Learn MoreMay 16, 2018· Calculate the amount of time it takes to heat the water by dividing the power used to heat the water, which was determined to be 1.867 with the heater element rating, listed in kW. So if your heater element rating was 3.6 kW, your equation would look like this: heating time = 1.867 ÷ 3.6, or heating time =0.52 hours.

Learn MoreFor example, if a furnace is rated at 100,000 BTUs and is 80% efficient, then the heat output will be 80,000 BTUs (100,000 x .8). However, if a furnace is rated at 100,000 BTUs and is 92% efficient, then the heat output will be 92,000 BTUs (100,000 x .92).

Learn MoreMar 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.

Learn MoreThe thermal efficiency of a boiler specifies the effectiveness of the heat exchanger of the boiler which actually transfers the heat energy from fireside to water side. Thermal efficiency is badly affected by scale formation/soot formation on the boiler tubes. Direct and Indirect Boiler Efficiency

Learn MoreAug 29, 2017· The calculation of boiler's fuel efficiency boiler should consider the consumption amount of fuel used, so it is very appropriate to be used as a point of boiler economic analysis. Direct Method There are two popular methods for calculating the fuel efficiency of the boiler; the direct method and the indirect one.

Learn MoreHeating BTU Calculator When shopping for heaters, many people make the mistake of choosing the wrong size for their actual needs. Given all the different options available for heaters –– space, vented, gas, console, and more –– narrowing down the choices can be a great way to ensure that you are choosing the best option.

Learn MoreAug 29, 2017· Boiler Efficiency Calculation: a complete guide. Calculating the combustion efficiency of the boiler is not difficult, we just need to reduce the total amount of heat energy released by thermal energy burning that passes out through the stack (chimney) divided by the total heat energy.

Learn MoreUse btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow. This is an average industrial boiler.
