Coal-water slurry boiler is just in recent years due to the rise of the product, but also the current relatively hot, some units have their own skills and strength or they do not over-exaggerate their own strength, high-tech brand name of coal-water slurry to promote their products. At the same time due to fewer users, the user a low level of knowledge of products, choose the more blindly, resulting in failure of investment projects or effect is not satisfactory, and losses. From many years we have engaged in a traditional coal-fired boilers and coal-water slurry (layer burning) oil-fired boilers have great difference. For the user to better selection of products, coal-water slurry boiler below the main points to note when you use set out below, provide reference to use:
A matching on system
A result of coal-water slurry boiler system, supporting more equipment, more control, they need the entire technical system support services, it is very important. Our entire system is divided into: 1. Boiler system: including boilers host, summon the fan, flue gas purification equipment, electrical control equipment, water treatment equipment. The key is to choose the host and the boiler flue gas purification equipment. Combustion product is a result of coal-water slurry boiler flue gas composition of 11 very different from ordinary boilers (such as dust concentration and dust particle size), we specialize in supporting the development of coal-water slurry boiler flue gas purification equipment-specific. 2.
For the slurry system: including coal slurry storage tank; coal slurry mixing filtration devices; to provide Pumps: blast furnace console; coal-water slurry burner and other equipment. We are characterized by: a. Cone coal slurry storage tank design, long-term storage difficult to precipitate. b. discharge slurry and stirring integration of design, and with a mechanical filter. c. advanced, with automatic ignition burners. d. a unique blast furnace console, using combustion control for the pulp, water supply, gas supply centralized control for easy operation. 3. Compressed Air and Oil System: We are matching the best performance and reliability of air compressor screw air compressor rod. 4. Boilers and system equipment control. We have a general and fully automatic
Operational Control are two ways for users to choose automatic control by microcomputer, and PCL control of the boiler to achieve the automatic ignition, the load will automatically be adjusted automatically adjust so the wind plasma.
2 on the coal-water slurry boiler-specific
Our company is coal-water slurry boiler walked three during the R & D-cum-three generations of products.
The first generation of products is a result of coal-water slurry of pulverized coal, water, coupled with a small amount of paste mixed with PPD. In the ignition process must first evaporation, while the evaporation process required to absorb a large number of the hot, tested and calculated, it requires that the fiery red-hot coal with 1.77 times. Evaporation accounts for water, coal and burn time of 6 ~ 8%, coal-water slurry on fire more difficult. Furthermore, if designed to cause excessive coking furnace. Our first generation products are mainly based on the combustion of coal-water slurry to conduct a special design, mainly to resolve the rapid ignition of coal-water slurry, stable combustion problems. But the first generation boiler output widespread lack of
Bottom ash was difficult (with human ash-based), boilers, high-load run-time coke furnace Yi, the system device configuration over and unreasonable and so on. For the products, the above problems, we conducted a second improved product design and improvement, the formation of a second-generation product.
Second-generation products in the boiler to ensure rapid ignition and stable combustion of the premise, we have a boiler furnace, ash equipment, burners, decency equipment, a comprehensive improvement. Part of the furnace to increase the heating surface; an increase of the furnace a dust removal device, so that the original boiler emissions targets greatly reduced; used to effectively prevent the particular coking furnace structure; some type of Boiler economizer to the air preheater. Ash increases strength instead of the hydraulic means to achieve fully automatic operation out of the boiler ash. An increase of the ignition burner. System equipment added to flue gas purification equipment: The family of devices integrated design.
Second-generation products to contribute to the basic guarantee for the boiler, thermal efficiency indicators, while indicators of the boiler arch fully meet the national requirements of the second-class district requirements.
Third-generation product in 2005, we have been in full pulverized coal boiler coal-water slurry boiler mode third-generation product development products. And adopted many advanced technologies, which include advanced, suitable for coal-water slurry combustion furnace structure; furnace aerodynamic field in a reasonable design, reliable and reasonable out of slag ash plant; humane, intelligent, then the operation and control systems and so on. The third generation far more than one in Shandong, Shanghai, Guangdong, Zhejiang and other places put into operation, running, fully meet the design requirements.
3. With regard to coal-water slurry
Coal-water slurry boiler fuel for the coal-water slurry, coal slurry need specialized factories for production. According to CWS Center, to the end of 2005 only the country a total of 29 coal-water slurry plant, design capacity of 10.42 million tons / year, mainly in Shandong, Shanxi and other coal-producing province and Guangdong province in the economy. But the coal-water slurry as a national priority to encourage and support the development of the technology industry, recently around the country will be rapid development.
Coal-water slurry based on the nature, is divided into coal coal-water slurry, economical coal-water slurry, coal-water slurry gasification and so on. Performance indicators and quality throughout the coal-water slurry is also a larger difference in price there are differences, the state has formulated a " <GB/T18855-2002> "The standard provides technical requirements, and had I ~ III-level classification. Therefore, when the user must purchase manufacturers provide a "coal-water slurry test report." CWS has durability pulp mill does not occur in general commitment to a two-month hard precipitation.
I have been provided by the use of coalwater slurry boiler for more than 90 of the national production of coalwater slurry pulp mill, adaptability is better, but different. Recently the company set up in Zhejiang province is first coalwater manufacturers took the lead in environment protection and energy technology Jinhua Co., Ltd., specialized in production and supply and demand of coal-water slurry, pulp and raw materials chosen for their quality of washed coal, since most of the pulp and the most advanced techniques and technology, made of coal-water slurry quantities of better. According to the transport distance and the user can choose the company directly for syrup, but also by the users and my company recommended protocol for the direct pulp pulp mill.
