  • How to calculate the gas consumption of the gas boilers

    Sep 12, 2019 · According to the actual situation of the boiler, the calculation is carried out. Then, the gas volume required for the operating hours of a 1 ton natural gas boiler = 0.7 MW * 3600 s / 36.22 MJ / Nm3 / 92% = 75 m3 / h. Note: The actual power of the boiler is generally not equal to the rated power, so the consumption of gas is only a rough estimate.Learn More
