Technical field
The present invention relates to Circulating Fluidized Bed Boiler Equipments, more particularly to a kind of oil-free for circulating fluidized bed combustion coal boiler
Ignition system and method.
Background technology
Currently, China's circulating fluidized bed combustion coal boiler mainly uses light diesel fuel as igniter fuel, of high cost, operation difficulty
Greatly.By taking evaporation capacity is the unit of 440 ton hours as an example, furnace igniting is opened every time and continues 6-8 hours, consume No. 0 24-32 tons of diesel oil,
Expend 200,000 yuan or more.Meanwhile it is high to Boiler pressure control requirement using diesel ignition, the excessive boiler that be easy to cause of primary air flow goes out
Fire, and air quantity is too small can cause coking.Therefore, it finds a kind of with cheap, cleaning, the gaseous fuel alternative point kerosene of high heating value
Method, realize coal-burning boiler non-oil ignition seem necessary.
Organic matter (based on volatile matter) in coal will produce largely after circulating fluidized bed boiler emulsion zone is thermally decomposed
Imflammable gas, the mixed gas that it is made of compounds such as various hydrocarbons, hydrogen, carbon monoxide, calorific value are about
16-18MJ/m3, have the characteristics that combustible component is high, impurity is low, utility value is high.Studies have shown that the imflammable gas have with
The similar physicochemical characteristic of coke-stove gas, therefore cannot be only used for preparing natural gas, additionally it is possible to directly it is compressed into row transport and profit
With.In addition, the raw material for preparing imflammable gas is coal, have a clear superiority in use cost compared to diesel oil.It is even more important
, gaseous fuel need not be atomized in igniting, be easier to manipulate compared to liquid fuel.
In summary, above-mentioned imflammable gas is extracted before blowing out, purified device is miscellaneous except the influences such as tar removing compression
It is compressed and is stored in high pressure tank again after matter, as ignition of the boiler fuel, clean environment firendly meets national low-carbon economy
Development strategy.

Demonstrate,prove imflammable gas safety ignition.Air accumulator farther out, avoids influencing each other, ensures site safety with boiler distance.System compatible
Property is good, and set of system can be applied to more boilers at times.
The imflammable gas that volatile matter generates after being thermally decomposed in the fire coal of circulating fluidized bed boiler is drawn into purifier,
It is compressed into 5~20MPa after cooling decontamination and is stored in high pressure tank.When opening stove, imflammable gas diesel oil substitute
Igniter is transported to as the fuel needed for ignition of the boiler.Imflammable gas calorific value is about 16~18MJ/m3, meet boiler
The primary condition of igniting.Imflammable gas needs the when of declining to extract in blowing out moment night the last week boiler load.Gas extraction
Process does not require boiler using coal, but recommends the higher lignite of volatile matter content.Imflammable gas is whole when opening stove
It is sent into burner hearth, reduces or remits the daily explosion-proof work of high pressure tank.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) structure and operation characteristic based on circulating fluidized bed boiler enter the receipts of the imflammable gas of stove release for coal
Collection, purification, compression, storage and its system that the non-oil ignition of boiler is realized using imflammable gas as fuel back into stove, proposition
And method.
(2) the imflammable gas impurity of preparation is few, utility value is high, other than as igniter fuel, can be also used for giving birth to
Producing natural gas；Clean environment firendly, energy-saving and emission-reduction；
(3) substituting liquid igniter fuel with gas igniter fuel securely and reliably reduces and is wanted to the technology of operating personnel
It asks；
(4) apparatus structure is compact, connection and reasonable arrangement, has good expansibility, such as can be used for the daily peak regulation of boiler, carries
High boiler needs the when of reducing to extract imflammable gas the response speed of load in load, it is to be sent into need to improve in load
Imflammable gas；
(5) system is relatively independent, and the operation conditions of boiler influences it smaller.Conversely, system rate of air sucked in required is small, to boiler
Operation conditions influence also very little.
