Reliability Improvement Programs in Steam Distribution and Power Generation Systems
Abstract
This paper will present alternatives to costly corrective
maintenance repairs of the steam trap and condensate
return system, and the paybacks associated with instituting
a program of planned and systematic maintenance management
of that system. Energy costs can be reduced by 10%
and maintenance costs by 20%, while achieving other tangible
improvements in the reliability and efficiency of the
system.
Recent studies have shown that more than 40% of all installed
steam traps and 20% of certain types of valves need
some form of corrective action. The majority of all high
backpressure problems in condensate return systems are
due to poor design criteria in expanding or retrofitting
existing return systems. By instituting a maintenance
management program, a 95% reliability can be gained with
two to four annual maintenance cycles. The associated
operational problems can be greatly reduced.
The maintenance management concept involves: 1) centralized project management; 2) diagnostic and inspection
expertise; 3) system troubleshooting; 4) data analysis, reporting
and recommendations; 5) maintenance repairs and
follow-up; and 6)software and data base management.
Several case studies, in which the concept has been successfully
applied, will be presented.
