The accuracy of coal testing results helps in maximizing recovery, utilization aspect and optimization of coal preparation plants. The coals to be used for metallurgical purposes has the most stringent requirements like low ash and sulphur content, and bituminous rank coal. However, the thermal plants can utilize high ash coals, but the composition of ash plays a significant role in deciding the boiler and operating parameters.
Identification of the chemical composition of coal has a strong influence on its combustibility. Identification of sulphur content in coal and reducing sulphur in the fuel combusted also will reduce sulphate formation and fine particulate emissions and help to improve visibility by reducing regional haze. Testing results in a variety of improvements to plant operations, which directly affect the profitability of a coal plant, its ability to meet environmental requirements, and its ability to avoid future economic risks.
One of the major issues that are faced while designing a boiler is the behaviour of ash during the combustion process and management of coal ash. This can be prevented by testing a bunch of coal and specifying its properties. Coal testing help with a complete analysis of the quality of coal so that you can gauge the performance of the boiler design.
With the increasingly stringent environmental policies, the accuracy of coal analysis results help in optimizing disposal and storages of reject coal, coal slurries, fly ash and slag. Poor quality coal produces NOx, SOx and fly ash in reasonably large quantity as compared to good quality coal, so the pre-treatment before processing and disposal can enhance the economy of the plant. The coal analysis results provided by us help coal producers and processing industries in deciding the cleaning equipment, parameters, and probable amount of by-products. The optimization of by-products and pollutants not only save the environment from poisonous hazards also enhances the economy of the plant.
