Document Type and Number:
Japanese Patent JPS6256794
Kind Code:
A
Abstract:
Each heat-exchanger surface is comprised of parallel coolant-carrying tubes and at least one soot-blowing tube which can be supplied with a soot-blowing medium and which has at least one nozzle for the egress of the soot-blowing medium. A protective tube connected to the heat-exchanger surface is disposed before and parallel to the soot-blowing tube on the heat-receiving side of the wall and is flowed through by the same coolant as flows through the heat-exchanger surface. The nozzle extend between the protective tube and the wall. The soot-blowing tube has satisfactory heating protection and the coolant in the protective tube has the same exit temperature as the other tubes of the heat-exchanger heating surface.
