    燃气锅炉与燃煤锅炉使用有什么不一样?

    1、燃烧方式
    1. Combustion mode
    循环流化床燃煤锅炉是将煤通过破碎真人对赌网址 ,经皮带进煤仓,通过给煤机利用播煤风,撒入炉膛;通过循环灰加热,流态化燃烧过程。而煤改气后将焦炉煤气和驰放气混合合由四个燃烧器喷入直接燃烧。
    Circulating fluidized bed coal-fired boiler is the coal through the crushing equipment, through the belt into the coal bunker, through the coal feeder use of coal sowing air, into the furnace; through circulating ash heating, fluidized combustion process. After changing coal to gas, coke oven gas and purge gas are mixed and injected into four burners for direct combustion.
    2、燃烧产物
    2. Combustion products
    煤主要是由C、H、O、N、S等元素和灰分及水分组成,煤燃烧放出热量后,生成SO2、SO3、NOx灰分和水分,而SO2、SO3、NOx由烟气排入大气,污染环境,对人类造成危害。而天然气的主要成分是CO和H2,经过燃烧后,主要生成CO2和H2O,相对燃煤锅炉燃气锅炉的排放SO2、SO3、NOx要少得多。
    Coal is mainly composed of C, h, O, N, s and other elements, ash and moisture. After coal combustion gives off heat, it generates SO2, SO3, NOx ash and moisture, while SO2, SO3 and NOx are discharged into the atmosphere by flue gas, polluting the environment and causing harm to human beings. The main components of natural gas are CO and H2. After combustion, they mainly generate CO2 and H2O, which are much less than the emission of SO2, SO3 and NOx from coal-fired boiler and gas-fired boiler.

    3、通风方式
    3. Ventilation mode
    燃煤锅炉一般采用负压燃烧,基燃烧过程是由鼓风机和引风机的配合配合的配合来共同完成,煤在燃烧过程中,需要大量的空气,而由于炉墙烟道的漏风,过量空气系数可达2.1-2.5之间。燃气锅炉采用微正压或微负压燃烧,需要的风量小,在燃烧器内空气能较好的与天然气预混。微正压燃烧没有炉墙和烟道的漏风因素,运行中烟道出口空气系数可为1.05-1.2。
    The coal-fired boiler generally adopts negative pressure combustion, and the basic combustion process is completed by the cooperation of blower and induced draft fan. In the combustion process of coal, a large amount of air is required. Due to the air leakage of furnace wall flue, the excess air coefficient can reach 2.1-2.5. The gas-fired boiler adopts micro positive pressure or micro negative pressure combustion, which requires small air volume and can be premixed with natural gas in the burner. Micro positive pressure combustion has no air leakage factor of furnace wall and flue, and the air coefficient of flue outlet can be 1.05-1.2 during operation.
    4、燃料易爆性
    4. Fuel explosibility
    燃煤锅炉燃烧安全,炉膛不易发生爆炸危险。而燃气锅炉在爆炸浓度界限内,遇到明火就会发生爆炸。危险性较大。
    The combustion of coal-fired boiler is safe and the furnace is not easy to explode. However, the gas-fired boiler will explode in case of open fire within the explosion concentration limit. High risk.
    5、锅炉自动控制
    5. Boiler automatic control
    燃煤锅炉由于受到煤种、料层厚度、鼓风量、引风量、风煤配比等原因,要做到根据负荷来自动调节锅炉运行参数的难度大。而燃气锅炉所受影响因素较少,可根据负荷调节燃烧器阀门大小,容易实现自动控制。
    Due to the coal type, material layer thickness, blast volume, induced air volume, air coal ratio and other reasons, it is difficult to automatically adjust the boiler operating parameters according to the load. The gas-fired boiler is affected by less factors, so the size of burner valve can be adjusted according to the load, which is easy to realize automatic control.
