Popis:	The chemical techniques adopted in the pre- and post-commissioning phases at West Thurrock power station are described. Apart from the detailed account of the chemical cleaning operations, types of cleaning processes, acids and strengths, sampling arrangements, circulation rates and method of final inspection are also considered. Mention is made of the desirability of sections of the plant arriving on site in a clean sealed state. The cleaning methods bring about a rapid reduction in boiler water silica so that full load can be achieved quickly. A new technique, involving nitrogen sealing, to reduce metal pick-up during start-ups has been evolved, whilst the early control of both feed and boiler water conditions is stressed and an optimum hydrazine level determined.
