Reducing pipeline wear headaches
Growing international competition between operators of coal-fired power stations and cement plants has brought about various cost-cutting moves, one of which concerns plant maintenance. This is not to suggest that planned maintenance is now any less thorough than it was previously, but rather that it is carried out less frequently.
In the past it was customary for parts of a power station or cement works to be shut down for a brief period once a year in order to allow for inspection and servicing. Gradually this interval was extended to two and then to three years, and now operators are increasingly aiming for six years between planned maintenance shutdowns.
