2. Gas consumption of 5 tons gas boiler

The hourly gas consumption of a 5 ton gas boiler is 361.8m3, how to calculate it? The calculation formula of the gas consumption of the gas boiler is: gas consumption = boiler thermal power × 3600s ÷ natural gas calorific value ÷ boiler thermal efficiency. The thermal power of a 5-ton gas boiler is 3.5MW and the thermal power when using natural gas as fuel is 92%. The natural gas has a high heating value of 39.82MJ / M3 and a low heating value of 35.88MJ / M3. The average value is 37.85MJ / M3, so a 5-ton gas boiler Gas consumption per hour = 3.5 × 3600 ÷ 37.85 ÷ 92% = 361.8m3.


3. Operation cost of 5 tons gas boiler

The boiler operating cost consists of four parts: fuel cost, labor cost, water and electricity cost, and maintenance cost.

Fuel cost: 5 tons of gas-fired boiler consumes 361.8m3 of gas per hour, the total annual cost is: 361.8 × 3.2 × 24 × 92% × 280 = 7157735 yuan;

Water and electricity charges: equipment (fan, feeder, etc.) 50KW, 0.8 yuan per kWh, the total annual cost is 50 × 92% × 0.8 × 24 × 280 = 247296 yuan;

Labor cost: 1 person × 2500 yuan / month × 12 = 30,000 yuan;

Maintenance fee: 3000 yuan;

The total operating cost of a 5-ton gas boiler is 7157735 + 247296 + 30000 + 3000 = 7438031 yuan.

Note: The unit price of natural gas is different in each region, and the configuration of each boiler auxiliary machine is different. For specific costs, please contact our sales team for free.
