How to extend lifetime of aged weld overlay on steam …

Ageing of weld overlayed boiler tubes Alloy 625 weld overlay of boiler pressure parts, although widespread in Waste to Energy and Biomass-fired boilers, has a limited lifetime depending on the operating conditions of the unit: its ageing starts with dealloying, followed by pitting and after some time boiler operators understand that the remaining sponge-like structure can't protect the tubes

What are stay tubes in boiler? - FindAnyAnswer.com

20/6/2020 · Hereof, how are boiler tubes supported? The stay tubes with an increased diameter act as support for the boiler.Both types are welded onto the lower and upper tube plates. The steam space is formed by the shell plate and internal cone. In the exhaust gas boiler tubes, heat from the main engine exhaust gas is transferred to the water side by convection.
