As long as it is a gas-fired boiler, we are collectively referred to as a gas boiler. Regardless of whether the problem of "gas shortage" exists, the limelight of low-nitrogen gas boilers is definitely the most prosperous in recent years. The gas consumption of gas boilers and the operating cost of gas boilers have also become one of the main issues for customer consultation. Today, let's first give customers some reference on the calculation of gas consumption of gas boilers and specific values. Since the current gas boiler market is dominated by natural gas steam boilers, the calculation of other fuel consumption of gas boilers can be inferred.
1. Calculation of gas consumption of natural gas boiler in 1 hour
Hourly gas consumption calculation formula of natural gas steam boiler: gas boiler power*time/fuel heating value/gas boiler heating value utilization rate
Taking a 2-ton natural gas boiler as an example, a gas-fired boiler with an output of 1 ton works continuously for 1 hour at full load, and the design efficiency is calculated at 92%. Then the gas volume required for a 2-ton natural gas boiler in operating hours = 1.4MW*3600s/36.22 MJ/Nm3/92%=150m3/h
Note: The actual power of the boiler is generally not exactly equal to the rated power, so the calculation of gas consumption is actually a rough estimate.
2. Reference for gas consumption of common tonnage natural gas steam boilers in one hour of operation (assuming conditions are equal to the above)
1 ton horizontal gas boiler has a gas consumption of 75m3/h per hour | 1 hour gas consumption of 2 ton fast-installed natural gas boiler is 150m3/h |
3 ton condensing natural gas steam boiler 1 hour gas consumption 225m3/h | Gas consumption of 4 tons gas steam boiler in 1 hour is 300m3/h |
1 hour gas consumption of 5 tons natural gas steam boiler is 375m3/h | 1 hour gas consumption of 6 ton gas boiler is 450m3/h |
The gas consumption of the 8 ton natural gas steam boiler per hour is 600m3/h | 10-ton gas boiler consumes 750m3/h of gas per hour |
1 hour gas consumption of 12 tons gas boiler is 900m3/h | 1 hour gas consumption of 15 tons natural gas boiler is 1125m3/h |
The gas consumption of a 16-ton natural gas boiler per hour is 1200m3/h | 18 tons natural gas steam boiler 1 hour gas consumption 1350m3/h |
20-ton low-nitrogen condensing natural gas boiler 1 hour gas consumption 1500m3/h | 1 hour gas consumption of 25 tons natural gas boiler is 1875m3/h |
30-ton natural gas boiler consumes 2250m3/h in 1 hour | 35 tons natural gas steam boiler consumes 2625m3/h in 1 hour |
A 40-ton gas-fired steam boiler consumes 3000m3/h in 1 hour | The hourly gas consumption of the 45-ton gas boiler is 3375m3/h |
1 hour gas consumption of 50 tons natural gas boiler is 3750m3/h | 60 tons natural gas steam boiler consumes 4500m3/h in 1 hour |
The gas consumption of a 65-ton large gas boiler per hour is 4875m3/h | 1 hour gas consumption of 75 tons gas-fired power boiler is 5625m3/h |
The price of industrial natural gas and civil natural gas in various parts of my country is generally 2-5 yuan/cubic meter. Regarding the monthly cost of natural gas boiler and the annual natural gas consumption cost, you can estimate the fuel cost of boiler operation by yourself.
3. References for more boiler gas fuel calorific value
At present, the fuel of gas-fired boilers is endless, and it takes a lot of effort to determine the calorific value of the fuel, and special calorific value detection. But as long as you know how to calculate the gas consumption of the boiler, you can calculate it yourself, or you can directly consult xinli boiler online. The price of industrial natural gas and civil natural gas in various parts of my country is generally 2-5 yuan/cubic meter. Regarding the monthly cost of natural gas boiler and the annual natural gas consumption cost, you can estimate the fuel cost of boiler operation by yourself.
3, more boiler gas fuel heating value reference
At present, fuels for gas-fired boilers are emerging in an endless stream, and it takes a lot of effort to determine the calorific value of the fuel and go through a special calorific value test. But as long as you know how to calculate the gas consumption of the boiler, it will never change. You can calculate it yourself, or you can directly consult Xinli Boiler online.
