ABSTRACT:
The invention relates to a method and a plant for cooling gases and removing dust from them. In a first step after saturation with water vapour, the gas is brought to accelerate, additional water being simultaneously added to the dust particles in the gas, whereupon the gas flow thus loaded is brought to pass over the surface of the water in a first sedimentation container (1) so that the majority of the dust content is released to the sump in the sedimentation container (1). The gas flow is thereafter subjected to final cleaning and cooling in a second step, through direct contact with water, whereupon the water utilized in this manner, possibly via a second sedimentation container (2), is wholly or partially returned to the first step.
