The present disclosure is directed to a firebox basket for a barbeque grill or smoker. In one form, the present disclosure provides a grill comprising an ash depository, a firebox basket positioned in the grill above the ash depository; and a cooking rack positioned above the firebox basket. The firebox basket comprises: a support basket defining an internal area, the support basket comprising: a plurality of concentrically stacked rungs that define a side wall of the firebox basket; and a grate positioned at a bottom of the plurality of concentrically stacked rungs; and a plurality of ceramic pieces disposed within the support basket. The support basket is configured to support the plurality of ceramic pieces around the internal area of the support basket.

A grate bar configured to include a reinforcement structure of sheet metal and structured to be manufacture at a reduced cost while exhibiting reduced wear and enhanced resistivity to hear and corrosives. A metal-ceramic compound grate (for example—an incinerator grate) utilizing such a grate bar. An incinerator and a cooling grate including such grate bar.

Embodiments of the invention relate to a grate bar front section and a matching grate bar rear section and to a grate bar including the grate bar front section and/or the grate bar rear section configured such that, by releasably connecting the grate bar front section to the grate bar rear section, manufacture and maintenance costs are reduced.

The present invention relates to burners and boiler structures of heating systems which work with solid fuel or which work especially with wood pellets, olive stones and other similar propellants. The burner has a C-shaped grate structure comprising a grate mount (4.2) for opening and closing an ash discharging mouth, and the top grate made up by the following components: Grate arms (4.1.2) that can move at a horizontal angle over connecting grate shafts (4.1.3) independent from each other; grate shims (4.1.4) located on the grate shafts (4.1.3) and between the grate arms (4.1.2); a shank (4.1.5) connecting the grate arms (4.1.2) to a grate frame (4.1.1), and the top grate to the grate mount (4.2), thus enabling the top grate to move in an upwards or downwards motion limited by supports (4.1.7, 4.1.8). Furthermore, the burner comprises uneven rails on which the top grate moves guided by guide pins (4.1.6).
