How to calculate the operating cost of 10 tons gas boiler? Many people care about this problem, in order to enable users to more clearly understand the operating costs of natural gas boilers, the calculation method of operating cost is listed:
1. Gas consumption: gas consumption (per hour) = gas boiler power * time / fuel calorific value / gas boiler heat value utilization.
Power of 10 tons gas boiler is 7MW, the fuel calorific value calculated according to 35.53MJ / Nm3, boiler thermal efficiency 90%. Therefore, 1 hour consumption of 10 tons natural gas boiler = 7MW * 3600s / 35.53MJ / Nm3 / 90% = 788m3 / h.
Fuel costs: 788m3 / h * gas price.
2. Electricity costs: general power consumption include burner, water pump, electric control cabinet, water treatment equipment, according to data provided by the engineer/hour is about 130 degrees, 130 * industrial electricity price.
3. Labor costs: 10 tons natural gas boilers, equipped with one management staff , two shifts of four homework personnel, one water treatment staff, one regular part-time maintenance staff .
4.Water: gas steam boiler to produce 10 tons of hot water needs 10-11 tons of water./
5. Maintenance costs: This includes the annual inspection of boiler, daily cleaning, warranty and so on.
