A lossinweight feeder is a gravimetric feeder that directly measures the material''s weight to achieve and maintain a predetermined feed rate measured in units of weight per time. The following section ( The Gravimetric Feeding Triangle ) introduces the three main challenges faced by any gravimetric feeder: material handling, weighing and control.
Generally, the gravimetric feeder receives the particulate coal in the form of a continuous stream in a fixed flow path, and delivers the coal at a controlled rate as freefalling or separately flowing particles. The rate of discharge by weight is controllable to achieve accurate control of the fuelair ratio.
