The utility model discloses a kind of secondary air combustion aid boiler, be made up of water tank and boiler furnace, water tank is fixedly installed on boiler furnace upper end; Combustion gas or liquid fuel are sprayed by ejecting device, 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, 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 themperature improves gradually, air is discharged by exhausting duct, fuel joint contacts Thorough combustion after hot-air, and flue gas is discharged by six rib earthenwares.Flue gas heat after the utility model utilizes burning makes combustion air reach a high temperature, and high temperature air makes full combustion of fuel, economize energy, reduce fuel consumption, improve boiler operating efficiency, reduce cost of material, pollution to air after minimizing fuel combustion, improves the living environment of people.
Description
Technical field
The utility model 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 purpose of this utility model 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 utility model 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 utility model 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.
The beneficial effects of the utility model:
Flue gas heat after the utility model 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.
