METHOD FOR REMOVING ADHERED ASH AT FLUE OF BOILER FOR REFUSE AND REFUSE DERIVED FUEL, AND FLUE OF BOILER FOR REFUSE AND REFUSE DERIVED FUEL
Document Type and Number:
Japanese Patent JP2002327903
Kind Code:
A
Abstract:
To enable proper operation to remove ash by a soot blower, to enable excellent removal of ash adhered on the surface of a heat transfer pipe, to prevent the occurrence of rupture by suppressing erosion of the heat transfer pipe, and to provide a method for removing adhered ash at the flue of a boiler for refuse and refuse derived fuel.
A method for removing adhered ash at the flue of a boiler for refuse and fuel manufactured by processing refuse is that to remove ash adhered to a heat transfer pipe 4 at a flue 20 through which exhaust gas from a fuel boiler flows.
