Raw coal sampling system

November 22nd, 2013, Published in Articles: Energize

When monitoring the efficiency of a combustion process, it is important to know and understand the nature of the coal being burned. Generally, a proximate analysis will include the following: heat value; moisture content; hardness (Hard Grove index); sulfur content; ash content and volatility. These parameters are essential when optimising the combustion process at coal-fired power plants and large boilers, and are identified by taking representative samples from each coal batch.  M & W Asketeknik’s RCS sampling system lets the operator extract and prepare representative samples of the coal for laboratory analysis. The results of the laboratory tests are used for calculating the payment due for each batch of coal supplied; adjusting the coal flow to the mills; calculating the amount of by-products from each batch of coal; calculating the emissions from each batch of coal; and calculating the blending of various coal batches to obtain maximum output from the power plant.
