The characteristics of four tons fuel boiler are introduced
介绍4吨燃油锅炉特性指标及定义
Steam boiler evaporative capacity and heat power: the capacity of steam boiler is usually rated as the amount of evaporation. Rated capacity refers to the rated parameters (pressure, temperature), under the condition of the gasification of fuel and ensure design efficiency, continuous operation should reach the maximum evaporation (steam production rate per unit time), should it also be a rating or plaque evaporation, with the symbol "D", said the unit for t/h or kg/s. power station steam boiler can also be used to form a complete set of steam turbine unit thermal power, namely kw or mw.
4吨燃油锅炉蒸发量和热功率：蒸汽锅炉容量的大小通常额定蒸发量来表示。额定蒸发量是指在额定参数(压力、温度)，燃用设计燃料并保证设计效率的条件下，连续运行所应达到的最大蒸发量(单位时间产汽量)，应此也成为额定出力或铭牌蒸发量，用符号“D”表示，单位为t/h或kg/s.电站蒸汽锅炉也可用与汽轮发电机组配套的热功率，即kw或mw来表示。
2, steam or hot water parameters: the parameters of the steam boiler to produce steam, is refers to the pressure rating of the boiler outlet steam pressure (table) and temperature, to produce saturated steam boiler, steam pressure, in general only with symbol "P", said the unit for the MPa, the production of superheated steam or hot water boiler, need to indicate the pressure and steam or hot water temperature, temperature of the who refers to the feed water temperature of economizer, such as no economizer namely into the boiler drum water temperature. Temperature with the symbol "t", said the unit for ° C.
2、蒸汽或热水参数：蒸汽锅炉生产蒸汽的参数，是指锅炉出口处蒸汽的额定压力(表压力)和温度，对生产饱和蒸汽的锅炉，一般只标明蒸汽压力，用符号“P”表示，单位为MPa，对生产过热蒸汽或热水的锅炉，则需标明压力和蒸汽或热水温度，给谁温度是指进省煤器的给水温度，如无省煤器时即指进锅炉锅筒的水温度。温度用符号“t”表示，单位为°C。
: 3, the heating surface evaporation rate and surface heating rate of the steam boiler heating surface is refers to the drum or metal surface area in contact with the flue gas of heating surface, with the symbol "H", said the unit for ┫, steam heating surface of boiler heating surface evaporation rate is every square metre per hour of steam, expressed with D/H, the unit is kg / ┫ H.
3、受热面蒸发率和受热面发热率：蒸汽锅炉的受热面积是指锅筒或受热面与烟气接触的金属表面积，用符号“H”表示，单位为┫，蒸汽锅炉的受热面蒸发率是指每平方米受热面每小时所产的蒸汽量，用D/H表示，单位为kg/┫h。
