Gas-fired boilers use gaseous fuels as the main energy source to meet the needs of industrial manufacturing, production and life by outputting high-temperature steam or hot water.
Air consumption is an important indicator for assessing the overall quality of gas boilers. It is also one of the standards that users measure when purchasing boilers. This data will directly determine the input cost of the boiler operation. Only when the cost is controlled below a certain limit can the data be obtained. More benefits.
How to calculate the gas consumption of a gas boiler?
Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization.
For example, we operate 1 ton gas boiler for 1 hour (full load). The boiler output is 600,000 kcal (fixed value), the natural gas calorific value is 36.22 MJ/Nm3 (fixed value), and the thermal efficiency is 92% (non-fixed value). 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. The specific data depends on the load of the boiler during actual operation.
