Waste flue gas desulphurization in coal combustion from Ugljevik by the wet process

Abstract

This paper describes the process of waste flue gas desulphurization (FGD) formed in combustion [1] of brown coal from Ugljevik. For the purposes of development the technology of waste flue gas desulphurization (W) in coal combustion from Ugljevik, the experimental development of technology was approached in the laboratory conditions. For experimental work, an apparatus was designed for combustion the coal samples in a closed system with projected measuring points for measuring the composition of waste flue gases. The wet method was used for desulphurization FGD, i.e. the absorption of sulfur dioxide (SO2) in the limestone suspension. The advantage of this desulphurization method is as follows: possession a large amount of raw material for S absorption, relative small investments to prepare the absorption suspension, very simple method of S absorption of EDC, verified in operation [2], high efficiency, obtaining a potentially useful by-product, possibility of application in large plants. .
