Abstract
A material feeding apparatus and method for providing a controlled feed of material. In particular, there is described a material feeding control apparatus and method comprising a feed rate measurement device capable of providing an online mass and/or volume flow measurement of material and a material sensing device capable of providing an online content (e.g. composition) measurement of the material. The material being fed may, for example, be any suitable bulk material including fuel for a combustion chamber (e.g. a furnace), mined materials such as iron ore and food in a food feeding system. A particular example of the present invention is the provision of a fuel feeding apparatus capable of providing substantially stable combustion in a combustion chamber (e.g. a furnace) which may be incorporated into a cement production line.
