What is the correct relation between the air/fuel ratio and low-temperature corrosion?

Low-temperature corrosion can occur in both oil fired and exhaust/waste heat recovery boilers. Considering a fuel with same sulfur content, the air/fuel number (lamda), in a combustion process also indicates a relation to what temperature sulphuric acid condensates. High air/fuel ratio rises the condensation temperature and thereby reducing the safe limits between normal operation and condensation temperature.
