Abstract
The invention discloses a secondary air combustion-supporting boiler. The secondary air combustion-supporting boiler is formed by a water tank and a boiler body, wherein the water tank is fixedly arranged at the upper end of the boiler body; fuel gas or liquid fuel can be sprayed through a spray nozzle, a flame can be generated after the combustion of the fuel gas and enters a flame zone, high-temperature flue gas enters a six-ridge ceramic pipe through a flue gas inlet passage, air enters a preheat exchange chamber through the bottom part of a preheater, heat can be transmitted from the flue gas to the air in the preheat exchange chamber through the six-ridge ceramic pipe, the air flows upwards and is in staggered contact with the six-ridge ceramic pipe, the temperature of the air rises gradually, the air can be exhausted through an exhaust passage, the fuel can be completely combusted after being in contact with the air, and the flue gas can be exhausted through the six-ridge ceramic pipe. According to the secondary air combustion-supporting boiler disclosed by the invention, combustion air can reach high temperature by utilizing the heat of the flue gas after the combustion, the fuel is completely combusted due to the high-temperature air, the energy source is saved, the fuel consumption is reduced, the working efficiency of the secondary air combustion-supporting boiler is increased, the cost of raw materials is reduced, the pollution to the air after the fuel is combusted is reduced, and the living environment of people is improved.
Description
Technical field
The present invention relates to boiler energy-saving field of Environment Protection, particularly a kind of secondary air combustion aid boiler.
Background technology
Boiler is that we live and equipment indispensable in industrial development, boiler is by stove fuel combustion, transform out desired kinetic energy in people's life and industry, electric energy and heat energy etc., existing boiler, directly after-combustion is contacted with extraneous air by fuel, then heated body is heated, in combustion process, fuel combustion is insufficient, energy resource consumption is large, after burning, heat energy is directly got rid of, cause the waste of heat energy, and high fume temperature, power consumption is large, functional reliability and less economical, boiler preheating is slow, inefficiency, cost of material is high, great destruction is caused to ecological environment, life and the health of people are had a strong impact on.
Summary of the invention
The object of the invention is will solve above-mentioned existing boiler in combustion, fuel directly contacts after-combustion with extraneous air, fuel combustion is insufficient, energy resource consumption is large, functional reliability and less economical, and boiler preheating is slow, inefficiency, great destruction is caused to ecological environment, has had a strong impact on the life of people and the problem such as healthy, and a kind of secondary air combustion aid boiler is provided.
The present invention is made up of water tank and boiler furnace, and water tank is fixedly installed on boiler furnace upper end;
Boiler furnace comprises combustion chamber, flame tunnel, exhausting duct, preheater, ejecting device, smokejack, flame zone and flue, ejecting device is fixedly installed on below combustion chamber, flame zone is arranged on above combustion chamber, preheater is arranged between combustion chamber and furnace body outer wall, exhausting duct is arranged on preheater upper end, flue is equipped with in preheater upper end, and smokejack is arranged on preheater lower end;
Have six rib earthenwares and pre-heat-exchanging chamber in preheater, six rib earthenwares are meander-like, and are arranged in pre-heat-exchanging chamber.
Operation principle of the present invention and process:
Combustion gas or liquid fuel are sprayed by ejecting device, and after burning, produce flame and enter flame zone by combustion chamber, high-temperature flue gas enters in six rib earthenwares by flue, air enters in pre-heat-exchanging chamber bottom preheater, air contacts six rib earthenwares in pre-heat-exchanging chamber, flue gas passes through six rib earthenwares to the air transfers heat in pre-heat-exchanging chamber, air flows upwards and six rib earthenware interlacing contact, air is made fully to absorb heat, air themperature improves gradually, air is discharged by exhausting duct, now air themperature can reach 600 °-900 °, enter combustion chamber, after chamber fuel touches hot-air, full combustion of fuel, air themperature often promotes 100 °, in burner hearth, temperature can improve about 10%, fuel can save about 15%, the intensity of gasification is more than 95%, reduce SO2 emissions about 10%, flue gas is discharged by six rib earthenwares, enter smokejack, and discharged by chimney.
Beneficial effect of the present invention:
Flue gas heat after the present invention utilizes burning makes combustion air reach a high temperature, high temperature air makes full combustion of fuel, economize energy, reduces fuel consumption, burning after heat can directly utilize, save electric energy, functional reliability and economy high, boiler preheating is fast, improve boiler operating efficiency, reduce cost of material, the pollution to air after minimizing fuel combustion, improves the living environment of people.
