Abstract

A piece of piping (1) includes an outer pipe (3) and an inner pipe (2). The outer pipe (3) consists of a stable material impermeable to liquids. The inner pipe (2) that carries waste gas is made of a sintered material, preferably plastic, metal or ceramic, and is permeable to the liquid (9) as a function of a pressure difference between the space (8) between the pipes and the inner space (20), but is essentially impermeable to liquid when the pressure is equal. The space (8) between the inner pipe (2) and the outer pipe (3) is filled with the liquid (9). If a pressure is exerted on the liquid (9) in the cavity (8), the liquid (9) permeates through the three-dimensional system of pores of the inner pipe's wall, controlled by the pressure, and wets the inside of the inner pipe's wall evenly. If the pressure is increased still further, the liquid (9) begins to drip into the inner pipe (2). The system of pipes comprises at least one piece of piping through which waste gas flows. It prevents deposits and caking on the inside walls of the pipes by wetting these with liquid (9). A drop removal facility (23) with a drop collection space (24) prevents the liquid (9) flowing backwards by dripping down.
