Conclusion The results of RDF experimental steam gasification tests in a rotary kiln pilot plant are reported in this paper. The process performance and the gas features were evaluated by varying the feeding ratio (FR) at constant temperature (850 C) and solid residence time in the rotary kiln (7 min)

gasification in rotary kilns through the optimisation of the gas yield, development of a scale-up model and confirmation of process performance on wood feedstock. Specific objectives were: • to confirm gas yields from wood feedstock • to evaluate the impact of steam and air addition to the process

Refuse-derived fuel (RDF) steam gasification tests were performed in a rotary kiln pilot plant. The gas features were evaluated by varying the feeding ratio (FR), in the range 0.4-2.67, at a constant temperature equal to 850 C. Several experimental tests were carried out in order to evaluate the best values for the main operating variables: kiln temperature, gas and solid residence time, etc

gas quality was investigated. Therefore coal was pyrolyzed in a rotary kiln reactor before gasification in a dual fluidized bed steam gasifier. The results were compared in terms of gas quality and quantity for determination of the influence of the state of feedstock pyrolysis on the performance of steam gasification. INTRODUCTION

While SUNY's prototype will be for batch runs only, the rotary kiln gasification process is being used continuously at an industrial park in South Korea, where 100 tons per day of industrial waste from a mattress factory is converted to steam and sold to tenants of the park, Comly says

A process is disclosed for gasifying solid coal particles in a rotary kiln that produces simultaneously and continuously two distinctly different fuel gas streams from the opposite ends of a single kiln. A relatively low temperature gas is discharged from the solids inlet end of the kiln, which contains substantially all tars produced by the process
