Answer (1 of 6): The reason is temperature, the Carnot principle. The higher the hot temperature, the higher the efficiency. Contrary to a Carnot cycle, a real steam (Rankine) cycle is not reversible and the hot temperature is not a constant, but varies in theGet Price
Defective parts in auxiliary machinery may increase the steam requirements for the machinery and thereby cause excessive fuel oil consumption. Worn bearings, defective governors, worn or excessively tight packing, scored or bent shafts and other mechanical defects cause auxiliary machinery to use more steam than would otherwise be required.Get Price
2015/3/17 · 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.Get Price
