Patent WO-02052193-A1 (WO)
Title: Generateur d'eau chaude et de vapeur
Inventor: GUO DESHENG
IPC: F22B3/06
Filed: 2000-12-25
Abstract: L'invention porte sur un générateur d'eau chaude et de vapeur comprenant un soubassement sur lequel sont placés une centrale, un dispositif d'emplacement, une lanterne, une roue de rotation et des plaques d'étanchéité; la roue de rotation est placée dans la lanterne dont les deux pièces de détente sont rendues étanches par des plaques d'étanchéité, la lanterne étant fixée sur le dispositif d'emplacement à l'aide d'un raccord. Un trou central est pratiqué dans le centre de la roue de rotation et des trous poinçonnés sont en communication avec le trou central de la roue de rotation. Le diamètre des trous poinçonnés augmente vers l'extérieur à partir de l'extrémité de base en communication avec le trou central. Grâce à cet agencement, l'eau s'écoulant dans la lanterne peut être éjectée vers l'extérieur à travers les trous poinçonnés par la force centrifuge de la rotation effectuée par la roue de rotation. Les molécules d'eau sont soumises à une forte collision et à un frottement important lorsque l'eau traverse les trous poinçonnés de manière que l'eau soit réchauffée afin d'obtenir de l'eau chaude et de la vapeur.

Patent DE-2003039-A1 (DE)
Title: Heating tower for blast furnace gas
Inventor: G B KUTNER MARK
IPC: C21B9/00
Filed: 1970-01-23
Abstract: The heating tower for blast furnace gases comprises a vertical shaft contained in a metallic housing and is subdivided vertically into two chambers, one being a combustion chamber and the other a refractory chequer work containing heating chamber. The shaft is topped by a cupola, the space below which serves as a connection between the two chambers. The cupola is supported by a separate independent support wall in the vertical shaft of the tower inserted between the inner brickwork and the outer metallic housing. Separate support brackets are the preferred way of supporting this wall. The arrangement successfully prevents the transmission of the various thermal stresses set up in the tower to the cupola thus saving it from these and consequent cracking and failure.
