Dewatering Problem Solved at Mass Burn Incinerators
Mass-burn incinerators burn unprocessed garbage and solid waste to produce heat to make steam for steam turbines that produce electricity. This often times can become a challenging task because of dewatering, lime build up and sometimes shutdowns. Different conveying processes can be used, but horizontal motion conveying has proven to be the most successful at a large energy producer plants. Belt conveyors cannot be used because of the surge-loading. Hot-quenched ash with lime added to control the ph, will stick to the pan of the natural frequency conveyors, causing them to stall-out under load. The natural frequency conveyor and the vertical pitching motion partially de-waters the ash causing it to stick to the pan. On the other hand, the gentle horizontal, slow-advance, qu
