5203 |a"This paper describes part of a continuing research programme aimed at establishing the influence of various factors on the corrosion potential of boiler flue gases. These factors include the sulphur content of coal, the cation content of coal ash and excess combustion air. From the experiments which were conducted in a pilot-scale research boiler with coals containing 6 and 7 per cent sulphur it has been established that SO₃ concentrations, acid dew-point, rate of acid build-up and neutralization of acid by fly-ash ail influence corrosion potential: the method for determining the last parameter is described in detail. The findings, so far, strongly suggest that equilibrium data relating only acid concentration and theoretical acid dew-point cannot be applied to the corrosion rate under dynamic boiler conditions where flue-gas constituents such as SO3, H2O and fly-ash are continually deposited from the gas stream. As could be expected, corrosion potential is minimal or non-existent at less than 1 per cent oxygen in the flue gas but high above 3 per cent oxygen"--Abstract, p. [1].
