Coal-fired steam boiler is a kind of horizontal three-return water-fire tube boiler, which adopts high efficiency and energy saving enhanced combustion technology to ensure the full combustion of fuel. Even better, the volume of the furnace and embers chamber is very large, which is conducive to the embers and settlement of fly ash. The coal fired boiler cost is reasonable, and the steering chamber with coarse dust separation is set at the vent window of the outlet to achieve the purpose of dust removal in the boiler furnace. It reduces the emission of flue gas and makes it reach the target of national environmental protection.

Industrial 10 tons of coal fired steam boiler rated evaporation capacity of 10 tons, rated pressure of 1.25 MPa, steam temperature of 194℃, coal fired boiler efficiency for 60% calculation. The calorific value of coal-fired steam boiler is 4300Kcal /kg, the price is 450 yuan/ton, one hour of coal consumption is 2326kg, then 10 tons of coal-fired steam boiler 1 hour operation cost is 2326Kgx450 yuan /1000=1046.7 yuan/hour. The annual operating hours of the equipment are 4000h, so the annual operating cost of the coal-fired steam boiler is 1046.7 yuan/hour x4000= 4.186,800 yuan.

The annual salt consumption cost of this series of coal-fired boilers is 25,600 yuan, and the annual water consumption cost is 100,000 yuan. The total annual salt consumption and water consumption cost = 25,600 yuan + 100,000 yuan = 125,600 yuan. 10 tons of coal fired steam boiler ash treatment 30,000 yuan, vehicle cost 20,000 yuan, oil 20,000 yuan. Equipment maintenance cost of coal-fired boiler 30,000 yuan, coal-fired boiler 1 year environmental protection cost of 50,000 yuan. By calculating the cost = 180,000 yuan + 30,000 yuan + 20,000 yuan + 20,000 yuan + 30,000 yuan + 50,000 yuan = 330,000 yuan. The annual power consumption of a 10-ton coal-fired steam boiler is 38,400 kilowatt-hours. Calculated at 0.8 yuan/kilowatt-hour, the annual power consumption of a coal-fired boiler is 30,720 yuan. Total 10Ton coal fired boiler cost of operation: 4.186,800 yuan + 125,600 yuan + 330,000 yuan + 30,720 yuan = 4.67312 yuan.

This series steam boiler has a high level of automation, with water automatic regulation, low water level interlock protection, high and low water level alarm functions. Coal-fired steam boiler adopts advanced arched design, forming obvious inverted “α” flame, which is conducive to the combustion of inferior coal, and the adaptability of coal is strong. The welding seam of boiler adopts advanced submerged arc automatic welding technology to ensure the welding quality. A dust collector is arranged in the flue at the end of the boiler to ensure that the smoke discharge meets the requirements of environmental protection.

Coal fired boiler cost setting is reasonable and considerate. The control and monitoring instruments are complete, and the boiler is safe and reliable. Coal fired steam boiler is widely used in schools, textile mills, clothing factories, printing and dyeing factories, restaurants, food factories, beverage factories, bean products factory, meat products factory, cannery, winery, pharmaceutical factory, packaging factory, building materials factory, coating factory, swimming pool and other enterprises and institutions.
