This paper reports the result of a fireside corrosion test carried out on four low alloyed ferritic alloys at 650 °C for 1000 h. The combustion gases were derived from co‐firing cereal co‐product with a UK coal. Synthetic deposits were used to assess the influence of the deposit compositions. The samples were examined using an ESEM/EDX. To quantify the metal damage the pre‐exposure micrometre measurements were compared with the post‐exposure image analyser measurements on sample cross‐sections. The median metal damage of the alloys showed the following ranking (most to the least damage): 15Mo3>T22> T23> T91.
