how to calculate the natural gas boiler cop value

How to calculate the gas consumption of a gas steam boiler

The output of a 1 ton boiler is 700,000 kcal, and so on. The output of a 10 ton boiler is 7 million kcal. Second, the fuel consumption calculation formula. Fuel consumption = boiler output ÷ fuel calorific value ÷ boiler thermal efficiency.

How Efficient is a Condensing Boiler? (2021) | GreenMatch

Mar 24, 2021 · The higher the coefficient of performance (COP) of a condensing boiler, the lower the heating system temperature will be. Thus, a condensing boiler will be more efficient if it is coupled with water-based underfloor heating with the flow temperature …

Industrial Boiler Efficiency Calculation & Factors

Since COP is an apples to apples ratio of Watts of Output divided by Watts of Input, this means, in order to get your air conditioner's or heat pump's COP of cooling performance all you have to do is simply convert the EER into COP, or multiply your EER by .293, which will convert the oranges to apples ratio into an apples to apples ratio of Watts Out divided by Watts In, or COP: Let's go ahead and do this for our 3 …

How To Calculate Natural Gas Boiler Consumption--ZBG

The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3, pressure 8-10Kpa, and theoretically, the gas consumption of boiler heat = boiler calorific value÷ (Calorific value of natural gas x Boiler thermal efficiency )= 2400 000 Kcal / (8500Kcal * 0.94) =297m3/h, here we take 4 tons of natural gas boilers for example, then the boiler gas …

Coefficient of Performance Calculator

Calculate coefficient of performance (COP) of a heating system in which the TCOLD value is 10K and the THOT value is 200K. COPHEATING= THOT/(THOT - TCOLD)= 200/(200-10)= 1.05. So the COP is 1.05 in this case. Related Resources. Thermal Efficiency Calculator
