GLASS-BLOCK AIR HEATER Russian patent published in 2005 - IPC

FIELD: heat power engineering.

SUBSTANCE: according to proposed invention heat of smoke gases from boiler units and industrial furnaces is used for heating air delivered for burning. Air heater contains pack of glass blocks of heat-exchange members made of heat-resistant low-alkali reinforced or non-reinforced glass secured between two tube plates through seals by bolts and placed in housing with cover. Said glass heat-exchange members are essentially multichannel or single-channel glass blocks with air channels having rough surface of glass and, through wall, gas channels with smooth surface of glass, all arranged lengthwise each block. Glass blocks are arranged in multiple-row bond system with formation of through like channels lengthwise the pack interconnected in length through flexible seals with gaskets between rows, side surfaces of blocks and housing.
