Abstract
PURPOSE:To effectively carry out cooling of a gas at the outlet of a coal gasifying furnace, reduce adhesion degree of ash or char and facilitate flowing down of once adhered slag, by providing a panel-shaped water-cooled wall for exclusive use in cooling the gas at the outlet part of a reductor. CONSTITUTION:A panel-shaped water-cooled wall 5 for exclusive use in cooling a gas is provided at the outlet part of a reductor 20 to effectively carry out cooling of a gas at the outlet of a coal gasifying furnace. Furthermore, the outlet gas is effectively reduced to a temperature for preventing the outlet gas from slacking without changing gasifying reaction condition, such as structure of the water-cooled wall 5 of the gasifying furnace or extension of the part of the reductor 20, in carrying out temperature control of the outlet gas in using many kinds of coal even if the gasifying furnace temperature within a wide range. Since the water-cooled wall 5 is the panel-shaped multilayered structure, adhesion degree of ash, char, etc., is reduced as in a tube group 26 of a normal heat exchanger 21 and the flowing down of once adhered slag is facilitated.
