ABSTRACT:
A shaking grate having inclined continuous tubes disposed parallel to the direction of incline and communicating with a liquid or fluid coolant circuit. The tubes are arranged on a vibrating grate carriage. The shaking grate is made free of grate bars by means of a planar tube-crosspiece-tube grate sheet construction, with the tube crosspieces having slot-shaped openings which are conically tapered in the direction of the fuel bed. The shaking grate is free of slots in the region of the fuel bed inlet as far as to the beginning of the first combustion zone of the fuel bed. The shaking grate is connected with crossbars of the vibrating grate carriage via ridge or comb plates and heat-compensating gliding elements. The shaking grate is provided with a riser for the draining liquid or fluid coolant. The riser is arranged in the charging region of the fuel bed inlet.
