Read MoreBHP = Boiler Horsepower - The boiler's capacity to deliver steam to a system. LB / HR = Pound per hour - Mass flow rate. It is particularly useful when dealing with gases or liquids, as volume flow varies more with temperature and pressure. BTU / HR = measuring energy per unit time - Equal to 1 BTU being output in an hour.

Read MoreMar 17, 2015 · The feedwater flow rate can be calculated from steam mass flow and blowdown rate: Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate; Steam Mass Flow = Feedwater Mass Flow - Blowdown Mass Flow; Steam Mass Flow = Feedwater Mass Flow - Feedwater Mass Flow * Blowdown Rate; Feedwater Mass Flow = Steam Mass Flow / [ 1 - …

Read MoreSteam is then pumped from the top of the boiler to wherever heating is needed. The boiler contains a safety valve that, when the pressure becomes too high due to blockage or overheating, releases the excess steam. Project Description Our engineering team designed a threepass fire tube steam boiler with a capacity of 5000 kg of steam per hour

The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Pressure = 650.6 psig; Quality = 0.00 [Steam Property Calculator] => Specific Enthalpy = 484.9 btu/lbm; Blowdown Energy Flow = Specific Enthalpy * Mass Flow

Read MoreMar 31, 2002 · Spirax-Sarco's excellent steam handbook, as well as many texts/design guides on boiler sizing provide guidance/rules for determining required water surface area for accumulators & steam drums. A wet accumulator is just a steam drum without the fired energy input: think of it as an extension of the steam drum.

Read More• Evaporator: Once through boilers: in once-through boilers the pressure loss of the evaporator is between 5 and 30 %. Forced and natural circulation boilers: the pressure drop in the evaporator part of drum- based boilers does not affect the pressure loss of the main steam/water flow through the boiler.
