Description
Technical field
The utility model relates to a kind of power plant gas information feed back blower fan, belongs to power plant equipment field.
Background technology
Thermal power plant utilizes coal, oil, natural gas as the factory of fuel production electric energy, its basic process of production is: fuel in the boiler combustion heating water makes into steam, the converts chemical energy of fuel is become heat energy, steam pressure pushing turbine rotates, thermal power transfer becomes mechanical energy, then steam turbine drive electrical generators rotates, and mechanical energy is become electric energy.
Fire coal, is transported to coal bunker from coal yard with coal conveyer belt.Large thermal power plant is all combusting coal fines for improving efficiency of fire coal.Therefore, the raw coal in coal bunker first will be delivered in coal pulverizer and wear into coal dust.The coal dust ground is carried the burner hearth combustion sending into boiler through Powder discharging fan by hot-air.The heat smoke formed after coal dust firing, along the horizontal flue of boiler and back-end ductwork flowing, is released heat, is finally entered deduster, separated by the coal ash after burning.Clean flue gas enters air by chimney under the effect of air-introduced machine.Combustion-supporting air is installed in the air preheater on back-end ductwork by pressure fan feeding, utilizes heat smoke to add hot-air.Like this, make on the one hand the air themperature entering boiler improve, be easy to, outside the catching fire and burn of coal dust, also can reduce exhaust gas temperature on the other hand, the utilization rate of raising heat energy.The hot-air of discharging from air preheater is divided into two strands: one removes coal pulverizer drying and pulverized coal conveying, and it is combustion-supporting that another stock directly sends into burner hearth.The lime-ash of coal-fired after-flame falls in the slag bucket below burner hearth, and reinstates water from deduster isolated thin grey and rushes in mortar pump house, then delivers to grey field by slurry pump.
Economizer is sent into by high-pressure heater at the water in deaerator storage tank in thermal power plant after feed pump boosting.In economizer, water is subject to the heating of heat smoke, then enters in the drum at boiler top.Be thick with water pipe in boiler furnace surrounding, be called water-cooling wall.The two ends up and down of water-cooling wall water pipe are all communicated with drum by header, the water in drum constantly circulates via water-cooling wall, absorb coal by liberated heat in combustion process.Part water in cold wall by ebuillition of heated after be vaporized into water vapour, these saturated vapors by drum top flow out enter in superheater.Saturated vapor continues heat absorption in the superheater, becomes superheated steam.Superheated steam has very high pressure and temperature, therefore has very large calorific potential energy.The superheated steam with calorific potential energy is introduced after steam turbine through pipeline, just calorific potential can be transformed into kinetic energy.Swiftly flowing Steam Actuation turbine rotor rotates, and forms mechanical energy.
Although current existing Fan of Power Plant equipment can meet its user demand, but the carbon monoxide that can not discharge according to fire coal in power plant and the density of sulfur dioxide toxic gas control the operating rate of blower fan, cause toxic gas in power plant to gather too much, harm people's is healthy.
Utility model content
Although the utility model can meet its user demand for current existing Fan of Power Plant equipment, but the carbon monoxide that can not discharge according to fire coal in power plant and the density of sulfur dioxide toxic gas adjust the operating rate of blower fan, toxic gas in power plant is caused to gather too much, the healthy problem of harm people, devises a kind of power plant gas information feed back blower fan.
The technical scheme in the invention for solving the technical problem is:
