Description

Energy-conservation stove

It is main domestic energy-saving stove that the utility model relates to a kind of coal combustion, and the spy relates to a kind of energy-conservation stove that produces combustion-supporting gaseous mixture device that has in addition.

Along with the fast development of Chinese national economy, energy shortage has been the task of top priority.For energy savings, people have found out multiple way.Therefore, the energy-saving stove of various ways also arises at the historic moment.With regard to existing stove and accessory, be broadly divided into two classes: a class is to be the energy-conservation stove of purpose with the combustion rate that improves fuel, this type of stove and accessory adopts repeatedly the mode of return air more, try hard to make fuel combustion complete, though this can improve the thermal efficiency, reach purpose of energy saving, but complex manufacturing technology mostly, cost is also high; Another kind of is to be the energy-conservation stove of purpose with the utilization rate that improves heat, and this type of stove and accessory is provided with polytype water tank more, and can the heat so that abundant absorption has produced though this can improve the utilization to heat energy, fully burn attention inadequately to fuel mostly.

In view of the deficiencies in the prior art, the purpose of this utility model is a kind of simple in structure, energy-conservation stove that produces combustion-supporting gaseous mixture device that has that can make full combustion of fuel of design.

This energy-conservation stove partly is made up of device of shell, chimney, stove plate, burner hearth, fire grate plate, grey chamber, fire door, footing and the combustion-supporting gaseous mixture of generation etc.Burner hearth places on the fire grate plate, and is made of upper furnace and lower hearth; Fill the metal composites of loose oxide based on iron and/or iron in the enclosed cavity that forms between the inside and outside wall of lower hearth, the top of its outer wall is equipped with the superheated steam bend pipe and is stretched to the bottom of fire grate plate and parallel with it, its pipe is gone up has nozzle over against the burner hearth place, and nozzle has one at least, water inlet pipe is equipped with in the outer wall bottom, opposite of outer wall superheated steam bend pipe, and tap and water tank are arranged on the water inlet pipe; Have an air inlet on the outer wall of upper furnace at least, have at least one to arrange, whenever drain into rare three air admission holes on the inwall; The fire grate plate is that comb, periphery are the monoblock type of plate in the middle of being, air inlet is arranged on its plate; The shape of cross section of burner hearth is circular, or square, or rectangle; The body of heater cross-sectional outer is a square, or circular, or rectangle.

After employing has the energy-conservation stove that produces combustion-supporting gaseous mixture device, owing to rise to more than 500 ℃ in fire box temperature, the tap of fetching boiling water, water passes the loose metal composites in the lower hearth enclosed cavity, the gaseous mixtures such as hydrogen of overheated steam and production have been formed, spraying to lower hearth by the nozzle on the superheated steam bend pipe just burns with help in burnt fuel, in combustion process, generate gaseous mixtures such as carbon monoxide and hydrogen again rapidly, these gaseous mixtures continue to rise to upper furnace, proceed burning with the air that enters by pore, thereby make fuel be able to abundant burning.After measured, use this energy-conservation stove and compare with the energy-conservation stove of common usefulness, not only can economize on coal reaches more than 50%, improves the thermal efficiency more than 75%, and smoke dust discharge concentration: lingemann blackness is less than one-level, and concentration is less than 150mg/Nm ³

Accompanying drawing below in conjunction with specific embodiment is described in further detail the utility model.

Accompanying drawing is the cutaway view of the stereogram of a specific embodiment of the present utility model.There is shown, the cross section of energy-conservation stove outer covering 1 is a square, and chimney 2 is equipped with on rear wall top, stove plate 3 is arranged at its top, and the antetheca below has fire door 15, and the whole body of heater of four footing, 14 supportings is arranged at the bottom, center fixed has fire grate plate 17, and the space of the housing 1 of fire grate plate below 17 is grey chamber 16; Be circular the comb in the middle of the fire grate plate 17, be square plate outward, and three air inlets 13 are arranged on the plate; Upper and lower burner hearth 7,10 places on the fire grate plate 17, and its burner hearth cross section is circular, and the last plane periphery of upper furnace 7 is a square, and uniform four air inlets 9 have three rows on its outer wall 23 on the inwall 22, uniform 12 air admission holes 8 of every row; The inside and outside wall 20 of lower hearth 10, the cross section of 21 formation is that the banded iron of car, drilling machine processing being housed quiet in the enclosed cavity 11 of rectangle is main metal composites 12, on the top of outer wall 20 superheated steam bend pipe 19 is housed, uniform five nozzles 18 on it, between the fire bars gap of the spray orifice aligning fire grate plate 17 of nozzle 18 and over against burner hearth, water inlet pipe 4 is equipped with in bottom over against bend pipe 19 installation place outer walls 20, is equipped with tap 5 on the water inlet pipe 4, end is equipped with water tank 6.Water tank 6, tap 5, water inlet pipe 4, enclosed cavity 11, metal composites 12, superheated steam bend pipe 19 and 18 at nozzle have been formed an intact device that produces combustion-supporting gaseous mixture.
