ABSTRACT:
A grate bar support for use in combustion furnaces, particularly rubbish incinerators, has a hollow-box shaped member having a trapezoidal cross-section along a longitudinal direction and trapezoidal cross-section along a direction transverse to the longitudinal direction, a front and a rear end and a nozzle shaped air outlet opening located at the front end of the hollow box shaped member. A grate is formed by a plurality of overlapping alternately stationary and movable rows of grate bars having a stroke which corresponds to the distance two adjacent rows of grate bars are offset with respect to each other. Preferably, the grate bar supports are arcuately shaped so as to provide a tight grate surface in both cold and hot operating conditions.
