Heat Flux Corrosion

Heat flux corrosion is generally the result of a number of unfavourable factors, such as too high heat flux, too low mass transport or too high fraction of steam in the tubes, presence of deposits on the surfaces and inadequate water quality. The influence of certain impurities in the boiler water upon corrosion can be thoroughly studied with experiments in autoclaves.

1499 experimental boiler
1 Mw boiler for corrosion experiments at KEMA (the Netherlands).

In order to be able to include the different dynamic factors in the general investigation of steam generation corrosion -heat flux, two-phase flow of the water-steam mixture and formation of deposits -N.V. KEMA has an experimental boiler installation.(Fig. 1).

See for the results paper nr: 11 and 61.
