Read moreIf your boiler is 2.25 times the size required for the radiators, you may be about 4.5 times oversized for the heat load. This would yield a seasonal efficiency around 52 percent, assuming a steady state efficiency around 78 percent (which is a realistic number for most modern atmospheric steam boilers).

Read more17/3/2015 · 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.

Read moreHeat transfer can be described in the network above, so that the overall heat transfer is calculated by dividing overall temperature difference by the amount of thermal resistance
