Get a QuoteSince 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 = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)

The simple formula for water is System Delivered BTU = 500 x GPM x System Water Temperature Change. Let's take a look at the formula to see what each piece of it means to help you understand it better. The BTU multiplier in the formula is 500.

Converesely, if we only use half the heating power, 1.75kW, it will take twice as long to heat up to desired temperature, ie, 2 hours. If we only have a 1kW element available, we will expect a heat up time in excess of 3 hours.

Get a QuoteA company who owns a 300 HP steam boiler would approximately pay anywhere from $300 to $600 each month to treat. The difference in cost would depend on run time, water quality, and how much steam is lost and not recovered as condensate return. As the cost to treat rises, lower quality make-up water, as well as a low amounts of condensate return

Get a QuoteMar 13, 2016 · Hi John, it takes the same amount of energy to heat water from 48 degrees to 52 degrees as it takes to heat water from 58 degrees to 62. But when the state of water changes from solid to fluid (e.g. -2°C to + 2°C) or from fluid to gas (e.g. 98°C to 102°C) this does not hold true any more.

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.
