1. Brief Introduction of Coal water Slurry Benefit
l Safe storage and transportation fuel: The presence of water in Zozen reduces harmful emissions into the atmosphere and makes the coal explosion-proof. By converting the coal into a liquid form, delivery and dispensing of the fuel can be simplified.
l Low cost fuel: Because of the relatively low cost of coal when compared to other energy sources, Zozen is a very competitive alternative to heating oil and gas. Depending on geographical area the price per unit energy of Zozen may be 30% to 70% lower than the equivalent oil or gas.
l Cost effective and environmental friendly: Low emissions and low BTU cost (Gcal or MWh) make Zozen very cost effective and environmental friendly fuel for heat and power generation.
2. Coal Fired Steam Boiler Advantage
l Environment friendly, energy saving and, high efficiency: coal combustion efficiency reach above 98%., thermal efficiency reach above 85%
l Wide and simple load adjustment range: load range can adjust from 35% to 100%, economical choice.
l Covering area Saving: Coal water slurry and coal power transport in airtight canning, no dust pollution, no need coal storage yard and slag yard, improve the use ratio of land, save 50% land area.
l Low fuel cost with high intelligent automatic control: save human resource, coal fired boiler need 6-7 worker coal water slurry boiler only need two workers, save fuel beyond 20%. Improve the sanitary condition and alleviate workerlabor
l Substitute fuel for oil and gas:Coal-water slurry boiler has become an ideal substitute for oil and gas fired steam boiler.
l Low temperature combustion: Coal water slurry boiler can heat up to and maintain 900°C-1200 °Cin a very little time, which avoid the Incomplete combustion during the low temperature period, also avoid producing the NOx of oil fired boiler when temperature is above 1300°C
l Clean flue gas emission: Zozen boiler dust emission concentration is about 100mg/Nm3 . which is 1/2 of the national emissionstandard 200 mg/Nm3. ash can be used as material of building and cement after closed dry ash collection system.
3. SHFS Series (Zozen Fluidization System) Feature
l Stable operation and low emission: Coal-water fluidization system realizes the low temperature combustion; avoid coking, unstable operation, poor security problem of Coal-water atomizer system.
l High efficiency:cyclic burn cluster of coal-water particle, achieve a high efficient performance.
l No need for slag remover: fluidization combustion mode blow ash through the flue duct to the dust filter
l Long life span water coal slurry pelletizer machine: High quality atomization coal water slurry burner can use 1500h-2000h, but fluidization coal water slurry boiler do not need vulnerable and short lifespan burner, which means long life span.
l Low cost for desulfuration:Use limestone and silica sand as medium material cooperate with low temperature combustion technology realize the direct desulfuration during Coal-water combustion, which is simple structure and low cost.
l Low consumption for medium material:recycle of limestone increase the use ratio which reduce the supply of limestone and medium material. This system also increases the efficiency.
l Wide Load Adjustable Range:the boiler can adjust for different type Coal-water fuel and load range can be set 30% to 100%,
l Low cost and requirement for Coal-water:Wide adaptable for Coal-water fuel reduces the requirement for Coal-water manufacture, which reduce the Coal-water cost.
l Simple and stable accessory: SHFS series (Zozen fluidization system) do not need expensive burner, fault liability Zozen atomization gun, complex high pressure air and Zozen system, which make the whole system simple and reliable.
l PLC control system
4. Application Scope:
Coal-water slurry (Zozen ) can be used in place of oil and gas in any size of heating and power station. Zozen is suitable for existing gas, oil, and coal boilers.
