1.why choose us?

      our company is a reputable provider of  coal water slurry fule steam boiler with high quality and best service,

we are responsible for your choice.

2.  Application Scope:

 

Coal-water slurry (CWS) can be used in place of oil and gas in any size of heating and power station. CWS is suitable for existing gas, oil, and coal boilers. 

 

2.  Feature and advantage of coal-water mixture fired steam boiler  

1. CFB coal water slurry fired  Stable operation and low emission:Coal water slurry fluidization system realizes the low temperature combustion; avoid coking, unstable operation, poor security problem of Coal-water slurry atomizer system.
2. CFB coal water slurry fired   High efficiency:cyclic burn cluster of coal-water particle, achieve a high efficient performance reach over 89%.
3. CFB coal water slurry fired   No need for slag remover: fluidization combustion mode blow ash through the flue duct to the dust filter
4. CFB coal water slurry fired   Long life span water coal slurry pelletizer machine: High quality atomization coal water slurry burner can use 1500h, but fluidization coal water slurry boiler do not need vulnerable and short lifespan burner, which means long life span.
5. CFB coal water slurry fired   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 (from CaO to CaSO4) , which is simple structure and low cost.
6. CFB coal water slurry fired   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.
7. CFB coal water slurry fired   Broad Fuel Adjustivity Range: the boiler can adjust for different type Coal-water fuel and load range can be set 30% to 100%,
8. CFB coal water slurry fired   Low cost and requirement for Coal-water slurry :Wide adaptable for Coal-water fuel reduces the requirement for Coal-water manufacture, which reduce the Coal-water cost.
9. CFB coal water slurry fired   Simple and stable accessory: SHFS series (CWS fluidization system) do not need expensive burner, fault liability CWS atomization gun, complex high pressure air and CWS system, which make the whole system simple and reliable.
10. CFB coal water slurry fired   PLC control system

Fuel	Fuel Type	Coal	Coal Water Slurry
		5300Kcal	4500Kcal
	Fuel Price(Reference)	780RMB	800RMB
Operation Cost	Thermal Efficiency	68%-73%	≥88%
	Burnout Rate	83%-85%	99%
	Cost for 1t Steam	165.85RMB	160.82RMB
	Desulfuration Cost	25RMB	10RMB
	Water, Electric, Maintenance cost	30RMB	30RMB
	Composite Cost	220.85RMB	200.82RMB
Operation Cost		Low burnout rate, low thermal efficiency, high desulfuration cost, So , the cost is higher	High combustion rate, thermal efficiency, in-furnace desulfuration,,SO, the cost is lower
Floor Space		Coal storage yard, slag storage yard, coal transport equipment occupy large space	CWS transport in closed tank, no coal and slag storage yard, small space occupation
System Comparison		Include Loader, Crusher equipment, complicate operation, high cost for labor cost and maintenance	Compact design, pipe transporting, few accessory, high automatic control, easy to operate
Environment protection comparison		Serious primary pollution , and secondary pollution during production or coal and slag storage yard, emission is high, can not reach the emission standard of Government	Totally closed operation system, emmision is much lower than Government requirement.
Summary		The main advantage of fluidized bed coal water slurry boiler is energy-saving, environmental friendly, small space occupation. So the cost of fluidized bed coal water slurry boiler is much lower than coal fired boiler.
