1 ton gas and steam boiler operation cost: fuel cost, water and electricity cost, labor cost, maintenance cost;
1. Fuel cost: the gas consumption per ton of steam is 75 cubic meters, the unit price of gas is 3 yuan/cubic meter, and the fuel cost is 75*3=225 yuan;
2. Electricity cost: the consumption is 2.2kwh, the price of electricity is 1 yuan/Kwh, and the electricity cost for one hour is 2.8 yuan;
3. Water cost: the consumption is about 1.1 tons. The price of water is 1 yuan/ton.

4. Maintenance cost: according to 50,000 yuan/year, the cost per hour is about 5.8 yuan.
5. Labor cost: it takes one person, 3000 yuan/person/month, and each person works 10 hours a day, so the cost per hour is about 10 yuan/hour.
It can be seen that the operating cost of a 1-ton gas-steam boiler is mainly the fuel cost, which accounts for about 90% of the total operating cost, and the level of the fuel cost is determined by the thermal efficiency of the boiler.Therefore, users in the purchase of boilers, to do multiple considerations, choose high efficiency, quality stability of the boiler.
