Get a QuoteSteam, 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 a QuoteFuel fired by (rounding) is 9,070 kg/h or 20,000 lb/h, which has to be dealt with by a set of fuel feeders and grate. Since the fuel is coal, the dumping and reciprocating grates are unsuitable and only the spreader stoker is the choice. Taking a nominal throughput of 2.5 tph or 5000 lb/h for each mechanical feeder, four feeders are adequate.
