The banking device for automatically regulating is by sensible heat tube 11, and parts such as banking blast pipe 12 and modulator are formed.Sensible heat tube 11 is to be fixed on the furnace shell on stove top, and is approaching with hearth wall, and its effect is to obtain the heat in the stove and place modulator, and the height of temperature changes with variations in temperature in the stove in the tube.The below of sensible heat tube 11 has a certain size hole, and is connected with banking air intake conduit.Banking air intake conduit leads to the inboard of fire door by the inwall of furnace shell.Modulator is by blast pipe 8, movable air door 10, ∪ type thermometal sheet 9 one ends are welded on the modulator blast pipe 8, the other end touches mutually with movable air door 10, and it has and varies with temperature and the characteristics of modification, and its effect is to close and regulate modulator air door 10 sizes.The size that modulator air door 10 is opened changes with variation of temperature, and temperature is lower, and it is open bigger, and temperature is higher, and it is open littler, until closing.Modulator is mounted in the sensible heat tube.

When the temperature when banking was low, the air door 10 of modulator was open, and the air during its banking advances the stove route and is: go out modulator air door 10 and enter the sensible heat tube through modulator blast pipe 8, advance banking air intake conduit 12 to fire door 13 inboards by the sensible heat tube.After fire door 13 was opened, stove fire increased gradually and furnace temperature is increased, and the temperature of sensible heat tube is also along with increasing, the ∪ type thermometal sheet 9 of the modulator modification purse up that is heated, and the air door 10 of modulator also diminishes gradually, until closing.Coal stove in use because the big temperature height of stove fire, modulator is closed condition.When stove is stopped using and after banking cuts out fire door 13, except a spot of gas leakage, do not had air to enter in the stove.But in a bit of time at banking initial stage, also exist oxidation reaction, oxidation reaction is during this period of time closed oxygen and carbon reaction generation carbon dioxide in the residual air in the stove of back from: fire door, steam in the stove decomposes the carbon monoxide that the back produces, and the carbon dioxide in the stove contacts with red-hot carbon and is reduced into carbon monoxide.Gases that these reactions generate become furnace gas and discharge out of the furnace with slower speed, and in the process that discharges out of the furnace, carbon monoxide is wherein met oxygen and burnt at fire door, sends blue flame.Afterwards, in the quite a long time,, be not have oxidation reaction substantially in the stove because the furnace temperature height can not be opened the air door of modulator.Owing to there has not been exothermic oxidation reaction.Stove fire is gradually by prosperous deepening, and furnace temperature also descends gradually, when furnace temperature drops to a certain degree, the thermometal sheet 9 of modulator because of the reduction of temperature gradually modification open, with air door 10 ascending the opening gradually of modulator, up to the stove fire balance till.Or because the rise and fall of the rise and fall of stove fire and furnace temperature are asynchronous, exist the reason of regular hour difference, make stable within the specific limits descending of the air door of modulator, under the ascending frequent transitional states, stove fire is saltus step within the specific limits also.

Claims (1)

1, a kind of auto-control coal-saving stove, it comprises furnace shell, burner hearth, fire door, the stove tooth, it is characterized in that: the metal cylinder (11) of burner hearth fixture temperature sensor variation effect between furnace shell, the metal cylinder bottom has an air intake conduit (12) to extend to fire door (13), there is modulator metal cylinder (11) inside, modulator is by blast pipe (8), movable air door (10), U type thermometal sheet (9) constitutes, blast pipe (8) extends outside the furnace shell, movable air door (10) links with form and the modulator blast pipe (8) that activity connects, and U type thermometal sheet (9) one end is welded on the modulator blast pipe (8), and the other end touches mutually with movable air door (10); Upper furnace has a cavity, and empty thorax is communicated with secondary wind inleting tube (2) with outside.
