Title: Device at combustion plants for automatic feeding of fuels within the furnace of the plant

Abstract

A method is described for feeding solid fuel through a furnace of a combustion plant, comprising the steps of: positioning solid fuel on a fuel-receiving end of movable grate means, advancing the movable grate means through the furnace from the fuel-receiving end to a fuel-discharging end of the grate means, while combusting the fuel disposed thereon. The grate means is advanced through a sensing zone of the furnace disposed in the vicinity of, and upstream of, the fuel-discharging end, conducting a supply of measuring air to fuel disposed on the grate means in the sensing zone, such that the temperature of incompletely combusted fuel increases and the temperature of completely combusted fuel decreases, sensing the temperature of the fuel in the sensing zone to obtain an indication of the extent of combustion thereof, and adjusting the rate of advance of the grate means in accordance with the sensed temperature in a manner tending to achieve a complete combustion of the fuel.
