There are boilers with quite steep grates. I have seen one that was L shaped. The fuel was dropped ‘in front of the primary air supply’ held away from the holes by the sort of vertical part of the grate, then a more horizontal part of the grate sloped down towards the combustion chamber. The point is to have a decent fire burning at the bottom of the hopper without getting the fire into the hopper itself.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Regards<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Crispin<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p></div></body></html>
