Studies On Zonguldak Coal

Abstract

In this work, the carbonization of Zonguldak coals at 400 -1150’C in an inert atmospher has been investigated. The amount, density, the heating values and the combustion of solid products obtained from both slow and sudden heating of coal have been investigated. The calorific values of cokes are inversly proportional with temperatare where as the apparent densities are directly proportional. There is not much diffe- rence between the amounts and heating values of coke obtained from sudden or slow,regular heating processes of coal. These processes have also been observed through Differential Thermal Analyses, (DTA). The semicokes obtained at lovv temperatures burned much easily than the cokes obtained at high temperatures. Besides, the burning temperatures and the excess of air inerease the rate of burning of coke vvhich has been observed through TGA experiments
