Abstract
In an automatic boiler having an internal hopper, a regulator plate 12 controls the flow under gravity of fuel to the firebed. For small particled fuel in particular the plate is provided with a torque 23 which causes a central thinning of the firebed. Thus, a centrally disposed shallow firebed is formed so that primary air can rapidly break through at this point to burn off volatile gases as they are distilled and cause ignition over the whole firebed.
