1 ton gas boiler running on natural gas cost calculation users in the purchase of boiler equipment, in addition to considering the quality and price of the boiler, operating costs are also most concerned about. As a large industrial boilers special equipment, operating costs after start-up is not low. Today, small series to calculate the running costs of natural gas boiler, to help you better understand the gas boiler. On the whole, operating costs including natural gas boiler: fuel costs, utilities, labor costs, maintenance costs. Run 1 ton gas factory price coal steam boiler 1 hour example to calculate the cost of running the boiler. 1, the cost of gas, 1 tons of gas steam boiler steam rated the amount of 1 ton / hour, different in different parts of the integrated natural gas quality and other factors, natural gas consumption in the 70-80 cubic meters / hour, according to our understanding, now on the market of natural gas the price of 3.5 yuan / cubic calculated (prices slightly floating), gas consumption is calculated according to 75 cubic meters. Gas Cost: 1 × 75 × 3.5 = 262.5 / hour 2, the cost of water, gas steam boiler 1 tons an hour to convert 1 ton 1 ton of steam into the water, because the middle of demineralized water and sewage water treatment needs, 1 ton of normal use of the steam boiler takes about 1.1 tons of water, according to our understanding, the market price is now floating around 3 yuan / ton. The cost of water: 1.1 × 3 = 3.3 yuan / hour 3, the cost of electricity, the main fuel gas steam boiler 1 ton electric burner position and pumps, other mostly weak. Burner using power 1.5KW, use the pump power of 1.4KW, other weak power use of about 1KW. During normal use of the boiler, electrical power is 0.65 times the full load power, calculate the total electric power (1.5KW + 1.4KW + 1KW) × 0.65 = 2.535KW. The electricity is $ 1 / calculation. Electricity costs: 2.535 × 1 = 2.535 / hour 4, labor costs, fast boiler into gas boiler market is the intelligent automatic high boiler plant, only coal fireman who patrol back and forth without the need to manually add fuel high intensity work. Fireman who according to 3000 yuan / month wage, working 12 hours a day, in two shifts. Labor costs: 3000 × 2 times / 30 days / 24 h = 8.33 yuan / 5 hours, gas boilers, and maintenance costs of model SZS fast WNS square type gas boiler in the factory after the quenching treatment and a full range of testing, failure rate Very low, response, post-boiler maintenance costs are reduced. If it is a gas station one ton steam boiler, the maintenance cost is about 2000 a year on it. According to 365 days a year, eight hours a day of computing time, the boiler operation cost per hour is: 2000/365/8 = 0.68 yuan. Combining these five aspects of the cost of inputs, it can be summed up 1 ton operating cost per hour of gas boilers: 262.5 yuan / hour + 3.3 yuan / hour +2.535 yuan / hour +8.33 yuan / hour +0.68 yuan / hour = 277.345 yuan / hour . In addition Xiao Bian also like to remind you that the above calculations are based on the cost of using boiler operating at full capacity, but due to the use of the boiler boiler enterprises have different needs, it may not be fixed to keep running at full capacity. Therefore, some of the actual running costs of the boiler than it is now calculated 277.345 yuan low.
