Filed: 1989-04-25
Abstract: PURPOSE:To improve the combustion efficiency of coal and reduce NOx simultaneously by providing a supply port for an unburned portion that is separated from the exhaust gas right above or in a downward moving layer. CONSTITUTION:Char ascends with a flowing medium developed by a flowing air jetted out from an air chamber 46 and is reversed and rotated by an inclining partition wall 8.
