Get a QuoteBoiler Capacity Calculation with Heating Surface Area--ZBG GPM = BTU/hr8.33lb./gal x 60 min x ^t F. The formula indicates a water temperature of 60 F. However, since 60 F water is too cool for a hot water heating system and too warm for a chilled water system

Get a QuoteFor this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5. This number represents the thermal energy rate required to turn 34.5 lbs of water at 212 F to steam in one hour. Learn More Hot Water Boiler

Get a QuoteThis constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.

Get a QuoteSteam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 C

Get a QuoteVolume is the amount of water you wish to heat up this is in litres. Delta T is the change in temperature ie heating water from 10 °Celcius to 50 °Celcius would be a Delta T of 40 °Celcius. PowerKW is the power level of the heat source ie a 30 kw boiler would be 30 kw.

Get a QuoteInfo on Water treatment The make-up water must be deaerated by heating it in the feed water vessel. This increases own use required by the steam boiler system. Direct consumers can, for example, be found in drying processes during humidification, when heating

Get a QuoteThis is another calculation on heating water, this time relating hot water flow rates and boiler power. It too ends with a handy rule which can be applied without reference to a manufacturer's manual. Suppose we want a hot water flow rate of, say, 9 litres per minute

Get a QuoteBoiler BTU Calculator given Flow and T Hot water boilers do not experience any phase change in the heating process so the calculation is different than for steam boilers. Since there are no phase changes, the latent energy is not utilized in hot water boilers.

Get a QuoteWater-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate.

Get a QuoteBTU/HR to Boiler Horsepower Calculator The BTU/hour to Boiler Horsepower calculator is used to help size both steam and hot water boilers. This calculation translates the heat transfer input requirement to BHP. To do so, we divide the BTU/hour by a constant of 33,475.

Get a QuoteIn the UK, mains cold water is generally assumed to be 4°C whilst 'hot water' for a domestic system is usually around 60°C (this will avoid scalding). So the cold mains water needs to be raised by 56°C within the hot watertank. As 1 litre of water needs about 1.16 watts to raise it through 1°C in an hour, a 120 litre tank of cold mains
