ABSTRACT:
A method for cleaning the interior wall of a tube with a slurry and a tubular lance. The method includes the steps of inserting an end of the tubular lance into the tube and pumping a fluid through the tubular lance into the tube. A slurry is pumped into the interior of the tube between the tubular lance and the interior of the tube. The slurry mixes with the fluid at the end of the tubular lance in the tube and the slurry and fluid mixture is propelled against the interior tube wall at the end of the tubular lance to clean the interior wall of the tube.
