Abstract (en)

[origin: JPH01142314A] PURPOSE: To avoid the corrosion and damage caused by dust, and the erosion, damage, etc., caused by a conveyed gas, by providing a pressure management system which works to lower the pressure between two cooling stages. CONSTITUTION: The flue gas side of the combustion chamber 1 of fluidized-bed combustion equipment used under a pressure is connected to a separator 2 which separates flue dust from a flue gas. The separator 2 is provided with a gas outlet 3 and a solid outlet 3, and the solid outlet 4 is connected to a cooler 5 which cools a mixture of the flue dust and flue gas to a temperature higher than the water and acid dew point of the used flue gas. The inner tube of the cooler 5 is connected to another separator 10 which separates the flue dust from the flue gas. The solid outlet 12 of the separator 10 is connected to a pressure management system composed of a storage tank 15 and a management tank 16, and the solid outlet of the tank 16 is connected to an injector 26. The injector 26 is connected to a second cooler 28.
