Investigation of the corrosion behaviour of 13CrMo4–5 …

15/3/2015 · The investigated boiler steel 13CrMo4–5 is commonly used as steel for superheater tube bundles in biomass fired boilers. Forest wood chips and quality sorted waste wood (A1–A2 according to German standards) as relevant fuels have been selected to investigate the influence on the deposit formation and corrosion behaviour.

Superheater corrosion in biomass and waste fired boilers …

Biomass and waste fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work high temperature corrosion of superheater alloys, and methods to mitigate the problem, have been investigated by laboratory studies and controlled field exposures in commercial boilers.

Corrosion Problems in Incinerators and Biomass-Fuel …

Incinerators are widely used to burn the municipal waste, biowaste, wood, straw, and biomedical waste. Combustion of these types of waste results in generation of chlorides of sodium and potassium which may attack the metallic part of the incinerator. In biofuel-fired boilers, similar type of highly corrosive environment is present. Attempt has been made to review the corrosion problems and

Reducing superheater corrosion in wood‐fired boilers - …

3/2/2006 · One of the major drawbacks to the combustion of biomass in power station boilers is the increase in the fouling and corrosion of superheaters. Experience shows that conventional superheater steels last no more than 20 000 h or four operating years before they must be replaced, if wood-based fuel is used and the steam temperature is higher than 480°C.

Boiler Corrosion Prevention for Waste & Biomass Boilers

We provide corrosion-resistant metal alloy protection for Waste incinerators, biomass- and Waste-to-Energy Boilers. Typically designed for medium or large installations, these boilers produce steam by burning biomass, recycled biomass, or pre-treated industrial or urban waste. Fuel flexibility offers related cost reduction but results in boiler

Thermal Spray Coatings for High-Temperature Corrosion …

There are over 1000 biomass boilers and about 500 plants using waste as fuel in Europe, and the numbers are increasing. Many of them encounter serious problems with high-temperature corrosion due to detrimental elements such as chlorides, alkali metals, and heavy metals. By HVOF spraying, it is possible to produce very dense and well-adhered coatings, which can be applied for corrosion
