Principles of Gasification Technology; Literature Review
Hanika, Jiří ; Jiřičný, Vladimír ; Punčochář, Miroslav ; Veselý, Václav ; Vosecký, Martin
The present review deals with gasification technologies in relation to rape grouts, which is relevant fuel at the project. Fundamentals about several gasification technologies, such as in fixed-bed, fluidized-bed and entrained flow, are discussed. Moreover, an overview of gasification units which are based on the relevant technologies is stated.

Desulphurisation of Waste Gases by Dry Additive Method
Veselý, Václav ; Čech, B.
The molar ratio Ca/S is the most frequently for comparison of efficiency and effectiveness of desulphurisation. Desulphurisation of waste gases by a dry additive method is based on the known fact that calcium oxide with sulphur dioxide and oxygen reacts to stable calcium sulphate at high temperatures (850 up to 950°C).
