### Blog - HOW TO CALCULATE NATURAL GAS CONSUMPTION

Heating Air with Natural Gas . Many air heating applications use steam or hot water coils to heat the air. If you are considering a change to natural gas here is a quick estimating formula to calculate the gas flow rate. CFH =< (CFM ) X (°F OUT - °F IN) > ÷ 800. An example- Heat 1600 CFM (cubic per minute) of from 50 F to 150 F. CFH ...

### Gas consumption of the floor boiler: how much it consumes ...

WITH coaxial chimney the value of efficiency also increases - cold air from the street is heated by a heated exhaust pipe.Due to the second circuit there is of course an increase in gas consumption but in this case the also serves not one but two systems - heating and hot water supply.

Excess Air. A boilers excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess levels can result in being used to heat the rather than transferring it to usable energy.

### How to reduce the gas consumption of gas boilers ...

(3) The boiler has a serious air leakage. Excessive cold air enters the furnace and the oxygen content of the flue gas rises. When the smoke oxygen meter detects that the oxygen content of the flue gas exceeds 8% excess will appear and the heat loss will increase. (4) The quality is lowered and the concentration is lowered.

### How to Check Gas Consumption of the Boiler

Mar 24 2020 · Let's understand more about boiler efficiency and common methods used for calculations of gas consumption. The initial cost of a boiler is usually less than its time to time maintenance and other associated expenses. Quality boilers tend to consume less energy demand less maintenance and cost less than traditional boilers in the long run ...

### 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

Excess Air. A boilers excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy.
