Summary on Grant Application Form |

The corrosion of boiler steels is a continuing problem which will be exacerbated by the increasing reliance on imported coals, the utilisation of waste materials as fuels and the increasing use of low NOx burner technology. The role of gas-phase species has been investigated widely under isothermal conditions and the mechanisms are partially understood. However, the role of deposits on the anisothermal corrosion of alloys exposed to flames and combustion gas mixtures has received little attention. It is proposed to undertake datum experiments on existing corrosion rigs with gas-phase additives to simulate the aggressive conditions found in coal-fired plant and waste incinerators. The rigs will then be modified to enable the controlled addition of metal salts to the flame which impinges on cooled alloy specimens, held at 400oC-600oC, producing a deposit. The methods involving gas-phase salt additions have been tried and shown to be successful by the applicants' team on an existing rig. The first objective is to identify the trace metal which leads to the most aggressive conditions for corroding alloys in use in coal and waste combustion systems, eg AISI310 and Inconel 625. The second objective is to identify the gas-phase conditions under which the trace metal is most detrimental. The third objective is to elucidate the mechanisms by which trace metals, sulphur and chlorine enter into the corrosion processes and to identify the conditions under which their effects can be mitigated. The fourth objective is to develop a corrosion model.
