Abstract

L'invention concerne un souffleur à eau utilisé pour nettoyer des installations thermiques. Une lance à eau (6) est montée mobile (5) avec son embouchure sur ou dans une lucarne (2) et peut projeter un jet d'eau jusqu'aux zones d'une paroi atteignables depuis la lucarne (2) à travers l'installation thermique en fonctionnement et remplie de flammes et/ou de gaz de fumée. Afin de raccourcir la lance à eau (6), l'alimentation en eau (11, 10) est coudée une ou plusieurs fois en tout de plus de 70°, notamment de plus de 90° (20, 24; 39). Un volume stabilisant étendu (20, 39), notamment un volume sphéroïdal (20) situé à l'extrémité de la lance à eau (6) à l'extérieur de l'installation thermique, permet d'uniformiser le profil d'écoulement de sorte que la qualité du jet projeté par la lance à eau raccourcie ne soit pas affectée. La lance à eau raccourcie permet d'utiliser des mécanismes plus simples d'entraînement et de l'adapter à des espaces étroits.
