A reasonably well-insulated shell or water-tube boiler of 5 MW or more will lose between 0.3 and 0.5% of its energy to the surroundings. This may not appear to be a large amount, but it must be remembered that this is 0.3 to 0.5% of the boiler's full-load rating, and this loss will remain constant, even if the boiler is not exporting steam to the plant, and is simply on stand-by.Get Price
3/6/2020 · Fire tube boilers have great steam quality due to large steam volume inside the boiler and large surface area for steam release. Due to that these boilers required long startup time. Generally maximum capacity of these boilers is 17.5 kg/cm2 and with a capacity of 9 MT/HR.Get Price

Fire tube boilers also tend to have lower Annual Fuel Utilization Efficiency (AFUE) ratings, which is the ratio of how much heat transfers to the water versus how much goes out of the flue. Older fire tube boilers can have AFUE ratings as low as 50 percent, meaning only half the heat energy turns to steam heat and the rest is wasted.Get Price
