CWS: architectural ceramics business to choose the best fuel
Reduction in energy-saving, green production, under the new situation, ceramics enterprises energy options in the scientific and technological innovation, scientific and technological progress in the transformation of the turn, prices, environmental protection, security prices are Tao choose one of the important elements. Concern in this coal-water slurry technology, use, promotion, application experts, provide a little information.
First, what is the CWS CWS
the seventies of the twentieth century have occurred in the world oil crisis, the emergence of an alternative to a new type of fuel oil. First appeared in the United States and Europe, used in power plants in the early eighties into China. CWS is a solid-state coal through a certain process into a certain mobility of the solid, liquid two-phase fluid fuels, like oil as it can reduce the storage, transportation, safe and stable long-term continuous combustion, not only to retain coal combustion characteristics, but also possess the characteristics of heavy oil applications. Say concise CWS is a kind of water, coal mixture.
Second, coal-water slurry in the building ceramics enterprises
use of coal and coal-water slurry is a certain proportion of water by mixing, add a small amount of additives, Add to ball mill in milling, grinding, etc. to a certain degree of fineness slurry release, screening, stored in a mixer to the slurry pond. CWS
Tao construction in China has been standing on the wide use of ceramics in China several major bases in Foshan, Guangdong province, Zibo, Shandong, Fujian Jinjiang, Minqing, Sichuan Jiajiang, as well as Henan, Hebei, Jiangxi, Guangxi, Inner Mongolia, Jiangsu and other places as well as Vietnam, Indonesia and other countries have substantial ceramics factory in the use of spray-drying tower, all achieved good economic benefits, and local environmental protection (as compared with heavy oil as fuel) made a contributions. With the coal-water slurry technology and coal-water slurry combustion equipment and technology, through different combination of coal-water slurry combustion equipment, the current coal-water slurry can be applied to the sophisticated and non-glazed ceramic tiles have glaze on tiles and polished Micropowder .
in accordance with the use of coal-water slurry equipment manufacturers feedback, the coal-water slurry technology in spray-drying tower to run stable operation condition is better than heavy oil. The proportion of oil and more secure, powder production, and quality of reliable, fully able to meet the ceramic production of the technical requirements.
three, the economic benefits of coal-water slurry
to use alternatives to coal-water slurry of heavy oil in a well-known brands of Foshan ceramic production Group (production Polished) four 4000-type spray-drying tower for Example, the cost-effectiveness analysis of incidental and natural gas as well as the gas furnace production comparing the effectiveness of water gas.
for comparative analysis of cost-effectiveness data based on:
(1) ceramic powder hot water evaporation total: 3550KJ/KG, (2) the production of coal-water slurry calorific value of coal: 25500KJ / KG, the price: 580 yuan / ton; coal slurry concentration 55%, coal-water slurry production processing fee 50 yuan / ton (water, electricity, artificial, additives, etc.), coal-water slurry calorific value: 14025KJ/KG, Price: 369 / ton; (3) The calorific value of heavy oil: 39710KJ/KG, price: 3400 yuan / ton; (4) natural gas calorific value: 35112KJ / m 3, price: 1.8 yuan / m 3; (5) water-gas calorific value : 5852KJ / m 3, production of water gas lump coal price: 760 yuan / ton, coal lump coal per kg 3 m 3, water-gas prices (including processing costs): 0.28 Yuan / m 3. (6) spray-drying tower system of work 24 hours a day, 30 days per month, every year for 10 months.
① the use of coal-water slurry (each spray-drying tower 4000 annual cost)
(water evaporation evaporation × total hot water / coal slurry calorific value) × water coal plasma spray-drying tower unit price × working hours per year = (4000 × 3550/14025/1000) × 369 × IO × 30 × 24 = 2689950 of $
② the use of heavy oil (per 4000-type spray-drying tower annual cost)
(water evaporation evaporation × total hot water / oil heat value) × × unit price of heavy oil spray drying tower
workers every year for the second time (4000 × 3550 / 39710/1000) × 3400 × 10 × 30 × 24 = 8753865 of $
③ the use of natural gas (per 4000 1000 Type spray dry tower annual cost)
(water evaporation X total evaporative hot water / gas heat value) × day × unit price of gas spray-drying tower
work every time = (4000 × 3550/35112) × 1.8 × 10 × 30 × 24 = 5241285 of $
④ the use of water gas (per 4000 spray-drying tower annual cost)
(water evaporation evaporation × total hot water / hot water gas value) × unit price × water-gas spray drying Tower of work time per year = (4000 × 3550/5852) × 0.28 × 10 × 30 × 24 = 4891866 of $
Based on the above calculation and analysis of data, a 4000-type spray dryer used in each of coal-water slurry as a the proportion of fuel oil to save 69.27%; than 48.68 percent natural gas savings; than 45.01 percent water gas savings. This
Foshan Ceramics Group, the four spray-drying tower by the heavy oil into a coal-water slurry, the annual fuel savings on the near 30 million yuan.
IV CWS environmental protection, security effectiveness
for the production of coal-water slurry of coal in the sulfur content of about 0.6%, and now with the oil refining technologies improve, and now worsening quality of heavy oil, sulfur content are 2.5%, up 4.5 percent higher, the same calorific value, sulfur heavy fuel oil are released from the coal-water slurry of 2.68 times.
as a result of coal-water slurry combustion temperature of 150 degrees with low proportion of oil, so the proportion of coal-water slurry oil combustion have less harmful nitrogen oxides (on the human body and plants very harmful). ceramic production
many now using water gas as kiln fuels, the production of the occurrence of water gas furnace will be essential to containing a large amount of benzene, phenol and other toxic substances in wastewater, is strictly prohibited country emissions, which are ceramics factory is difficult to resolve the big problem, use the waste water produced out coal-water slurry combustion, both non-polluting solution to the problem also can be described as dual.
CWS in the normal, not spontaneous combustion, non-explosive, non-toxic, no dust, gas, water gas contains a lot of explosive gas, and ceramic raw materials workshop complex, improper operation easy problems. The production of water gas generated large amounts of toxic wastewater treatment, the high cost and difficult to complete treatment, and only diluted emissions, not only pollute the environment but also afraid to have entrepreneurial spirit, the national policy.
five coal-water slurry combustion equipment
CWS market the use of ceramic in Foshan, though not long, but the coal-water slurry combustion technology developing rapidly, there has been a variety of water-coal combustion Slurry equipment, currently on the market has the following major coal-water slurry combustion equipment “with a dust collector of water-acetylene equipment such as fine dust collector cyclone type TAIYANFA Stove, Stove cyclone-type dust, dust settlement chamber Stove, without dust collector, such as rotary hot stove. these types of hot gas have the characteristics of these types of devices in Sunflower Fine dust collector cyclone-type reaction Stove manufacturers better, mainly easy ignition, combustion efficiency high, the furnace design, long-term Non-burning furnace coal ash, and its unique style dust TAIYANFA unique structural design, collection efficiency is very high, is fully applicable in the raw materials, semi-finished production, have been dozens of well-known brands ceramics factory to use this equipment, make good economic and social benefits.
