Background technology
Boiler during production of corn starch is typically chosen coal and is generally divided into three phases as fuel, burning of coal process, and first stage is the stage before coal catches fire, and is dried including to coal, makes the moisture in coal evaporate；Second stage is to coal carbonization, separates out volatile matter and forms coke, volatile matter and the burning of coke；Three phases is to make residual coke after-flame in slag ashes.Coal heats in stove, is dried, transpiring moisture, along with temperature increases, in coal, organic matter starts thermal decomposition, from coal macromolecule, mainly rupture the side chain got off and volatile matter that functional group is formed, volatile matter is mainly composed of CO, CO2, H2, H2O, CH4 and various hydrocarbon compound, also includes sulfur-bearing, nitrogen-containing compound etc..Pyrolysis resultant product is the coke (fixed carbon) of polycyclic aromatic core polycondensation, this process coal heat to be absorbed, and when temperature reaches the burning-point of coal, initial burning, the most flammable volatile matter and coke start burning.
Generally, the volatile matter of coal is the highest, and burning velocity is the fastest.And coke is in the whole combustion process of burning, the percetage by weight of carbon is main and kind along with coal is different and different, and the burning time of carbon accounts for the 90% of whole burning time.The combustion process of carbon is mainly the chemical reaction process of carbon and oxygen.Generate CO and CO2Two kinds of gases number, depend primarily on temperature, when about 1200 DEG C, two kinds of percentage compositions are equal, when the temperature increases CO amount increase.Chemical molecular formula C+O2=co2
2C+o2=2co, generally, combustion coal fired boiler is that fuel is added on grate burning, and this burning first-selection is over-emitting black exhaust, forms dust and produce harmful gas, forms coke afterwards and burns, black smoke, dust and harmful gas carry out flue gas excretion by the smoke discharging pipe of burning coal burning boiler, but the smoke discharging pipe of boiler loss heat, conventional smoke discharging pipe cannot utilize this partial heat, have impact on boiler combustion efficiency, and pollute environment, waste fuel.
