Gasification, coal thermally balanced

Table 10-13. Energy Balance of Plasma-Chemical Coal Gasification by Water Vapor with Heating the Reagents in Thermal Plasma Jets of Other Gases...

Gasification of Coal by Water Vapor in Thermal Plasma Jet. Prove that thermal plasma treatment of coal with water vapor provides not only gasification of the volatile compounds of the coal but also gasification of coke. Use the material balance data shown in Table 10-12. 

As mentioned already in the previous chapter, time does not play a role in the formulation of equilibrium conditions. The mass and energy balances and the maximum conversion rate that can be achieved when the system is in thermal equilibrium are therefore not sufficient to define the dimensions of the best suited coal gasification equipment, which will here be termed the gas generator. A knowledge of how the gasification reactions proceed with time is therefore indispensable. To measure and, wherever possible, calculate this dependence on time is the object of reaction kinetics. Dealing with details of kinetic laws would go beyond the scope and purpose of this book and the reader should turn to the relevant literature [1.4].
