Description
Technical field
The present invention relates to thermal power generation, and in particular to a kind of thermal power plant Combustion Efficiency of Coal Powder monitoring system.
Background technique
The thermal energy that thermal power generation generates when generally referring to using combustible combustion heats water, so that the water is become high temperature, high pressure
Vapor, the mode general name then to be generated electricity again by vapor pushing generator, thermal power generation capital equipment system includes: fuel
Feed system, water supply system, vapour system, cooling system, electrical system and some other auxiliary treating apparatus.It is supplied in fuel
Fuel provided by system is coal, usually requires to be ground into coal dust use, to improve efficiency of combustion, and what coal was ground into
The size of pulverized coal particle is one of an important factor for directly influencing its efficiency of combustion, and the prior art is not yet specifically for coal dust
The effective means that is monitored of efficiency of combustion.
Summary of the invention
The present invention is for the effective means of the existing technology not being monitored to the efficiency of combustion of coal dust specially
Problem provides a kind of thermal power plant Combustion Efficiency of Coal Powder monitoring system, in application, can fire to the coal dust in thermal power plant
It burns efficiency and carries out effective monitoring.
The invention is realized by the following technical scheme:
A kind of thermal power plant Combustion Efficiency of Coal Powder monitoring system, including coal pulverizer, controller, gas detecting instrument and carbon containing
Detection device is measured, is equipped with microprocessor, power module and wireless communication module, power module, wireless communication in the controller
Module, coal pulverizer, gas detecting instrument and phosphorus content detection device are electrically connected with microprocessor, and microprocessor passes through channel radio
Letter module is connect with monitoring backstage signal.
Further, the adjustable pulverized coal grinding fineness of the coal pulverizer.
Further, the carbon monoxide content that the gas detecting instrument generates burning is acquired, while being contained to other
Sulphur, nitrogenous gas are detected.
Further, the coal ash carbon content that the phosphorus content detection device generates burning detects.
It is in application, the coal dust being ground is sent into thermal power plant according to pre-set fineness of grind by coal pulverizer
Combustion system is burnt；The gas that gas detecting instrument generates coal dust firing is acquired, and detects wherein carbon monoxide
Content, and gas detection data are transmitted to microprocessor；The coal ash that phosphorus content detection device generates coal dust firing is adopted
Collection, detects the carbon content in coal ash, and carbon content data are transmitted to micro process；The acquisition data that microprocessor will be collected into
It is handled, and monitoring backstage is sent to by wireless communication module；The data received are analyzed on monitoring backstage, if coal
The coal ash carbon content that carbon monoxide content is higher or coal dust firing generates in the gas that powder burning generates is higher, shows coal
Powder burn in the combustion system in thermal power plant it is insufficient, at this time monitoring backstage to microprocessor send control command, micro- place
The fineness of grind of coal pulverizer is adjusted in reason device, and the pulverized coal particle that it is ground is more tiny, to fill in combustion system
Divided combustion improves the efficiency of combustion of coal dust.
The present invention has the advantage that and the utility model has the advantages that
1, a kind of thermal power plant Combustion Efficiency of Coal Powder monitoring system of the present invention, coal dust firing can be generated it is carbon containing,
The gases such as sulfur-bearing, nitrogenous are detected.
2, a kind of thermal power plant Combustion Efficiency of Coal Powder monitoring system of the present invention, can be to the coal ash that coal dust firing generates
Phosphorus content is detected.
3, a kind of thermal power plant Combustion Efficiency of Coal Powder monitoring system of the present invention, can be to the coal dust firing in thermal power plant
Efficiency carries out effective monitoring.
