Large diameter meters are more often used in water supply and drainage projects. Small and medium caliber instruments are commonly used in solid-liquid biphasic and other difficult to measure fluids or high requirements, such as measurement of paper industry pulp and black liquor, non-ferrous metallurgy slurry, coal slurry, chemical industry, strong corrosive ...
Coal washing is a process through the impact of water flow, raw coal with different components and specific gravity is separated into different grades. ...
The hydrophobic aggregation of fine particles in high muddied coal slurry water in the presence of four quaternary ammonium salts of 1231(dodecyl trimethyl ammonium chloride), 1431(tetradecyl trimethyl ammonium chloride), 1631(cetyl trimethyl ammonium chloride) and 1831(octadecyl trimethyl ammonium chloride) was investigated through the measurement of contact ...
What is “coal-water fuel”? Coal-water fuel (CWSF or CWS or CWF) is a fuel which consists of fine dispersed coal particles, water and plasticizing agent. ...
Raw materials with high dispersion, good homogenization and strong stability are conducive to the stability of the temperature and air pressure of the predissociation system. Coal powders with low water content and high fineness can improve the combustion speed to fully burn the coal powders, improve the calcinations temperature and ensure the ...
One prime example of this tension is the country’s coal use and water supply. According to a new WRI analysis, more than half of China’s proposed coal-fired power plants are slated to be built in areas of high or extremely high water stress. If these plants are built, they could further strain already-scarce ...
Safe, affordable and accessible water is regarded as one of our planet’s scarcest natural resources. This is particularly true on the African continent, where water insecurity is often an everyday reality. At the same time, equitable access to water is fundamental to life and human health and well-being. South Africa already struggles with water scarcity, and it is predicted that the ...
Poorly planned or managed coal seam gas (CSG) exploration or extraction activities pose considerable risks to both groundwater and surface water systems. ...
