Coal water slurry fuel

详情

Coal-water slurry fuel (CWSF or CWS or CWF) is a fuel which consists of fine coal particles suspended in water. Presence of water in CWS reduces harmful emissions into the atmosphere,makes the coal explosion-proof,makes use of coal equivalent to use of liquid fuel and give other benefits. CWS consists of ****0% of fine despersed coal particles and ****5% of water.

Uses:
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. When used in Low Speed Diesels the CWF has resulted in thermal efficiency rating that rivals Combined Cycle Gas Turbines that burn Natural Gas as their primary fuel. It has been suggested that slightly modified modular Diesel engine power plants that burn CWF are economically competitive with Natural Gas fired peaking electric plants in the *0 MWe to **0 MWe range of power supply.

Benefits: 
The presence of water in CWS reduces harmful emissions[clarification needed][citation needed] 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.
Because of the relatively low cost of coal when compared to other energy sources, CWS is a very competitive alternative to heating oil and gas. Depending on geographical area the price per unit energy of CWS may be *0% to *0% lower than the equivalent oil or gas. 
Low emissions and low BTU cost (Gcal or MWh) make CWS very cost effective and environmental friendly fuel for heat and power generation. 
One side benefit of the Coal Water Slurry production process is the separation of non carbon material mixed with the coal before treatment. This results in a reduction of ash content to as low as 2% for the treated Coal Water Slurry Fuel, making it a viable alternative to Diesel fuel #2 for use in large stationary engines or Diesel Electric Locomotives.
