S-TEN1 and S-TEN2 for power plants and incinerator flue gas ducts/chimneys.
Suppress sulfuric acid and hydrochloric acid dew point corrosion in areas where exhaust gas cools. Selection based on wall temperature, drain, and gas composition.
In smoke ducts and flues of thermal power plants and waste incineration facilities, SO3, HCl, and water vapor in the exhaust gas condense on the surface of steel plates, leading to sulfuric and hydrochloric acid dew point corrosion. Equipment that lowers exhaust gas temperature through heat recovery or rapid cooling, as well as bends, lower sections, and low-temperature areas during shutdown that are cooled by outside air, are prone to thinning of ordinary steel. We propose Japan Steel's acid-resistant S-TEN steel for ducts, flues, and expansions. For incineration exhaust gases where hydrochloric acid dew point corrosion is anticipated, S-TEN1 is recommended, while S-TEN2 is suitable for cases where strength and high-temperature conditions are prioritized, particularly for sulfuric acid dew point corrosion. The selection of uncoated or acid-resistant coated options, external insulation, drain removal, and dust accumulation countermeasures will be considered alongside material selection.
