METHOD OF GAS REMOVAL CHANNEL PRODUCTION FOR SMOKE CHIMNEY AND SMOKE CHIMNEY Russian patent published in 2009 - IPC E04H12/28 

FIELD: construction.

SUBSTANCE: invention relates to high structures and buildings construction technologies including smoke chimneys, exhaust stacks and method of their production. The production method for chimney exhaust channel from composite material provides for the chimney producing in the form of diffuser. For this purpose, the reinforced metal mesh is installed inside the supporting channel of smoke chimney. Then, ceramic slurry is applied from the both sides of the chimney. After that, the chimney is heated to sintering temperature by gas burner flame creating glass enamel layer. Above enamel layer, the reinforced mesh with cell size from 0.5 to 3.5 mm is again laid down. Each layer is enameled until the required thickness of gas removal channel is achieved. After that, protective brick lining layer is made from the internal side of the chimney. The invention also describes gas removal channel produced according to the above-described method.

EFFECT: improved strength of gas removal channel due to chemical, abrasive and temperature stability improvement.
