Abstract:
1. A method of operation of a gasification reaction comprising: introducing solid waste material into a gasification reactor having a longitudinal axis substantially parallel to a horizontal plane; heating the reactor to pyrolyse the waste material in the reactor; agitating the waste material in the reactor using wiper blades of at least three staggered wiper blade assemblies; and cooling the gaseous product of the pyrolysis reaction in a bundle type condenser, wherein the wiper blades of the wiper blade assemblies are provided on adjoining hubs which are spaced from each other along the longitudinal axis and wherein the wiper blades of the wiper assemblies are staggered by predetermined different radial angles relative to a longitudinal axis of the reactor and are staggered relative to each other when viewed from an end of the rotatable shaft and overlapping with each other along the longitudinal axis of the reactor, and wherein each wiper has a long edge that is oriented relative to the longitudinal axis of the reactor such that an angle of orientation of each long edge to the longitudinal axis is an oblique angle of about 5° to about 50°.
