Coal washing. Coal washing is a method of clean coal technology that purifies the coal before it is burnt. Coal washing occurs in a coal preparation plant and prepares the coal to be burnt by ridding it of its impurities, meaning that once it is burnt it produces a cleaner gas, eliminating the need for carbon capture and storage.
In its original usage, the term "Clean Coal" was used to refer to technologies that were designed to reduce emission of pollutants associated with burning coal, such as washing coal at the mine. This step removes some of the sulfur and other contaminants, including rocks and soil. This makes coal cleaner and cheaper to transport.
Coal washing represents the most important step of coal preparation. The raw runofmine coal requires selective qualitative and quantitative analysis for finding the most suitable operating conditions for cleaning coal to obtain the desired quality. Among these analyses, the washability test is .

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
Aug 31, 2017· How to Conserve Coal. Coal consumption isn''t just a matter for industrial companies and train conductors. Coal is one of the natural resources used most commonly to create electricity for homes and businesses. Of the one billion tons of coal burned in America each year, nearly 90 percent is used to create electricity.
Large quantities of water are often needed to remove impurities from coal, in the process is known as coal washing. For instance, in China, around onefifth of the water used in the coal industry is used for this process. This process helps reduce air pollution, as it eliminates around 50% of the ash content in the coal.
Coal washing, also known as coal preparation, has been dealt with from a system approach view point. This helps to simplify the process and to explain the different components of the system. A coal preparation plant is a system consisting of different subsystems, broadly crushing, prewashing, washing .
Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration
Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and settle. Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and particulates.
