FIRE GRATE TO FURNACE PLANT FOR COMBUSTION OF SOLID FUEL Russian patent published in 2010 - IPC F23H1/00 

FIELD: power engineering.

SUBSTANCE: fire grate to furnace plant for combustion of solid fuel, which is arranged in the form of round plate having through holes or bar spacings for passage of air into chamber and installed on supports of furnace chamber. Through holes or bar spacings are arranged in rows concentrically oriented relative to central zone of plate, between which there are cooling ribs provided on back surface of plate. Cross sections of bas spacings are radially oriented relative to central zone of plate, and generatrices of their surfaces or axes of symmetry of plate through holes are unidirectionally inclined to working surface of plate to make sharp angles, tops of which are oriented in counterclockwise direction. Value of sharp angle between generatrices of bar spacing surfaces or axes of symmetry and working surface of plate makes 30-60°. Plate is formed by sector plates, radially oriented surfaces of which have grooves and ledges for contact interaction of adjacent sector plates to each other.

EFFECT: intensifies process of solid fuel combustion with various fractional composition of particles.
