Energy saving appliances will gradually capture the market
Procurement cost of coal, sulfur dioxide pollution, smoke pollution has been the use of coal-fired boiler business concerns. Beginning in March of this year, some enterprises began to use a city known as “coal-fired energy-saving and emission reduction of sulfur dioxide catalytic combustion technology” clean coal combustion technology, energy saving achieved good results.
Recently, the reporter went to Ming Yang Biochemical Technology Co., Ltd. Guangxi, the boiler room, I saw a spray measurement system installed in the boiler of the coal conveyor belt next to two staff members are next to the preparations. This reporter saw a burning coal catalyst at constant speed through the system of quantitative control in the two coal conversion to coal belt spray catalyst. It is understood Ming Yang biochemical company on October 13 this year, try out the technology to become the city’s first and only company currently using the technology business.
“Using this technology, using the same coal, furnace temperature increase than the previous 30 to 50 degrees Celsius, 780 degrees Celsius from the previous to the present 830 to 840 degrees Celsius, while the chimney of soot emitted than the previous white more, more light. “monitor the company’s boiler Ban Bang Liu told reporters. As Guangxi local coal generally low fat, 4000 kcal below the low quality coal is low volatile, high sulfur content, sulfur dioxide pollution is serious. Procurement of high-quality coal from abroad is bound to increase procurement costs and procurement difficulties, the traditional practice of not only the installation of desulphurisation large investment, long construction period, the installation has finished running costs are very high. Both companies have been looking for an effective energy conservation, but also to achieve better economic benefits of technology. This year, I heard that coal-fired energy and reduce emissions of sulfur dioxide catalytic combustion technology in other provinces to achieve good results, the technology is not only saving coal effect, but also to reduce sulfur dioxide emissions. Per ton of coal can save about 10 yuan, the company is generally the amount of coal each year from 30,000 to 50,000 tons, so that companies can save hundreds of million of costs. The sulfur dioxide emissions, they could save a lot of excessive sewage charges. So they through the Municipal Economic Commission and the technical units linked, in the October 13 agreement with the technical units, the first trial period, the effect well, it would be officially used.
“Catalytic Combustion of coal sulfur dioxide emission reduction and energy saving technology is a clean coal combustion technology, and includes comprehensive management of smoke, ash comprehensive utilization of a comprehensive solution.” Guangxi Jin Yuan Dong and general manager of Wenfeng Chemical Technology Co., Ltd., said, The technology by increasing the combustion rate of coal-fired furnace to burn more fully achieve the energy saving purpose, general coal saving rate of about 8% to 15%, 25% reduction of sulfur dioxide, nitrogen oxide emissions by about 17%. It can also be reduced to different degrees slag and fly ash content in fuel. Moreover, the technology can effectively reduce the formation of coal-fired boiler scale coke and coke In addition, cleaning, improving working conditions of the burner, increase heat transfer efficiency of the boiler while the boiler corrosion and reduce wear to extend equipment maintenance cycle, reducing maintenance costs.
It is understood that the technology is applicable to all CFB boilers, pulverized, and other chain furnace boiler, coal mines, or cement kilns and other industries and various industrial coal-fired boilers. Meanwhile, no transformation of the process of using the boiler and other equipment, with a special pump exhaust catalyst mixed with coal, installation is easy, not the normal operation of existing facilities and bring any negative factors, input costs not more than 20,000 element.
Wenfeng also explained that the main component of coal combustion catalyst from the carrier phase and catalytic activity of a number of auxiliary substances and accelerant composition does not contain explosive components, it is not the normal operation of combustion equipment to cause any harm. Existing users in the long-term use did not occur during the boiler caused by the abnormal stop accidents catalyst, catalyst additions are safe and reliable to meet industrial requirements.
June 2008, coal-fired energy and reduce emissions of sulfur dioxide catalytic combustion techniques classified by the National Development and Reform Commission first focused on energy saving energy reduction of 50 to promote energy efficient technologies, which can effectively alleviate the rising price of coal, coal the adverse impact of supply for enterprises to create a direct economic benefits, also contribute to energy conservation.
