Abstract
A method and apparatus for separating dust from hot process gases. The process gases are passed via a gas inlet duct through a dust separator, in which dust is separated from the process gases, part of the separated dust being conducted to a device for agglomeration of the dust. Subsequently, part of the separated dust is recirculated by being introduced into the process gases in the gas inlet duct. Liquid is added to the dust in the agglomeration device in such an amount that the relative humidity in the process gases cleaned in the dust separator is higher than 30%, preferably 40-60%.
