    额定蒸汽压力,并不是说锅炉只要生产蒸汽就行了,蒸汽跟蒸汽还是有区别的,每个企业有每个企业用汽的标准。就以发电站来说,发电站的汽轮机需要多大压力蒸汽都是有要求的,若压力过高可能损坏汽轮机机组,若压力过低可能根本带不动汽轮机。所以选用合适的额定蒸汽压力也非常重要。
    Rated steam pressure, is not to say that so long as the production of steam boiler, steam with or have difference, each have each enterprise by the standards of the steam. Take, for instance, power station steam turbine power plants need how much pressure steam is required, if the pressure is too high may damage the steam turbine unit, if the pressure is too low may not bring the steam turbine. So choose a suitable rated steam pressure is also very important.
    额定蒸发量,企业选用多大的额定蒸发量应根据企业自己的需求量。比如说企业需汽量不大却选一个大额定蒸发量的蒸汽锅炉,生产出来的蒸汽根本用不完,那只能白白浪费钱。若需汽量很大却选小蒸发量的锅炉,最后造成蒸汽供小于求,那只能采用锅炉改造或者增添新锅炉,这样的话最终的成本要比一次到位直接选择合适的锅炉高很多。
    The rated capacity, the enterprise should choose how much rated evaporation capacity according to the enterprise's own demand. Such as enterprise need to steam quantity is not big but choose a big rated capacity of steam boiler, to produce steam to spare, it can only be a waste of money. If large amounts of steam are required yet choose small evaporation of boiler, finally cause steam demand less than supply, that can only be the retrofit boiler or add new boiler, so the final cost than a place to choose the appropriate boiler directly.
    热效率,一个好的锅炉除了额定蒸发量大以外还需要拥有较高的热效率,很多企业为了图便宜选用了低效率的锅炉,短期内会很实惠,但时间一长会发现效率低的锅炉燃料消耗量也很高,单位燃料产汽量也很低,这样时间一长会非常的亏。

    A good boiler thermal efficiency, except rated evaporation is big also need to have high thermal efficiency, many enterprises in order to pursue cheap chooses the low efficiency of the boiler, in the short term will be very cheap, but a long time will find fuel consumption is also high, low efficiency of the boiler unit fuel steam production rate is low, so that a loss will be very long time.
