Learn MoreOverview Heating Element Design and Calculation. To perform as a heating element the tape or wire must resist the flow of electricity. This resistance converts the electrical energy into heat which is related to the electrical resistivity of the metal, and is defined as the resistance of a unit length of unit cross-sectional area.

Learn MoreRequired heating power of Thermal Management products. In just four steps you can determine the heating performance required for your application. In addition to the ambient temperature, you can also add humidity values into this calculation - depending on whether a minimum temperature has to be maintained or if a specific humidity level must not be exceeded.

Learn MoreThe amount of heating surface determines the kilowatt rating of a boiler. Calculate the kilowatt rating by multiplying the heating surface in square metres (m2) by 10. 1 m2 of heating surface = 10 kW. (10 m2 = 100 kW, 100 m2 = 1000 kW, etc.) Go To Top How Do I Find The Heating Surface Of My Boiler? Check the manufacturer's nameplate.

Learn MoreSizing a heating system for a greenhouse is not an enormously difficult task requiring complex calculations. True, there are as many formulas as there are growers, but the basic principle remains the same to warm the greenhouse in the most efficient manner. Determine the total exterior surface area

Learn MoreThe formula for the heating surface of a Industrial Steam boiler is measured by multiplying outside Diameter x 3.14 (pi) x length x number of tubes.

Learn MoreDissipation heat loss is defined as the ratio of heat dissipation from the boiler surface to heat input of the boiler . In this paper, the calculation was limited to boiler's proper part, and heat dissipating capacities of all the components were determined indirectly by measuring the surface temperature and ambient temperature .

Learn MoreHVAC COOLING LOAD CALCULATIONS AND PRINCIPLES Sensible Heat Gain is the energy added to the space by conduction, convection and/or radiation. Latent Heat Gain is the energy added to the space when moisture is added to the space by means of vapor emitted by the occupants, generated by a process or through air infiltration from outside or adjacent areas.

Learn MoreSteam, 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.
