A novel temperature gradient laboratory-scale corrosion test method was used to study PbCl2 migration, interactions with SiO2, NaCl, Na2SO4, KCl, K2SO4, or NaCl–KCl (50:50 wt %) and corrosion of carbon steel in waste-fired boilers. Two different st

One of the biggest operational concerns in recycled wood combustion, is the risk for formation of low melting, corrosive deposits. The deposits present on low-temperature heat transfer surfaces (material temperature K 2 SO 4 is commonly regarded as n

Firing of waste-based fuels increases the risk for heavy metal-induced corrosion in the furnace walls and in other low-temperature heat transfer surfaces, such as primary superheaters. Lead-containing compounds, especially alkali lead chlorides, have
