Abstract

The utility model relates to a back-firing atmospheric furnace, which is a new style furnace for heating. The structure of the furnace is composed of a burning chamber, a furnace dust chamber and a water system. The utility model is characterized in that the gasifying dry distillation rule is fully utilized when coal is burnt, which cause the coal to be sufficiently burnt. Simultaneously, the flame is downward to pass through a fire grate to form the back-firing, the utility model not only heats the water in the water service pipe of the fire grate, but also eliminates smoke and dust. The utility model has the advantages of simple structure, good coal-saving effect, high thermal efficiency, no environment pollution. In addition, the heat efficiency can reach to more than 88%, and the utility model can be used in any environment for heating. Thus, the utility model is a new style back-firing atmospheric furnace with highly efficiency, energy saving and pollution prevention.

Description

The anti-atmospheric pressure kiln that burns

Anti-burning atmospheric pressure kiln described in the utility model is a kind of heating equipment that can be used for central heating such as hotel, restaurant, office, school, private residence, also can be used for bathing pool.

Present normal-pressure boiler has various ways, though through repeatedly improvement, but still be stuck with old pattern.Its shortcoming be coal directly put into combustion chambers burn, coal dust and fuel gas also be not able to do in time the burning just discharge with flue.Add the upper furnace door heat radiation, wasted a large amount of energy, the thermal efficiency is low, the energy-saving dedusting smoke effect is poor.At existing problem in the prior art, a kind of novel boiler of research and design, existing problem is very necessary in the prior art thereby overcome.

In view of existing problem in the above-mentioned prior art, the purpose of this utility model be a kind of coal of can following of Development and design in the gasification destructive distillation rule in when burning, coal is fully burnt.Make flame form anti-burning, not only make as the water in the water service pipe of fire grate and be heated through fire grate simultaneously downwards, but also reach the purpose of smoke abatement and dust control.The utility model is simple in structure, effect of coal saving good, the thermal efficiency is high, free from environmental pollution, the thermal efficiency can reach more than 88%, can be used for any heating environment, is that a kind of efficient, energy-conservation, antipollution novel trans is burnt atmospheric pressure kiln.

The utility model is a kind of anti-burning atmospheric pressure kiln, and its structure is made up of combustion chamber, ashes chamber, water system.The position, combustion chamber is that heat exchanger smoke pipe and flue, water system are made up of housing in right side, the ashes chamber of integral body at bottom, the upper left quarter of integral body.Combustion chamber described in the utility model is made up of coal filling hole, refractory lining, fire grate, heat exchanger smoke pipe; The ashes chamber is made up of dedusting pond, cleaning door, flue; Water system is made up of water inlet, delivery port, water jacket, water service pipe.Fire grate described in the utility model be by round steel bar last by water pipe under be mutually 90 ° of welded corner joints and form.Water service pipe described in the utility model communicates with water jacket, flows in the water jacket by the water after the water pipe heating and goes.

The utility model provides a kind of novel anti-burning atmospheric pressure kiln, thereby the disadvantage of wasting energy of having overcome that existing boiler exists, contaminated environment has been released a kind of simple in structure, efficient low-consume, anti-burning atmospheric pressure kiln that smoke medicining dust-removing effect is good, widely applicable to market.The utlity model has novel structure, economize on coal, not over-emitting black exhaust, do not have dust, free from environmental pollution, the thermal efficiency can reach 88% with first-class advantage.It puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.

The utility model accompanying drawing is the anti-normal-pressure boiler schematic diagram that burns

Among the figure: 1. dedusting pond 2. cleaning doors 3. heat exchanger smoke pipes 4. water jackets 5. cleaning doors

6. flue 7. delivery ports 8. refractory linings 9. round steel bars 10. coal filling holes

11. water service pipe 12. cleaning doors 13. water inlets

Specific embodiment of the utility model as shown in drawings, its structure be combustion chamber and water jacket to be heated, heat exchanger smoke pipe, flue not on straight line up and down, but become left and right sides structure.Flame in the combustion chamber arrives the heat exchanger smoke pipe downwards from fire grate, discharges from flue at last, has walked a U font, forms instead and burns.Initiate coal is added in spent coal top in the combustion chamber, makes initiate coal through the gasification retort process.This process is to be heated to when taking the photograph the third constellations 100 and spending when coal, and coal is in drying stage; Element and gas when the taking the photograph the third constellations 200 and spend of coal heating, in the coal are separated out; When being heated to when taking the photograph the third constellations 350 and spending, coal begins to soften, bond; When being heated to when taking the photograph the third constellations 550 and spending, coal begins again to solidify, and makes the coal line of softening bonding be cleaved into fritter, become semicoke and coke.Coal gasification retort process that Here it is.The most prosperous through the coal combustion after this process, firepower is the strongest.When burned flame process fire grate,, heated by the heat exchanger smoke pipe again the heating of the water in the water service pipe, heated current direction water jacket.Heated water is supplied with the user from delivery port, and the coal ash of burned mistake arrives the dedusting pond through fire grate downwards, discharges from cleaning door.
