Description
Technical field
The present invention relates to a kind of combustion energy saving control system, specifically a kind of New-type boiler control device.
Background technology
Coal is the main energy sources of China, and the 84% of coal in China is used to directly burn, due to coal combustion equipment and burning skill
Art falls behind relatively, thus brings that efficiency of combustion is not high and the serious two large problems of environmental pollution.By taking Industrial Boiler as an example, China is existing
There is coal-burned industrial boiler more than 520,000, annual consumption coal accounts for the 35% of coal production total amount, but average boiler efficiency only has
60%, lower than the efficiency of advanced country 80% more than 20 percentage points, only this item is annual to waste nearly 100,000,000 tons of raw coal, main original
Because being：1）Most Industrial Boilers are chain furnace.Design thermal efficiency itself is relatively low.The combustion process of grate furnace is to coal and particle
Degree has certain requirement, and under conditions of China is current, the often supply of coal can not meet design coal characteristic and granularity
Requirement；2）China supplies the marketable coal of Industrial Boiler, is the raw coal without washing, therefore from the supply angle of coal,
The requirement of chain furnace efficient burning can not be met；3）Management and operation level are low；4）Strict implement environmental law is unable to industrial pot
The requirement that fire grate is put, while lack and promoting to improve Industrial Boiler efficiency and reducing " driving force " of pollutant emission.China is big absolutely
Part atmosphere pollution is caused by coal combustion.Therefore, efficiency is improved, pollution is reduced, is China's Future Development coal combustion technology
Primary guiding principle.Because miniature boiler efficiency of combustion is low, disposal of pollutants is more serious, has moved towards to be removed by enterprise gradually, quilt
The edge of market.But, we also, it is understood that country advocate dismounting miniature boiler there is also in itself it is many helpless because finish
Unexpectedly these boilers are not yet reached and scrap the time limit, and assets certainly will be caused to waste after dismounting；In addition, newly-built large-sized boiler, is also in itself
It is also kind of a covert destruction to environment in consumption metal and mineral resources.Therefore, how under the conditions of existing, lifted small-sized
Boiler combustion efficiency, reduces pollutant emission, is only what country really advocated.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, it is proposed that a kind of New-type boiler control device, the control system solution
Determined how to make under existence conditions boiler combustion efficiency maximum problem --- automatic burning optimisation technique can make boiler thermal effect
Rate improves 2~5%, and substantially reduces flying dust amount and unburned carbon in flue dust, and the thermal efficiency at limited scene can be higher than 5%.
The technical scheme is that：A kind of New-type boiler control device, including combustion control system, boiler and
Fuel improves add-on system, is connected by a boiler interface module between the combustion control system and boiler, fires
Material improvement add-on system is connected by holding wire with combustion control system, and the fuel improvement add-on system is by conveying
Line is connected with boiler, and control system, data collecting system and air preheater are provided with the boiler.
The combustion control system is connected with boiler interface module by holding wire.
The boiler interface module is connected with boiler by holding wire.
The present invention has the advantages that：
1）The present invention solves the problems, such as how to make boiler combustion efficiency maximum under existence conditions --- automatic burning optimizes skill
Art can make boiler thermal output improve 2~5%, and substantially reduce flying dust amount and unburned carbon in flue dust, and the thermal efficiency at limited scene can be high
In 5%.
2）The present invention solves pollution problem of the boiler to environment to a certain extent --- and it had both met filling for fuel
Divided combustion, also ensure that the stabilization burning of boiler, efficiently solve chimney over-emitting black exhaust and S02, NOx because ignition temperature is controlled not
The steady and excessive environmental issue for generating.
3）This invention greatly reduces the labour intensity of workman --- it has broken boiler and has been substantially at people for a long time
The situation of work operation, production efficiency is significantly improved.
4）It significantly extends the overhaul life of boiler --- and system makes boiler for producing run more steady and more pacify
Entirely.
5）Than being significantly improved before transformation after thermal efficiency transformation, when the thermal efficiency is below 65% before transformation, generally improve
10% or more than 10%.Coal saving rate is 10%~30%.
6）Discharge is reduced, and dust, slag, S02 discharges are greatly lowered, and have purified surrounding enviroment.
7）The discharge of flue gas heat is greatly reduced, pollution is reduced.
8）Drum, air inducing, crush, the machine power reduction such as conveying, economize on electricity 10% --- and 30%.Extend the use longevity of air-introduced machine
Life.
