During the coal boom of the s, slurry pipelines were proposed as an alternative to rail transport. Coal would be crushed, then mixed with water to create a slurry and sent via pipeline to its destination, where the mixture was dried, then burned.
When in the pipeline, the slurry moved along at a leisurely four miles an hour. " Coal Water Slurry (referred to as ˝CWS ˛) is an environment friendly coal based liquid-fuel that can be used to replace petroleum.

I responded that I actually don’t know much about it. From a quick read just now, it sounds like a great improvement over the dirtiest forms of coal. Coal Water Slurry / Carbon Slurry Fuel (CWS) CWS is a mixture of finely milled coal or other carbonaceous materials with water or an aqueous emulsion: CWS = Coal (58% 70%) + water emulsion (29% 40%) CWS has almost the same viscosity as masut (heavy fuel oil) what makes it suitable both for pumping on short and long distances and for spraying into a boiler via specially designed nozzles.
As a new-type fuel in place of oil base, coal-water slurry is a high-tech product developed after the world oil crisis, serving as a new member of the fuel family. Coal-water slurry is manufactured by means of coal, rich in reserve and cheap in price, as the major material after being ground and refined in [ ].
The project involved preliminary and detailed design of a 1 tpd pilot plant, its construction and operation, and system studies of potential applications.
Top of Page. Coal-Water Slurry Fuel in Low-Speed Diesel Engine. We analyzed the burning of coal-water slurry fuel in a low-speed diesel engine. Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.
Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of y: carbon. 4C2. Coal Water Mixture Production Technology (CWM) Technology overview 1. Coal slurry overview ˜ The fact that coal is a solid causes some challenges; it requires more complex handling than a fluid does, environmental measures must be undertaken to prevent the dispersion of its dust, and a lot of space is required to store it.

A Joint Venture has been formed to acquire and commercialise technology specialising in the manufacture and combustion of Activated Coal Water Fuel (“ACWF”) from low ranking black and brown coal which can be used as a high quality, low cost feedstock replacement for energy producers of coal water slurry (“CWS”), pulverized coal and heavy industrial oils.
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 gives other benefits.

The shock wave carries a large amount of energy which creates strong shear, collision and cavitation effects thus causing particles in the slurry reduce to an ultrafine size.
As a result, when used in conjunction with coal water slurry grinding, the coal water slurry can be effectively pulverized and its fluidity improved. What is CWM. Coal Water Mixture (CWM) is an advanced method to increase the coal’s economical values.
CWM is a combination of coal, water, and additive substances mixture. CWM is a fuel mixture of pulverized coal and water with the help of additives forming a homogeneous viscous suspension during storage, transportation and combustion.The co-slurrying technology of coal and organic wastewater, which achieves the simultaneous disposal and utilization of wastewater, has attracted extensive attention in recent years.
The emission of coal gasification wastewater causes serious environmental hazards, because of its large amount, high organic content, and high toxicity.
