The air requirement for each fuel gas is given by the O 2 requirement x 100/21 thus, The theoretical air-gas ratio = 0.93 x 4.76 = 4.43

Read MoreTo 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.

Read MoreThe Carbon Trust recommends that a wood fuel boiler should cover 50-60% of the maximum system load; this translates to approximately 85% of the heat supplied by the biomass system. A peak load boiler (normally the existing oil/gas boiler, but it can be another biomass boiler) covers the extra capacity. Calculating your boiler size

Read MoreMay 28, 2021 · Choosing a suitable size boiler is super important for two key reasons: #1 - It won't meet your homes heating requirements if you undershoot it.. An underpowered (undersized) central heating boiler will struggle to meet the heating demands of your home, resulting in a shortfall of heating to your radiators, hot water to your taps/shower or worse – both.

Read MoreA periodic boiler flue-gas analysis is the best indicator that an adequate supply of combustion air exists. This, and any necessary burner adjustments, should be performed by a trained technician with the proper equipment to measure the amount of excess oxygen and/or carbon dioxide and ppm of carbon monoxide.

Read MoreMar 17, 2015 · Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow; Step 5: Determine Fuel Energy. Fuel Energy = Boiler Energy / Combustion Efficiency; Assumptions. Deaerator provides feedwater near the boiling temperature for the deaerator's set operating pressure. (Saturated Liquid) Steam, Boiler, and Blowdown Pressure are the same.

Read MoreThe 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 …
