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 china coal fired steam boiler prices 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.

To implement the central authorities on the construction of ecological civilization and major decisions and plans, "the Jiangsu provincial government office on efforts to reduce coal year 2019 work" (Su Zheng Ban Fa ﹝ 2019 ﹞ 45) requirements, carry out the "263" special action, continued reduction of non-electric industry (including captive power plant) coal consumption, in the middle of this month, Nanjing people's government Office issued the "Nanjing 2019 work program minus coal." Compared with the 2016 base, the city of Nanjing in 2019 non-industrial enterprises in the coal power industry regulations reduction target is 3.88 million tons, 13.3 million tons less than total control.
"Plan" clearly requires, Nanjing will further reduce the implementation of industrial coal, increase the elimination of backward production capacity and inefficient excess capacity Yajian efforts to accelerate the implementation of the chemical industry regulation to enhance and accelerate the implementation of Nangang, Meishan Steel coke production capacity out of work year after year, to speed up eliminate backward production capacity of coal, cement clinker production capacity in an orderly exit.
At the same time, to promote structural reduction of coal, the implementation of ecological and environmental protection requirements of the Yangtze River economic belt along the Yangtze River to promote the orderly relocation of key enterprises and industrial transformation and upgrading, the city's coal consumption structure and strive to achieve a fundamental change; accelerate the aging coal-fired non-compliance unit outage work.
According to the requirements, "plan" put forward, Nanjing will also strengthen reduce coal progress warning. Less coal combined monthly schedules, reducing the monthly publication Coal risk warning, the cumulative assessment carried out in accordance with the red, yellow and green three levels. Less progress of coal coal consumption does not exceed a custom schedule for the green light; cumulative coal consumption over a predetermined schedule within 2% of the yellow light, will be issued urge communicated, to be a reminder and a warning; the cumulative coal consumption over a predetermined plan of 2% or more for the red light, will be relevant area (park) conduct interviews, and urge them to implement technical, administrative and other measures to encourage companies to reduce coal consumption over consumption.
Factors that affect factors superheated steam temperature changes affect food factory superheated china coal fired steam boiler prices plant food temperature variation effects superheated steam boiler temperature variation food factory, 1, 2 changes, and the air volume ratio of 3 changes, burner fuel properties and 4, 6, 7, change the saturated steam temperature change and desuperheating water flow operation mode change in water temperature in the pulverizing system 5, the heating surface cleanliness variation boiler load variations. Change in fuel volatile carbon content, calorific value and the like: 1. Variations in the nature of the fuel. When the roughening coal, fuel combustion in the furnace a long time, the center of the flame increases, the steam temperature. When the fuel water is increased, the heat absorption of water evaporation furnace, the furnace temperature is lowered, the increase in humidity, but also increases the volume of the flue gas, the flue gas flow increases, reducing the superheater heat radiation, convection superheater heat absorption is increased. 2. And change the air volume ratio: when increasing the oxygen content of the furnace, the low temperature due to heat absorption of cold air, the furnace temperature is lowered, the furnace outlet temperature. At a total gas flow is constant, a change will also cause shifts air distribution steam temperature. When a low flow rate is insufficient, part of incomplete combustion of pulverized coal, the flame center is moved upward, the furnace exit gas temperature. 3, changing the operating mode of the burners and pulverizing system: operating system will result in an upper pulverizing the steam temperature is increased, the swing angle of the burner changes, the change in center of the flame, steam temperature changes.
