Referring to FIG. 1, Fig. 1 is to be contained in the embodiment of the present invention based on the reduction flying dust monitored on-line of water cooling wall region CO in furnace
The method of carbon amounts is applied to the structure schematic diagram on the Process In A Tangential Firing of thermal power plant.
Thermal power plant Process In A Tangential Firing includes furnace body 1, and burner 2 is provided in the burning zone of furnace body 1, is passed through
Pulverizer coal feeder or coal pulverizer and primary air system, secondary air system realize the operation of burner 2.
By the conveying capacity of pulverizer coal feeder or coal mill control coal dust, first and second wind system by setting First air air door and
Secondary Air air door realizes that the air output of primary air-supply and secondary blast is adjusted.For burner 2 operation control, be by to
What the control of powder machine or coal pulverizer, First air air door and Secondary Air air door was realized.
To known to the analysis of existing heat power plant boiler operation adjusting meaning: the prior art can not be learnt every in Boiler Furnace
The combustion intensity of one layer of burner can not precisely adjust each layer of burner, can only carry out integrated regulation, in this way can not
Meet the fining adjustment requirement that each layer of burner keeps good combustion.
The method of the reduction unburned carbon in flue dust provided by the present invention monitored on-line based on water cooling wall region CO in furnace is one
Kind realizes that reducing flying dust contains to Process In A Tangential Firing based on water-cooling wall CO on-line measurement in furnace and the adjustment of related system control
The technology of carbon amounts is the burning optimization design scheme that a kind of pair of thermal power plant Process In A Tangential Firing reduces unburned carbon in flue dust.
In the prior art, firing optimization is to realize control by the oxygen amount in the flue gas after integral combustion, due to
Boiler lacks effective monitoring of the combustion position to each burner, each layer of burner, so the coal dust of every layer of burner
Concentration, air quantity are the extensive adjustment assumed as a matter of course according to perfect condition, exist in the process of running which results in boiler and begin
There is the case where partial combustion burner is unable to full combustion eventually.
In order to solve this problem, the present invention is based on traditional thermal power plant Process In A Tangential Firings, to its combustion monitoring control
System processed has carried out structure optimization, increases burner hearth CO on-line monitoring system and boiler flyash carbon content in-line analyzer.Specifically
Ground, monitoring and control system include that the burner hearth CO on-line computing model 3 being set on furnace body 1 and burner hearth CO on-line computing model 3 are believed
The DCS system 4 of number connection and the operator station being connect with 4 signal of DCS system and engineer station 5.By CO on-line computing model 3,

In the present invention, pulverizer coal feeder or coal pulverizer and primary air system monitor and control system can be to pulverizer coal feeder or coal pulverizer
It is controlled with primary air system and secondary air system, control parameter is each burner 2 CO into fiery side region
Content, therefore, the present invention provides burner hearth CO on-line computing model 3, burner hearth CO on-line computing model 3 is supervised for realizing CO content
It surveys.
Specifically, burner hearth CO on-line computing model 3 is provided with multiple and corresponds with burner 2, is right with it for obtaining
The CO content for 2 peripheral region of burner answered, CO on-line computing model 3 connect with 4 signal of DCS system, the CO for being obtained
Cont signal is sent to DCS system 4, DCS system 4 connect with operator station and 5 signal of engineer station, for operator station and
Engineer station 5 sends signal and receives the control signal sent by operator station and engineer station 5, DCS system 4 and pulverizer coal feeder
Or coal pulverizer and primary air system and secondary air system control connection, for coal dust supply amount and primary air velocity, secondary
Air door is controlled.
In order to improve control precision of the invention, present invention further introduces back-end ductwork CO contents, boiler flyash carbon content
As control parameter.In the present embodiment, monitoring and control system further include having for online to boiler back end ductwork progress CO
The monitor 6 and unburned carbon in flue dust in-line analyzer 7 of monitoring.Unburned carbon in flue dust in-line analyzer 7 and back-end ductwork CO exist
Line monitor 6 is connect with 4 signal of DCS system.
Based on said structure design, the present invention passes through the monitoring to each CO in flue gas near fiery side of burner 2, root
According to the corresponding relationship of CO in flue gas and combustion intensity, the combustion intensity of each burner is monitored and is adjusted, is made each
The combustion efficiency of burner 2 can keep good state, reduce boiler flyash carbon content, improve the economy of boiler.
The present invention has creatively used CO monitoring technology in furnace, can be generated to each burner 2 to burn in furnace by burning
The content of CO carries out real-time measurement in flue gas, according to the corresponding relationship of CO content and combustion intensity near water-cooling wall 7 in furnace, passes through
The variation judgement of CO data is come out of the stove interior the case where burning everywhere, further according to coal powder density, the primary air velocity wind for needing adjustment region
Amount, secondary air register achieve the effect that improve efficiency of combustion, reduce unburned carbon in flue dust to change the CO content in the region, thus
Improve the economy of boiler.The present invention can in real-time monitoring furnace multiple spot combustion intensity, and carried out according to continuous measurement result
Adjustment is all burnt good effect to reach each burner 2 in Boiler Furnace, reduces boiler flyash carbon content, improves pot
Furnace economy.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
