9824 coal boiler tph
At any time, domestic more and more attention to environmental protection, coal-fired steam 9824 coal boiler tph suffered heavy damage. Relatively speaking, gas-fired steam boiler is favored by many users. In recent years, the state has also vigorously promoted the use of gas-fired boilers. What are the benefits of a coal-fired steam boiler? Let's discuss it with you today. Gas-fired steam boilers and coal-fired steam boilers occupy half of the market, showing a trend of court resistance, but in the long run, gas-fired steam boilers will obviously become the only dominant market. No, please look! 1. Procurement cost: it is clear that gas-fired boilers are well ahead of ignition in terms of technology and ancillary equipment The coal boiler is equipped with a special gas burner. Take 1 ton steam boiler as an example, gas-fired boiler is about 30% higher than coal-fired boiler. 2. Construction cost: this cost mainly comes from boiler room. Because of the coal-fired steam boiler supporting equipment more, boiler room construction should invest more funds. The auxiliary equipment of gas-fired boiler has few auxiliary equipment, automatic control operation, automatic alarm and automatic protection function, which not only saves the cost of building, but also is safe and reliable. After connecting the natural gas pipeline, the burner will automatically supply gas, which can effectively save staff costs. Coal-fired boilers also have to pay some of their employees' salaries because they need to participate in the coal program . 3. Fuel costs: you can see this clearly by looking at the actual specific fuel prices at each location. The fact is that the amount of coal burned per hour is much higher than the amount of gas. 4. Environmental costs: with the need to protect the environment, the audit of coal-fired boilers is becoming more and more stringent. Gas-fired steam boilers are more and more widely used due to economic operation, environmental protection and energy conservation, as well as government policies.
In recent years, Siyang County town chrysanthemum industry as part of the ecological projects to enrich the people in the choice of chrysanthemum drying equipment, the county Environmental Protection Agency proposed to replace coal-fired 9824 coal boiler tphs to electric boilers idea. Part chrysanthemum growers is objected that the idea costly and cumbersome, but after analysis and explanation of the Environmental Protection Agency and the power company personnel, electrical boilers have a deeper understanding of the use of electric boiler can not only improve drying chrysanthemum chrysanthemum quality and product phase, it did clean, safe, and there are various government subsidies, while coal boiler if the government out of the use, post-investment costs will be higher. At present, the boiler "electricity for coal" action has been noticed.
In recent years, Siyang County uphold the "gold and silver mines that lies to" development concept, vigorously implement alternative energy projects, alternative energy gradually extended to grain drying, drying fruits and vegetables, herbal drying and bathroom, hotels, restaurants, businesses and other industries. Siyang county party secretary said: "Winning 'Battle of Blue Sky', shouting slogans alone are not shouting to the sky, or from the 'coal to electricity,' 'oil to electricity' these specific things to start, through the implementation of alternative energy engineering, elimination of high energy consumption, low-energy-efficient equipment, the progressive realization of ecological priority, green development goals. "
Since 2016, the county completed a total alternative energy companies, service unit 686, phase out coal boiler 1336 units, to complete alternative energy electricity 256.69 million kwh. Energy saving alternative to business spending, reduce production costs and improve their efficiency and realize a production of "zero emissions" to protect the party clear water and blue sky. In mid-November, Siyang County was selected as "the second batch of national ecological demonstration counties civilization."
Through estimation: If the exhaust gas temperature of 150 ℃, when the excess air ratio from 1.5 to 3.0 cases, the combustion is generally bituminous coal, anthracite 9824 coal boiler tphs, heat losses from about 5% to 10%, reducing the thermal efficiency of the boiler nearly 5 percentage points. While the chain grate boiler excess air ratio was mainly due to leakage caused by the grate, but also accounted for a large proportion of the furnace leakage, strict plugging wind, to improve boiler thermal efficiency, reduce coal consumption, save energy resources it is very significant. Before plugging the wind, the first thing leakage test boiler.
Is more feasible briquettes may be employed, it will be used after vaporization, the residue after burning so that less amount of the exhaust gas is small too heavy discharged from the combustion, and the combustion heat value of the coal after vaporization is relatively high, so the use of more cost-effective in the heating 9824 coal boiler tph.
