Read MoreThis type of boiler works up to maximum pressure of 17.5 bar and steam capacity up to 10 kg/sec. The fire tube boiler has the advantage of lower initial cost, compact design, and easier operation. On the other hand, they have a risk of explosion, large water volume resulting in poor circulation, as well as more time is required for steam to reach the desired pressure.

Read More2015/3/17 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
