  • Mathematical Model of a Flash Drying Process

    The paper presents a basic model of the flash drying process, as it is applied in a number of industrial applications, and illustrates this by means of a particular application the drying of subbituminous coal. Besides its economic importance, that application is representative of those where the product is combustible, so that the drying needs to be conducted in an inert atmosphere, which is The Moisture in the Coal is both these put together and is the "Total Moisture." A coal sampled at the mines having a moisture of 20 , after storage for a few weeks, when entering the boiler can have moisture of only 8 . If the Coal sampled at the mines has an HHV of 18800 kJ/kg the same coal at the boiler will have a higher HHV.

    Combustion of solid fuels is dominant source of energy for the generation of heat and electric power. In places, where coal is not readily available, heavy fuel oil or natural gas is used in power station boilers. Natural gas is a premium fuel and, because of its relatively high price, it was used in The coupled gas-solid description was achieved by a Eulerian-Lagrangian approach. The coal combustion model is divided into the drying process, devolatilization, oxidation of the volatile components and the oxidation of the residual carbon.
