ABSTRACT

Fly ash, generated during the combustion of coal for energy production, is an industrial by-product which is recognized as an environmental pollutant. Because of the environmental problems presented by the fly ash, considerable research has been undertaken on the subject worldwide. Indian coal has a very high ash content, up to over 45%. At this rate, the amount of fly ash to be handled by the end of the year 2012, based on the above generation projections, is approximately 160 million tons of fly ash generated in a year. There is a need to handle this colossal amount of fly ash in such a way that it is productively utilized to whatever extent possible; the balance should be disposed of with minimum harm to the environment. This is possible by utilizing the latest technologies as a solution to this huge disposal problem. The objectives of this paper are to critique the existing dry fly-ash disposal system and identify shortcomings, optimize the existing system, and troubleshoot the specific problems encountered. The scope of this paper is to provide innovative solutions for controlling wear and meet the specified designed rate of disposal by re-engineering the disposal line. The modifications implemented in the system show substantial reduction in frequently observed problems such as excessive erosion/wear due to high velocity, ash flow irregularity due to which the system was not meeting the designed disposal rate, and segregated fly-ash collection for different end uses.
