ABSTRACT:
A refuse fuel burning boiler system incorporating a unique tuyere construction wherein the tuyere plates associated with the conveyor-like stoker grate are hingedly mounted to permit the passage of any hard deposits of metal or glass contaminates which form upon the grate during incineration of the refuse fuel. The tuyere plates and support structure are designed for relatively easy retrofit into an existing conventionally designed refuse burning boiler or be incorporated into a new boiler construction. Vertical pivoting of the tuyere plates is limited by hold-down members installed between adjacent plates. These members further function to fix the lateral position of each plate and form the top of an enclosure over the recess in the support wall in which the plates are pivotally mounted.
