Abstract
The utility model discloses an energy-saving smoke eliminating coal-fired reflecting furnace which comprises a furnace body and a furnace hearth arranged in the furnace body. A dreg dropping chamber and an air inlet door are arranged at the lower part of the furnace hearth. The characteristics of the reflecting furnace are as follows: a charging supporting plate is arranged at a charging opening of the furnace hearth, a coal pushing device is arranged at the position of the charging supporting plate, a coal bucket is arranged above the charging supporting plate, a downwards-inclined slope grate and a horizontal flat grate are sequentially connected from the front end of the charging supporting plate in the furnace hearth, an inward parabolic arch is arranged at the top part of the furnace hearth, an inwards-inclined rear arch is arranged above the parabolic arch, and a smoke discharging channel is formed between the parabolic arch and the rear arch. The energy-saving smoke eliminating coal-fired reflecting furnace effectively solves the problem of black smoke after a fire is lit on the furnace, adopts the coal bucket and the coal pushing device to carry out combined charging, realizes coaling without the opening of a furnace door, avoids the lowering of the furnace temperature due to that cold air enters the furnace hearth, and truly meets the requirements for energy saving, environmental protection and high efficiency.
Description
Technical field
The utility model relates to the coal-fired reverberatory furnace of a kind of energy-saving and smoke-removing.
Background technology
Need increase charcoal in the steel-making product, this charcoal is with the product of extraordinary anthracite after destructive distillation is handled, and the gas retort (being commonly called as general forge) of producing this charcoal burns after the bituminous coal igniting gives birth to stove, and over-emitting black exhaust reaches 70 days, though be that slow fire heats up, be open question for a long time to the pollution of environment.Brickkiln or other brickkilns or other brickkilns baked bricks with clay in vast rural area, igniting were given birth to behind the stove general over-emitting black exhaust 4 to 5 days, also were open questions for a long time.Black smoke is coal-fired subparticle, along with chimney is gone out and wasted the energy greatly; At present great majority all adopt the hand shovel(l)ing of coal mode, can make cold air enter burner hearth and reduce furnace temperature when throwing coal opening, and efficiency of combustion is reduced and waste energy.
The utility model content
The technical problems to be solved in the utility model is to overcome above the deficiencies in the prior art, provides that a kind of furnace temperature height, fire coal are fully burned, not over-emitting black exhaust, energy-conserving and environment-protective, the easy to operate coal-fired reverberatory furnace of energy-saving and smoke-removing.
The technical scheme that realizes the utility model purpose is as follows:
The utility model comprises body of heater, is located at the burner hearth in the body of heater, slag removing chamber and shutter are located at lower furnace portion, the charging supporting plate is located at the burner hearth charging aperture, setting pushes away device for coal at charging supporting plate place, the top of charging supporting plate is provided with coal bunker, in the burner hearth from the front end of charging supporting plate connect successively one under oblique the landslide fire grate and the plain grate of a level, roof of the furnace is inside parabolic arch, the parabolic arch top is provided with intilted rear arch, forms smokejack between parabolic arch and the rear arch.
For best, parabolic arch concentrates on the focal line place with the caloradiance of whole burner hearth to the focal line of described roof of the furnace parabolic arch in fire coal enters the 100mm～200mm scope of burner hearth front end, and the temperature height can impel the fire coal of focal line below fire burns.
Described plain grate afterbody below slag removing chamber is provided with slag trap, and slag is fallen by slag trap, and the slag trap of setting can be controlled slag removing chamber's slag blanket height and air leak rate of air curtain, so more helps energy-conservation.
Adopt the manual or electronic device for coal that pushes away that the fire coal on the coal bunker below charging supporting plate is pushed burner hearth, parabolic arch is concentrated caloradiance in the burner hearth and is made the fire coal of front end fire burns, pushing away device for coal promotes spent coal with new coal and advances, fire coal is fully burned on sloping fire grate of slide and plain grate, slag after burning is disclosed into rear portion slag removing chamber, go out clearly in the lump with sloping fire grate of slide and plain grate whereabouts ash, flame and high-temperature flue gas are walked around rear arch and are gone the heating clamber supply to use after the reflection once more by rear arch in smokejack, in the flue gas with the thin bituminous coal particle of residue by falling in the burner hearth burning once more after the reflection once more, the oxygen (air-supply) that burns required is entered by shutter.
Compared with prior art, the utility model efficiently solves the problem of over-emitting black exhaust behind the living stove and adopts coal bunker combine and feed in raw material with pushing away device for coal, and not blow-on of realization coal door has been avoided cold air to enter burner hearth and reduced furnace temperature, really realized the requirement of energy-saving, environment-friendly and high-efficiency, and easy to operate.
