The grate element has an outwardly curved front wall (22) having a nominal wall thickness varying by less than ±35%, and a lower inwardly curved wall portion extending from the top wall of the grate element to the front end, and the outwardly curved front wall forming the front tip edge (23) of the front end at the junction of the outwardly curved front wall and the lower inwardly curved wall portion.

An apparatus for combustion of solid fuel material can be configured to utilize one or more oxidant injectors positioned to inject a high oxygen content oxidant into at least one zone of a combustion chamber below a grate on which the solid fuel material is positioned to facilitate improved combustion of the material. In some embodiments, the injected oxidant can have an oxygen content of at least 80 mole percent, which can supplement other oxidant passed into the combustion chamber that has a lower oxygen concentration. The oxidant injector(s) can be selectively utilized to facilitate improved combustion startup and to facilitate combustion of low quality or high moisture solid fuel material. In some embodiments, the oxidant injector(s) can be positioned below one or more burners and be positioned upstream, downstream and / or coincident to the burner(s) and also below the grate and the burner(s) in the combustion chamber.

The present application relates to a grate line bordering element (11) for a combustion grate for burning waste, comprising a channel element (15) and a channel covering (17) for covering the channel element (15) comprising at least one covering element (21, 23) and one termination element (25) with a locking device; wherein the termination element (25) has a support surface which points away from the channel element (15) and a first engaging element which is oriented towards the covering element (21, 23); the covering element (21, 23) has a support surface which points away from the channel element (15), a retaining element which is oriented towards the channel element (15), a second engaging element which is oriented towards the termination element (25) and is configured to receive the first engaging element, and a cut-out which is oriented towards the termination element (25) for receiving the locking device of the closure element (25); and wherein the locking device is configured in such a way that it locks the termination element (25) releasably in the channel element (15).

This utility model patent discloses a waste incinerator, including a waste feed hopper, a combustion chamber, and a slag pit. The combustion chamber is equipped with multiple fixed grates and sliding grate assemblies. The fixed grates are stepped, and the sliding grate assembly includes a base connecting two adjacent fixed grates, and a sliding grate that moves back and forth on the base via a sliding push rod. This loosens and turns the waste, pushing it to the next level of fixed grate for efficient waste incineration. This utility model patent has advantages such as simple structure, low cost, large waste processing capacity, and high combustion efficiency.

A cooled grate block as part of a grate for a system for thermally treating waste, including: a block body in the form of a cast part having an outer supporting face for the waste to be treated; a flat cavity situated directly below the supporting face, for receiving a cooling fluid; a fluid feed line and a fluid discharge line, which are connected to the cavity; at least one deflection element, which is arranged in the cavity to direct a cooling fluid within the cavity from the fluid feed line to the fluid discharge line; and a valve element situated in the end region of the cavity, for distributing the cooling fluid fed into the cavity through the fluid feed line.
