Abstract
The invention relates to a boiler for a coal electric shaft power station. The boiler is characterized in that the upper part of a combustion chamber is provided with a boiler drum in which fresh water and an electric heater are arranged, and the electric heater is immersed by the fresh water; the periphery of the combustion chamber or the outer wall is provided with a boiler combustion chamber; a heating furnace tube is arranged in the combustion chamber and connected with the fresh water in the boiler drum; the lower part of the combustion chamber is provided with a slag and dust discharge opening and a horizontal fume discharge outlet. Unsteady electric energy generated by coal electric shaft, consumed wind energy and solar energy is converted into a steady electric energy by using a reasonable control method, in order to provide heat and steam to enterprises and urban residents. The following purpose can be achieved by the boiler: coal dust consumption and environmental pollution are reduced; the wind energy, the solar energy and green electric energy can be consumed in the maximum limit. The unsteady electric energy generated by the wind energy and the solar energy is converted into the steady electric energy.
Description
Technical field
The present invention relates to and a kind ofly can utilize coal dust and electrical energy production steam and be applicable to the boiler of thermal power generation or heat supply steam supply, specifically power station, a kind of coal Electricity Federation boiler.
Background technology
At present, thermal power generation mainly uses fossil fuel as coal dust or production of hydrocarbons steam.Boiler shape mainly contains coal-burning, fuel combustion type and gas type.China is owing to having abundant coal resources, and thermal power generation mainly adopts coal-burning type boiler.But utilize these fossil fuels can produce a large amount of CO
2, N
2o, SO
2and dust, cause the severe contamination of environment.
Along with the enhancing of people's environmental consciousness, the green energy resource such as wind energy, solar energy is rapidly developed in recent years.At present, wind energy, solar electrical energy generation have accounted for certain ratio in total generated energy.But there is very large uncertainty due to wind-force size and sunlight strength, therefore wind energy, solar electrical energy generation are also just thereupon off and on, shortcoming little, very unstable time large when existing.These problems cause great impact to electrical network and electrical equipment.In the better Xinjiang of wind energy resources, the Inner Mongol, Hebei and three provinces in the northeast of China, due to a large amount of unstable wind-power electricity generation and the solar electrical energy generation of cannot dissolving, have to abandon electricity to the wind-powered electricity generation of green or process of rationing the power supply.On the one hand consumption of fossil fuels and polluting, gives it up to green energy resource on the other hand, causes significant wastage.How to dissolve wind energy, solar energy electricity just can become new forms of energy and develop a difficult problem urgently to be resolved hurrily.
In order to address this problem, the invention provides power station, a kind of coal Electricity Federation boiler, wind energy of can all dissolving, sun the subject of knowledge and the object of knowledge generating energy, reduces Fossil fuel consumption, reduces environmental pollution.
Summary of the invention
The present invention, for solving existing problem, aims to provide power station, a kind of coal Electricity Federation boiler.
The technical solution used in the present invention comprises combustion chamber, boiler-steam dome, electric heater, furnace tubing and boiler furnace, wherein, the top of combustion chamber is provided with boiler-steam dome, and described boiler-steam dome is built-in with clear water and electric heater, and described clear water submergence electric heater; Surrounding or the outer wall of combustion chamber are provided with boiler furnace;
Be provided with furnace tubing in combustion chamber, the clear water in furnace tubing and boiler-steam dome is connected; The bottom of combustion chamber is provided with the opening of slag dirt discharge, and the bottom of combustion chamber is also provided with the gas outlet of the discharge flue gas of level.
Wherein, in the gas outlet of the discharge flue gas of described level, also air preheater is provided with.
Wherein, chamber wall adopts inner lining refractory or cold wall construction.
Compared to the prior art, the present invention is by coal Electricity Federation use, and the unstable electric energy that wind energy of dissolving, sun the subject of knowledge and the object of knowledge are produced, utilizes rational control method, it is converted into a kind of stable electric energy, or be enterprise, city dweller's heat supply steam supply.The present invention can arrive following object: 1) reduce coal consumption, reduces environmental pollution; 2) to dissolve to greatest extent the green energy such as wind energy, solar energy.3) unstable electric energy conversion wind energy, solar energy etc. produced is stable electric energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
See accompanying drawing, 1 is boiler-steam dome, and 2 is electric heater, and 3 is coal burner, and 4 is boiler furnace,
5 is drum gas phase zone, and 6 is drum liquid phase region, 7 for furnace tubing be 8 air preheaters.
Detailed description of the invention
Now by reference to the accompanying drawings the present invention is further described.
See Fig. 1, Fig. 1 displaying is one embodiment of the present of invention, comprises combustion chamber, and combustion chamber locular wall adopts inner lining refractory or cold wall construction; Comprise boiler-steam dome 1, electric heater 2, furnace tubing 7 and boiler furnace 4 in addition.Wherein, the top of combustion chamber is provided with boiler-steam dome 1, and described boiler-steam dome 1 is built-in with clear water and electric heater 2, and described clear water submergence electric heater 2.The first half of boiler-steam dome 1 defines drum gas phase zone 5, and the Lower Half of boiler-steam dome 1 defines drum liquid phase region 6.
The surrounding of combustion chamber or outer wall are provided with boiler furnace 4; Outer wall is pressed coal dust firing heating feature and is arranged boiler furnace 4.Boiler furnace 4 regulates flame and caloric value by increasing-reducing inlet valve aperture size.
Be provided with furnace tubing 7 in combustion chamber, the clear water in furnace tubing 7 and boiler-steam dome 1 is connected; Adopting vertical or alternate manner layout furnace tubing 7 in combustion chamber, is clear water in furnace tubing 7, becomes superheated water or steam by absorbing the heat of coal dust firing generation.
The bottom of combustion chamber is provided with the opening of slag dirt discharge, and the bottom of combustion chamber is also provided with the gas outlet of the discharge flue gas of level.In order to make full use of the heat of flue gas, by the air preheater 8 be provided with in the gas outlet of the discharge flue gas of described level, preheating is carried out to the air entering burner.
The present invention can adopt separately coal dust firing to produce steam or utilize separately electrical bar to produce steam, also conbined usage coal dust firing and electric heater 2 can produce steam.During normal work, mainly dissolve wind-powered electricity generation and solar energy, utilize electric heater 2 to produce steam, when the steam that electric heater 2 is produced is not enough, start or strengthen the boiler furnace 4 of combusting coal fines, ensureing the steam turbine vapour in TRT or heat supply, making generator can stable electric generation.And combusting coal fines and the hot water heated can mix with electrically heated hot water, the steam produced all concentrates in boiler-steam dome 1.
Above by reference to the accompanying drawings and embodiment describe embodiments of the present invention; the structure that embodiment provides is not construed as limiting the invention; in this area, those skilled in the art can adjust according to needs, make various distortion within the scope of the appended claims or revise all in protection domain.
