Abstract
A relatively level fuel grate surface angle cooperates with multiple feed screws that press solid fuel material into and across the grate surface to continually clear off the grate. Air spaces between each pair of adjacent grate elements for under fire air each have a ninety degree deflector flange at the top of the air space extending from one grate element across the air space and up and over an adjacent grate element to deflect under fire airflow across the adjacent grate element to act as a grate sweeper. The smooth curved surface of the deflector flange between grate elements facilitates movement of the fuel and ash material and prevents from one grate element to the next and prevents clogging of the airflow space.
