Title (EN) WATER-COOLED GRATE
(FR) GRILLE REFROIDIE A L'EAU
Abstract:
(EN) The present invention relates to a water-cooled grate, which can be cooled while avoiding high and low temperature corrosions. The water-cooled grate comprises: at least one cooling pipe for guiding flow of cooling water; a grate body for placing waste matters to be burned, said grate body being formed with a pipe-receiving portion for receiving the cooling pipe; and a heat transfer controlling member fixed to the pipe-receiving portion for increasing and decreasing heat transfer between the grate body and the cooling pipe by varying thermal resistance to the cooling pipe through thermal deformation according to temperature change of the grate body.
(FR) L'invention porte sur une grille refroidie à l'eau, que l'on peut refroidir en évitant les corrosions à haute et à basse température. La grille refroidie à l'eau de l'invention comprend: au moins une conduite de refroidissement qui guide un flux d'eau de refroidissement; un corps de grille sur lequel on peut placer les déchets à brûler, lequel corps de grille comprend une partie réceptrice de conduite destinée à recevoir la conduite de refroidissement; et un organe de régulation de transfert thermique fixé sur la partie réceptrice de conduite, qui est destiné à augmenter ou diminuer le transfert thermique entre le corps de grille et la conduite de refroidissement en faisant varier la résistance thermique à la conduite de refroidissement via une déformation thermique liée au changement de température du corps de grille.
