Description
Technical field
The utility model relates to technical field of power generation, particularly relates to a kind of boiler for heat power station.
Background technology
Thermal power generation, is utilized the heat energy produced when solid, liquid, the gas fuel combustions such as coal, oil, natural gas, is converted to a kind of generation mode of electric energy by generation power device.The rich coal resources of China, nineteen ninety producing coal 10.9 hundred million tons, wherein coal for power generation only accounts for 12%.Thermal power generation still has great potential.Fuel chemical energy → steam thermal energy → mechanical energy → electric energy, be exactly briefly utilize fuel to generate heat, heating water, forms high-temperature high-pressure overheat steam, promotion gas-turbine rotates, drive electrical generators rotor (electromagnetic field) rotates, and stator coil cutting magnetic line, sends electric energy, recycling step-up transformer, be raised to system voltage, with system grid connection, outside transmission of electric energy.
Then steam enters continuous expansion work in steam turbine along pipeline, impacts turbine rotor High Rotation Speed, and steam turbine drive electrical generators generates electricity.Finally boosted further to send back in boiler by feed pump again and repeat to participate in above-mentioned cyclic process, the electricity that generator sends inputs electrical network after transformer boost.
Current boiler is generally at combustion chamber internal-combustion coal, but the contact area of the coal burnt and air is little, cause burning velocity slow, and it is insufficient to burn, and combustion chamber is general only at bottom-heated, causes the water firing rate in boiler slow.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of boiler for heat power station.
The utility model is achieved through the following technical solutions:
A kind of boiler for heat power station, comprise boiler shell, smoke exhaust pipe is provided with on the upside of described boiler shell, side, described boiler shell upper end is provided with water inlet pipe, steam pipeline, side, lower end is provided with outlet pipe, described boiler shell center is provided with combustion chamber, heating water cavity is provided with between described combustion chamber and boiler shell, described bottom of combustion chamber is provided with stuff-spraying pipe, described stuff-spraying pipe is connected with combustion-supporting pump, described stuff-spraying pipe place is provided with igniter, is provided with cinder catcher bottom described boiler shell, is provided with supporting network between described cinder catcher and combustion chamber.
