Coal Water Slurry - SlideShare

Both coal-oil mixtures and coal-water slurries are suitable for heating and steam-raising applications generally as an alternative to heavy fuel oil although they can be used as engine fuels. Coarse coal (> 1 mm diameter) - water slurries can be used as feedstocks for gasification plants and as a feedstock for direct coal injection into blast

Coal Water Slurry Boiler – Enneng Machinery

Industrial tests of coal water slurry combustion in the 20 tons per hour steam output and 60 tons per hour steam output oil fired boilers have been carried out since 1981 in China. Nowaday, a project of burning coal water slurry in the 230 T/H utility boiler in Baiyanghe power plant has been made and several of the retrofit works have been done.

Water-coal slurry as an alternative to natural gas and

The coal-water slurry (CWS) is a potential new form of fuel for application in power boilers and industrial furnaces. The single suspended coal-water slurry droplets have been burned in hot gas streams to reveal their basic nature of evaporation and heating processes. Temperature measurement and microscopic observation are performed.

Production of coal-water slurry fuel with AVS - avs

Coal water slurry fuel (CWSF) represents a feasible method for burning coal in boilers designed for oil and natural gas. However, oil- or gas-fired boilers at Army plants cannot be converted to bum CWSF unless the fuel burner is redesigned. This evaluation of test and prototype burners can help Army engineers design Army CWSF conversions.

Aug 12, 2016 · Water-coal slurry (abbreviated as CWS, CWSM, CWM) is a mix of coal, water and plasticizer. Modern day CWS is coming into use in heat generation facilities as an alternative to natural gas and heavy fuel oil. The main advantage of this fuel is its cost efficiency, since the calorific value of CWS is no less than that of the more expensive natural gas and fuel oil, with a much lower cost.

Coal-water slurry: A status report - ScienceDirect

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.
