Coal-fired high efficiency coal szl boiler not only seriously polluted air, which produces a large amount of waste water sludge can also cause serious water pollution and soil contamination. To protect the city of Tongren green water blue sky, since 2014, led by the city of Tongren City, Guizhou Bureau of Quality Supervision, of 10 steam tons / hour within built-up areas and Tongren City High-tech Zone, Economic Development Zone, Tai Lung range and below, in Guizhou tobacco industry limited liability company Tongren cigarette factory, Tongren City, drug rehabilitation centers, Tongren Wantong construction and development Co., Ltd. and other 36 enterprises of coal-fired boilers to carry out an intensive diagnostic investigation. One by one on the ground to verify the registration, and the companies signed an undertaking to ban coal-fired boilers eliminated; to effectively reduce the burden on enterprises, according to the spirit of the document, to take the initiative within the time limit or eliminate the use of coal-fired boiler unit to switch to clean energy, the after review and acceptance Municipal Environmental Protection Bureau, according to the amount of coal-fired boilers hour evaporation reward, award criteria tons of steam per 30,000 yuan subsidy.
Up to now, the city of Tongren out of 36 coal-fired boiler units, a total of 43.051 tons of steam, an award subsidies 1,291,530 yuan, so far, the city of Tongren jurisdictions total phase-out of all coal-fired boilers, and lay a good foundation for the creation of ecological civilization demonstration area.
Biomass high efficiency coal szl boilers, Henan gas boilers, coal-fired boilers contrast due to environmental pollution problem is serious, the national intensify pollution, especially coal-fired boilers because of incomplete combustion, low thermal efficiency, high pollution emissions, become the primary target of the boiler regulation . Coal-fired boilers due to the low initial investment cost by the majority of enterprises of all ages, in fact, in many ways the point of view, coal-fired boiler is not the best choice. 1, the beginning of investment costs: inputs from the perspective of initial purchase of the boiler, the same tonnage boilers, gas boilers generally highest in Henan, followed by biomass boilers, coal-fired boilers finally. 2, operating costs: the operating costs in terms of the highest Henan gas boiler, followed by coal-fired boilers, biomass boilers and finally, the price of gas prices in various regions are not the same, but much higher than the biomass and coal, biomass price and coal price difference is not big, but because of the low thermal efficiency of coal-fired boilers, coal-fired boiler running costs are higher than the biomass boiler. 3, environmental protection: From the environmental point of Henan gas boiler is undoubtedly the most environmentally friendly, followed by biomass boilers, coal-fired boiler is again. Henan gas boiler fuel is natural gas, biomass fuel boiler is biomass or biomass particles compact, emissions of coal-fired boilers is the largest. 4, Application areas: geographically speaking, Henan gas boiler apparently allow the use of any region, but due to the uneven gas supply, even in some places did not open the gas pipeline, this time biomass boilers to be the best choice, because biomass fuels is still relatively environmentally friendly, because biomass is processed from agricultural and forestry waste such as sawdust or straw fuel. As for coal-fired boilers, in some areas has been limited, it does not allow installation of a coal-fired boiler, due to the different areas of environmental protection standards are not the same, allowing the use of what kind of boiler main contact your local EPA shall prevail.
9.4MW YLW coal-fired thermal oil heater for textile industryThermal oil heaters provide heat energy for the production process of dyeing, drying and printing. Noor Fatima Group is one of the major players in manufacturing and exporting woven fabrics, garments and home textile's products in Pakistan, catering to customers all over the world. The the long-time use of the company’s previous high efficiency coal szl boilers results in performance degradation and potential risks of operation. Considering the higher running and maintenance costs, the company decided to eliminate obsolete boilers and purchase one new set of high efficient thermal oil heater. After thorough intercommunion with ZOZEN’s project leader, the company was deeply impressed by ZOZEN’s high-quality products and rich practical experience, and ultimately chose to cooperate with ZOZEN. ZOZEN offered the company the 9.4MW YLW solid fuel thermal oil heater. This kind of thermal oil heater features wide adaptability of fuels, including bituminous coal, lean coal, anthracite and many other types of coal. The heat exchange surface adopts square coil tube structure, which features more sufficient heating surface and higher thermal efficiency. Simultaneously, advanced measurement and control systems of oil temperature, smoke temperature and oil pressure ensure stable operation for a long time.
Compared with traditional high consumption and high pollution coal fired boiler,the oil fired boiler is more widely used in the industrial production. The fuel oil used in the oil fired boiler reduce the consumption amount , the pollutant discharge as well as the fuel cost.
