Description

Regenerator boiler
Technical field
The invention belongs to boiler plant technical field, specifically a kind of regenerator boiler.
Background technology
Along with the continuous propelling of economic globalization, resources and environment problem day is aobvious outstanding, and boiler and stove are as the rich and influential family of energy resource consumption, and the power-saving technology how carrying out high-efficiency environment friendly as early as possible becomes the most important thing.Boiler is a kind of energy conversion, and the energy to boiler input has the forms such as the heat energy of chemical energy in fuel, electric energy, high-temperature flue gas, and through boiler conversion, outwards exports steam, high-temperature water or the organic heat carrier with certain heat energy.But the discharge of the energy utilization rate of boiler and pollutant is all boiler urgently improves.
Summary of the invention
The present invention, in order to solve the problem of the discharge of energy utilization rate and pollutant, provides a kind of regenerator boiler especially.
The present invention takes following technical scheme: a kind of regenerator boiler, and comprise body of heater, combustion chamber, Heat Room and water tank, body of heater is provided with return pipe, be provided with combustion chamber in body of heater, combustion chamber is connected with Heat Room, also comprises regenerator, Heat Room is connected with regenerator, and regenerator is connected with chimney.
Described combustion chamber comprises normal burning chamber and instead burns room, and normal burning chamber is connected with Heat Room, and anti-room of burning is connected with regenerator by accumulation of heat wind inlet, and regenerator is provided with cold wind import.Be provided with bottom normal burning chamber and just burn fire grate, normal burning chamber side is provided with just burns fire door; Be provided with anti-burn grate bottom anti-burning room, anti-side, room of burning is provided with and instead burns fire door.
Described Heat Room comprises the first subsidiary combustion chamber be connected with combustion chamber, first subsidiary combustion chamber is connected with flue gas communication chamber by the first smoke-box threaded flue, flue gas communication chamber is connected with the second subsidiary combustion chamber by the second smoke-box threaded flue, and the second subsidiary combustion chamber is communicated with regenerator.
Some heat-storing spheres are placed with in described regenerator.
The present invention is made up of two large divisions, and Part I is combustion chamber; Part II is regenerator, body of heater is provided with multiple fuel inlet (just burning fire door and counter burn fire door) and high temperature combustion air inlet (i.e. accumulation of heat wind inlet), high temperature combustion air inlet and regenerator UNICOM, regenerator is connected with cold wind import, normal temperature air carries out waste heat recovery through regenerator, reduces heat-energy losses, improves efficiency of combustion, normal temperature combustion air participates in combustion-supporting after regenerator preheating on the other hand, can improve ignition temperature.
Compared with prior art, Regenerative Combustion Technology of the present invention fundamentally improves the energy utilization rate of boiler and stove, particularly to the Appropriate application of low calorie fuels, the discharge both having decreased pollutant again saves the energy, becomes the advanced technology meeting Current resource and environmental requirement.The employing of regenerative combustion technology enhances again the furnace atmosphere circulation in heating furnace in addition, and the temperature field of even stove, improves the thermal efficiency, and energy-saving effect is highly significant also.

Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of regenerator boiler, comprise body of heater 9, combustion chamber 4, Heat Room 26 and water tank 12, water tank 12 is provided with water-level gauge 11, and body of heater 9 is provided with return pipe 5, is provided with combustion chamber 4 in body of heater 9, combustion chamber 4 is connected with Heat Room 26, also comprise regenerator 21, Heat Room 26 is connected with regenerator 21, and regenerator 21 is connected with chimney 19.
Described combustion chamber 4 comprises normal burning chamber 3 and anti-burning room 8, and normal burning chamber 3 is connected with Heat Room 26, and anti-room 8 of burning is connected with regenerator 21 by accumulation of heat wind inlet 10, and regenerator 21 is provided with cold wind import 22, is regulated by adjusting valve 23.
Described Heat Room 26 comprises the first subsidiary combustion chamber 29 be connected with combustion chamber 4, first subsidiary combustion chamber 29 is connected with flue gas communication chamber 13 by the first smoke-box threaded flue 14, flue gas communication chamber 13 is connected with the second subsidiary combustion chamber 28 by the second smoke-box threaded flue 16, and the second subsidiary combustion chamber 28 is communicated with regenerator 21.Inspection socket 15 is provided with, for checking Heat Room 26 inner case on the upside of Heat Room 26.
Some heat-storing spheres 27 are placed with in described regenerator 21.
The present invention is realized by following two steps:
First flue gas and accumulation of heat flow process: fuel after instead burning fire door 7 and adding in the effect of air blast and air-introduced machine 25, burnt by normal burning chamber 3, first the flue gas produced after burning enters the first subsidiary combustion chamber 29, heat release in the first threaded flue 14 is entered again from the first subsidiary combustion chamber 29, then heat release in the second smoke-box threaded flue 16 is entered through flue gas communication chamber 13, enter in the 3rd threaded flue by the second subsidiary combustion chamber 28, enter in regenerator 21 after heat release, after heat-storing sphere 27 fully heat absorption, enter chimney 19 through exhanst gas outlet 24.The environmental protection and energy saving of whole process smokeless and dust free.
The flow process of the second air and regenerator: cold air enters in regenerator 21 under the effect of air blast, hot-air enters after air preheat to uniform temperature in anti-burning room 8 by accumulation of heat wind inlet 10 by heat-storing sphere 27, carry out disperse mixed combustion, substantially increase the burning velocity of burner hearth, ignition temperature, combustion rate, heat recovery rate reaches more than 80%.
The present invention is applicable to the firing equipment such as boiler, stove, and fuel can be coal, biomass fuel.Boiler and stove use capable of saving fuel about 40%, thus the thermal efficiency of stove is improved greatly, because air preheating temperature improves so flame temperature is also in corresponding improve, Fire Radiation ability strengthens, and firing rate is fast, because the exhausted air quantity of above reason stove reduces, environmental protection, energy-conservation.
