Chemical cleaning can play an important role in boiler maintenance. Proper chemical cleaning removes deposits from the inside of boiler tubes which improves the boiler heat rate, reduces tube failures and improves the stability of boiler chemistry. However, chemical cleaning is expensive. Vendor costs alone may total $50,000 to $150,000

The most important key performance indicator is the molar ratio H 2 S/SO 2 exiting the waste heat boiler. It should be as close as possible to the value of 2 in order to get the maximum conversion in sulfur ( Karan et al., 1994; Monnery et al., 1993; Nasato et al., 1994 ).

The production of high pressure steam requires an exit temperature from the waste heat boiler WHB of about 600 F. or higher. The exit gas from waste heat boiler WHB is passed via line 16 to low pressure boiler LPB which further cools the gas from ≧600° F. to a pressure suitable as low pressure steam (typically between 30 and 150 psig shown by line 18 ).
