• ### Steam Calculators: Boiler Calculator

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.

The feed water supplied to the boiler is equal to the sum of the steam leaving the boiler and the blowdown discharged from the boiler. The feed water rate can be estimated using the following equation: Feed Water Rate (gal/day) = Steam Generation Rate (gal/day) ÷ [1 (1 ÷ Cycles of Concentration)]

• ### Boiler conversion from steam to hot water? - DoItYourself ...

Feb 08 2017 · Not really accurate. Steam at 0 pressure moves very quickly about 50 to 60 ft second and water moves 2-4 ft a second. Moving water will heat slower to a given temp than still water. The radiator will get hotter with steam and take longer to cool off. A good operating steam boiler/system will operate evenly quietly and efficiently.

• ### Boiler Capacity - Engineering ToolBox

Since the amount of steam delivered varies with temperature and pressure a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (h g - h f) m (1)
