As long as it is a gas-fired boiler, we all call it a gas-fired boiler. Whether the problem of "gas shortage" exists or not, the air head of low nitrogen gas boiler is absolutely the most prosperous one in recent years. Gas-fired boiler consumption and operation cost have also become one of the main problems of customer consultation. Today, let's give our customers some references on the calculation of gas consumption of gas-fired boilers and their specific values. As the current gas boiler market is dominated by natural gas steam boilers, the calculation of other fuel consumption of gas boilers can be used in the same way.
1, Gas Consumption Calculation of Natural Gas Boiler in One Hour
Formula for calculating hourly gas consumption of natural gas steam boilers: power of gas-fired boilers*time/fuel calorific value/calorific value utilization ratio of gas-fired boilers Taking a 2-ton natural gas boiler as an example, a gas-fired boiler with a output of 1 ton works continuously for one hour at full load, and its design efficiency is calculated by 92%. Then the required gas volume for a 2-ton natural gas boiler operating hours is 1.4MW*3600s/36.22MJ/Nm3/92%=150m3/h.
Note: The actual power of the boiler is not exactly the same as the rated power, so the calculation of gas consumption is actually a rough estimate.
2,Reference of one-hour gas consumption for common tonnage natural gas steam boilers (assumed conditions are the same as above)
| Horizontal gas-fired boiler of 1 ton consumes 75 m3/h of gas in one hour |
1 hour gas consumption of 2 ton fast-loading natural gas boilers is 150 m3/h |
| Gas Consumption of 3-ton Condensed Natural Gas Steam Boiler in One Hour is 225 m3/h |
Gas consumption of 4 ton gas steam boiler in one hour is 300 m3/h |
| Gas consumption of 5 ton natural gas steam boiler in one hour is 375 m3/h |
Gas consumption of 6 ton gas-fired boiler in one hour is 450 m3/h |
| Gas Consumption of 8-ton Natural Gas Steam Boiler in One Hour is 600 m3/h |
Gas consumption of 10 ton gas-fired boiler in one hour is 750 m3/h |
| 1 hour gas consumption of 12 ton gas-fired boilers is 900 m3/h |
1 hour gas consumption of 15 ton natural gas boiler 1125 m3/h |
| 1 hour gas consumption of 16 ton natural gas boiler 1200 m3/h |
1 hour gas consumption of 18 ton natural gas steam boiler is 1 350 m3/h |
| 1 hour gas consumption of 20 ton low nitrogen condensing natural gas boiler 1500 m3/h |
1 hour gas consumption of 25 ton natural gas boiler is 1875 m3/h |
| 1 hour gas consumption of 30 ton natural gas boiler 2250 m3/h |
Gas Consumption of 35 tons Natural Gas Steam Boiler in One Hour is 2625 m3/h |
| Gas consumption of 40 ton gas-fired steam boiler in one hour is 3000 m3/h |
Gas consumption per hour of 45 ton gas fired boiler is 3375 m3/h |
| Gas consumption of 50 ton natural gas boiler in one hour is 3750 m3/h |
Gas Consumption of 60 ton Natural Gas Steam Boiler in One Hour is 4500 m3/h |
| One hour gas consumption of 65 ton large gas fired boiler is 4875 m3/h |
One-hour gas consumption of 75-ton gas-fired power generation boilers is 5625 m3/h |
The price of industrial natural gas and civil natural gas in China is generally 2-5 yuan/cubic meter. As for the monthly cost and annual cost of natural gas consumption of natural gas boilers, the cost of fuel for boiler operation can be estimated by itself.
3,More references for calorific value of boiler gas fuel
At present, the fuel of gas-fired boilers emerges in endlessly, and the determination of fuel calorific value takes a lot of effort, after special calorific value detection. But as long as you know how to calculate the boiler's gas consumption, it will change forever. You can calculate it by yourself or consult the ZOZEN boiler directly online.
