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).
