Gas boilers generally refer to natural gas boilers, which are the most common boilers used by heating companies in China today. In fact, many boiler manufacturers do not understand the calculation of gas consumption of gas boilers. Today, this article uses the calculation of gas consumption of 10 tons of gas boilers as an example to introduce Let's take a look at the calculation method of gas consumption for gas-fired boilers.
When calculating the gas consumption of a gas boiler, it depends on the low calorific value of the gas, because the quality of natural gas supply in different regions is different, the quality of gas boilers is different, and the amount of mixed air is different. The calculation of gas consumption of gas boilers should clarify the thermal efficiency value of gas boilers. If the boiler has a higher thermal efficiency value, its gas consumption will decrease, and vice versa.
The unit of boiler thermal power is "MW", 0.7MW is equivalent to 1t/h
Taking a 10t/h gas-fired boiler as an example, that is, 10×0.7=7MW, if the calorific value of natural gas is 35170kJ/m³, the calorific value is calculated as follows:
7MW=7×10J/s=7×3600×10kJ/h
Natural gas required for 1h=7×36×10/35170=716.520m³
When calculating the gas consumption of a gas boiler, the calorific value of natural gas and boiler efficiency should be fully considered, so that the calculated value can be in line with the actual situation. The gas boiler of the Fangkuai boiler has a large heating area and stable boiler parameters. The flue gas condensing recovery device at the tail of the boiler ensures the exhaust gas temperature of the boiler, which makes the boiler high in thermal efficiency and can more fully save boiler fuel under the same conditions.
