Abstract

Disclosed is a method for removing solids deposited especially on a pipe bottom of a vertical waste heat boiler with the help of the cooling water that is used. The aim of the invention is to be able to generate a predetermined solid-removing flow above the pipe bottom in order to simplify the design and create an optimum cleaning effect. Said aim is achieved by a plurality of cooling bores which are arranged at an angle to the vertical line, are introduced into the pipe bottom, and generate a positive flow of the cooling water in the region of the pipe bottom surface.
