Coal''s dominance of the nation''s electricitygeneration market began to slide as far back as 2009 as a flood of gas from shale formations sent prices for the powerplant fuel crashing, making it a cheap alternative. NRG''s Knox said it would cost "millions" to convert its Limestone plant to gas.
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. Learn how the process works as .
Material Processing Dedusting and Agglomeration. We offer a variety of custom agglomeration equipment for processing coal. Our pin mixers are an ideal fit for dedusting applications. When combined with our disc pelletizers, coal fines can be processed into a pelletized product.. Pug mills (paddle mixers) and briquetters for processing coal fines into briquettes are also available.
