MONITORING OF FOULING OR OF LOSS OF MATERIAL OF HEAT TRANSFER TUBES IN A COMBUSTION VESSEL BY RESISTANCE MEASUREMENTS

摘要

It provides a method and system, the goods and materials for estimating that the combustion container (12) of condition heating surface exposes during depositing thereon launches burning fuel, combustion container (12) is in combustion process. Corresponding voltage, thus transient resistance power grid are detected method includes the following steps: applying electric current and forming electric network (34) in the water wall of several heat-transfer pipes of fireside surface of interested part (36). This method further comprises determining that the water of water wall or fouling of the step based at least one material loss detected deposits slag or flyash or the internal power grid (34) for generating material resistance by exterior wall.
