1. A 1ton gas fired boiler consumes about 75 m3 of natural gas in one hour.
 
2. It mainly depends on the calorific value of the gas and the thermal efficiency of the boiler.
 
3. The calculation formula of gas consumption of gas boiler is: gas consumption of gas boiler (per hour) = power of gas boiler * time/calorific value of fuel/utilization rate of calorific value of gas boiler.
 
4. The power of a 1-ton gas-fired boiler is 0.7MW, the calorific value of the fuel is calculated according to 35.53MJ/N per cubic meter, and the thermal efficiency of the boiler is between 90%.
 
5. Then, the 1-ton natural gas boiler consumes 1 hour = 0.7MW*3600 seconds/35.53MJ/Nm3/90%.
 
6. Therefore, it is obtained through the theoretical data formula: the gas consumption of 1 ton natural gas boiler is about 75 cubic meters.

If you want the natural gas boiler you use to be more energy-efficient, you can think of ways to improve the operating thermal efficiency of the boiler.
