Four factors to consider when choosing steam boilers
Steam boiler is the vital equipment used in daily life or industrial production. While there are four factors people should consider when they decide to choose a new steam boiler.
1, the steam boiler outputSteam boiler output, the steam boiler evaporation, buy steam boilers, boiler rated output should be close to the maximum of your production or living with steam or heat. Or livelihoods of about 80% of the steam boiler Rated evaporation is more appropriate, due to pipeline damage, boiler scale, soot and other issues will make the boiler can not operate optimally.
2, steam boiler feed water temperatureOn the market the same amount of boiler plate evaporation, its water temperature 20 ℃, 60 ℃, 90 ℃, 100 ℃, 105 ℃ and other five as much. The same boiler plate evaporation, due to the high and low water temperature, will have a greater difference between the actual evapotranspiration its boiler. For example: 20 ℃ water temperature of the boiler output and 100 ℃ water temperature there is a big difference in the output. 20 ℃ water temperature of the boiler output is 114% 100 ℃ water temperature of the power output. Small capacity boilers generally are used at room temperature water, how you will raise water temperature to 90 ℃ or 100 ℃ before entering the boiler it? (Except for the thermal oxygen required)
3, boiler working pressureRated steam pressure boiler plate should be greater than the sum required for the production of steam piping resistance and working pressure. Do not neglect the steam pipe resistance, due to its higher rated steam pressure saturated steam temperature is higher.
4, boiler heating areaCompare boiler heating area (heat transfer area) is an important choice (design) parameters boilers. Because the heated area of boiler general output, strong overload capacity, whereas output is small. Same boiler capacity, heating area is relatively large, relatively low exhaust gas temperature, boiler efficiency is relatively high, the heat from fuel combustion is more fully utilized, fuel consumption is low.
