### Steam Calculators: Boiler Calculator - Energy

Mar 17, 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.

Jun 15, 2007 · A= total surface area of the heat exchanger. A simple starting point is to assume a gas velocity thru the bank of 50-60 fps, and the UA = 1.5 *WgCp,g ( this is equivalent to an NTU = UA/WCp = 1.5 ). The number of tubes operating in parallel to yield a tubeside water velocity of 10-15 fps. A more accurate method is the e-NTU method, but I think
