Boiler Efficiency

Jul 22, 2013 · If you have read our other blogs you will note that we are advocates of using a HEAT LOSS CALCULATOR to determine your heating system boiler size and radiation requirements. However, when replacing an existing boiler in a hydronic (forced hot water) system a shortcut method is available, subject to some qualifications. Measuring your total radiation (baseboard registers, radiators, cabinet […]

plant how do i calculate the boiler heat duty

Dec 31, 2011 · If you have a stream where more than one phase exists then you can calculate the heat duty using the equation below: Q = Qg + Qo + Qw. Where; Q – is the overall heat duty or total heat transferred, Btu/hr or kW. Qg – is the gas heat duty or heat transfer rate, Btu/hr or kW. Qo – is the oil heat duty or heat transfer rate, Btu/hr or kW

Boiler Efficiency: Introduction and Methods of Calculation

To do so, we divide the BTU/hour by a constant of 33,475. This 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.

WHAT SIZE BOILER DO I NEED? - MEASURE YOUR RADIATION

Jun 18, 2014 · This isn't about heat loss. This is about heating a LOT of metal. So . . . is the boiler a cold-start boiler (which means you have metal to heat every time it starts), or is the boiler operating on outdoor reset (where there would be less of a temperature rise each time). All of this changes depending on how cold it is outside, of course.
