    In this case, the "from and at 212°F" steaming rate is 3,450 lbs/hr, but the net steaming rate is only 2874 lbs/hr—17% less than the "from and at 212°F" steaming rate. The effect of feedwater heating is pertinent in all applications and should always be considered.Get Price

  • How Watertube Boilers Outperform Firetube Boilers - Miura

    Water tube boilers blow fire tube boilers away in regards to efficiency. Water tube boilers require far less water to function, and at the same time, they also have a higher rate of steam generation than fire tube boilers. This helps to reduce the amount of water and fuel necessary to make a water tube boiler run compared to the alternative option.Get Price
