ONLINE HEAT FLUX MEASUREMENT AT MEMBRANE WALLS OF STEAM GENERATORS OF MUNICIPAL SOLID WASTE INCINERATORS

摘要

In the presented paper a measuring method is described, which makes it possible to determine the heat flux on membrane walls of combustion plants online. With the help of the online heat flux measurement a monitoring of the refractory lining and the fouling condition of the boiler is possible over entire operating periods. With the presented method important additional information for the operator is given when using difficult fuels (waste and biomass) in a steam generating process.
