High-temperature corrosion problems in steam boilers

Abstract. There are essentially three distinct high temperature corrosion problems in fossil fuel fired steam boilers. These are: (1) corrosion of the superheaters and reheaters due to the deposition of fuel impurities, principally alkali metal sulfates in the case of coal-fired boilers and vanadium pentoxide in the case of oil-fired units.

Prediction of high-temperature rapid combustion behaviour

Feb 01, 2016 · Biomass energy is becoming a promising option to reduce CO 2 emissions, due to its renewability and carbon neutrality. Normally, biomass has high moisture and volatile contents, and thus its combustion behaviour is significantly different from that of coal, resulting in difficulties for large percentage biomass co-firing in coal-fired boilers.

Best practice guidance for biomass boiler operation

When fossil fuels, such as oil and coal, are used for combustion, the corrosion rate experienced by superheaters is considerably low. The steam temperature can therefore remain high e.g. 650 °C, while for biomass- and waste-fired powerplants, the range of temperature is kept between 350 and 550 °C [26].
