METHOD AND DEVICE FOR PROTECTING HEAT EXCHANGER PIPES AND A CERAMIC COMPONENT

摘要

The method involves surrounding a heat exchanging tube (10) by a ceramic component (6), in which flue gas flowed from two opposing sides. The gas is supplied between the heat exchanging tube and the ceramic component. The gas is supplied at the hottest point between the heat exchanging tube and the ceramic component. The gas is supplied by a gas pipe (13) extending in the ceramic component. Independent claims are included for the following: (1) a device for the protection of heat exchanging tubes in boiler systems using a ceramic component; and (2) a ceramic component.
