The characteristics of four tons fuel boiler are introduced
介紹4噸燃油鍋爐特性指標(biāo)及定義
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噸燃油鍋爐蒸發(fā)量和熱功率：蒸汽鍋爐容量的大小通常額定蒸發(fā)量來表示。額定蒸發(fā)量是指在額定參數(shù)(壓力、溫度)，燃用設(shè)計(jì)燃料并保證設(shè)計(jì)效率的條件下，連續(xù)運(yùn)行所應(yīng)達(dá)到的最大蒸發(fā)量(單位時(shí)間產(chǎn)汽量)，應(yīng)此也成為額定出力或銘牌蒸發(fā)量，用符號(hào)“D”表示，單位為t/h或kg/s.電站蒸汽鍋爐也可用與汽輪發(fā)電機(jī)組配套的熱功率，即kw或mw來表示。
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、蒸汽或熱水參數(shù)：蒸汽鍋爐生產(chǎn)蒸汽的參數(shù)，是指鍋爐出口處蒸汽的額定壓力(表壓力)和溫度，對(duì)生產(chǎn)飽和蒸汽的鍋爐，一般只標(biāo)明蒸汽壓力，用符號(hào)“P”表示，單位為MPa，對(duì)生產(chǎn)過熱蒸汽或熱水的鍋爐，則需標(biāo)明壓力和蒸汽或熱水溫度，給誰溫度是指進(jìn)省煤器的給水溫度，如無省煤器時(shí)即指進(jìn)鍋爐鍋筒的水溫度。溫度用符號(hào)“t”表示，單位為°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、受熱面蒸發(fā)率和受熱面發(fā)熱率：蒸汽鍋爐的受熱面積是指鍋筒或受熱面與煙氣接觸的金屬表面積，用符號(hào)“H”表示，單位為┫，蒸汽鍋爐的受熱面蒸發(fā)率是指每平方米受熱面每小時(shí)所產(chǎn)的蒸汽量，用D/H表示，單位為kg/┫h。
