Title: Configuring the EPRI plant monitoring workstation for boiler section cleanliness at Texas Utilities`s Martin Lake Plant

Abstract

T.U. Electric`s Martin Lake plant has a history of boiler slagging which is characteristic of the Texas lignite used as fuel. Using the capabilities of EPRI`s Plant Monitoring Workstation (PMW) and enhanced performance monitoring instrumentation, Martin Lake has developed an on-line boiler cleanliness model that can be used to manage sootblowing. Testing of the model has been very positive, showing good correlation between blowers operated and cleanliness obtained. potential applications of this model are for (1) testing the effectiveness of revised combustion strategies and (2) development of an automatic sootblowing system. These two areas could result in heat rate improvements. This paper discusses how the PMW models were configured to represent Martin Lake`s boilers and the results of on-line tests. Critical to this technique is the calculation of boiler gas flow. A somewhat unique feature of Martin Lake`s model is the calculation of boiler gas flow based on the induction draft (ID) fan horsepower. Most boiler gas flow calculations are based on stack gas flow which would have been inaccurate because of the wet scrubbers and stack gas reheat on this unit. Using the ID fan horsepower to derive boiler gas flow has application in boiler efficiency calculations as well.
