You know how the boiler works? Boiler parameters is a main boiler performance indicators, including the boiler capacity, steam pressure, steam temperature, water temperature and the like. Boiler capacity available rated maximum continuous evaporation or evaporation is represented. Rated evaporation under a predetermined outlet pressure, temperature and efficiency, the amount of steam per unit time of continuous production. Maximum continuous evaporation under a predetermined outlet pressure, temperature, per unit time the maximum continuous amount of steam produced. Steam pressure and temperature parameters including steam boiler, generally refers to a superheater, superheated steam pressure and temperature at the outlet of the reheater and superheater if no reheater, saturated steam pressure and temperature at the outlet of the boiler refers. Refers to a water temperature of the economizer inlet temperature, inlet temperature refers drum without economizer. Boilers can be categorized in different ways. Boiler use can be divided industrial boilers, utility boilers, marine boilers and boiler locomotive; by the boiler outlet pressure can be divided into low, medium, high pressure, high pressure, sub-critical pressure, the supercritical pressure boiler; boiler and by water flue gas flow path can be divided into the fire tube boilers, fire tube boilers and water-tube boilers, fire tube boilers and wherein the fire tube boiler and collectively shell boiler; press cycle can be divided into natural circulation boiler, auxiliary boiler cycle (i.e., forced-circulation boilers), and the combined circulation boiler once-through boiler; by combustion, the boiler chamber into the burner, and boiling Stoker furnace. Water vapor system, feedwater heated to a temperature in the heater, the water supply pipe into the economizer, after further heating into the drum, along with the mixing pot of water down to the water wall downcomer inlet header. Radiative heat absorbing soda water formed by the mixture in the riser in the drum reaches the waterwall tubes, the water from the steam separator means, steam separation. The separated saturated steam from the superheater to the upper stream drum, continue to become superheated steam endothermic certain temperature (most of the current 300MW, 600MW unit main steam temperature is about 540 ℃), and then sent to the turbine. In terms of combustion and flue gas system, the air blower into the air preheater is heated to a certain temperature. It is ground to certain fineness in the mill coal, a portion of the hot air from the air preheater carried into the furnace through a burner. Discharging pulverized coal burner and combustion air mixture is mixed with the rest of the hot air in the furnace and release large amount of heat. The hot flue gas flowing through the furnace sequence after combustion, Slag bundle, the superheater, economizer and air preheater, and then through the dust removal device, wherein the fly ash is removed, and finally sent to the chimney by the induced draft fan to the atmosphere.
