A number of the components of cleaner coal energy conversion plants are subject to damage by erosive and abrasive wear particularly by coal or ash material. This is of concern to equipment suppliers who are required to provide commercial guarantees of the operating lifetimes of components, and to plant operators who need to plan maintenance schedules.
There is a requirement for reliable predictive methods for abrasive and erosive wear rates based on the characteristics of th e coals being fired. Recent developments in the application of Computer Controlled Scanning Electron Microscopy (CCSEM) for the quantitative analysis of coals, coal minerals and ash materials provides a new means of obtaining the relevant data on the coal and ash characteristics. This project is intended to make use of these advanced coal characterisation techniques within a programme of experimental work to study the erosiveness and abrasivity of coals and ashes. It is intended that theprogr amme will help:
In order to achieve the programme objectives a number of activities are planned including selecting and characterising a suite of coal and ash materials including indigenous coals from India, Southern Africa and China, in addition to British coals and coals traded on the world market using conventional techniques and advanced CCSEM analysis. The abrasion and erosion resistance of a range of materials will be studied. These will include materials employed for the manufacture of mill grinding elements, pf pipework, burner components and boiler tubes plus a number of specific erosion-resistant coatings.
Laboratory-scale testwork to quantify mill component abrasion will be carried out using the Mini-mill test facility operated by Mitsui Babcock in Renfrew. Boiler component material erosion will be tested using the erosion test rig in Renfrew. The test data will be employed in the development of methods for predicting the abrasion and erosion wear ofpower pla nt components and to inform design decisions on materials for specific duties.
