| COURSE OUTLINE | LEARNING OBJECTIVES | COURSE FEE |
The Steam Surface Condenser and Closed Feedwater Heater Seminar is conducted in a slide assisted lecture/discussion format. The seminar instructor is a highly experienced power plant heat exchanger engineer and consultant.
This seminar provides the participants with the relevant information that is required to identify, evaluate, and correct condenser and feedwater heater performance, operation and maintenance problems.
Upon completion of this course, participants will understand the principles of operation of a steam surface condenser and will be able to develop strategies for performance improvement and increased availability. The participants will also learn about steam surface condenser design; aqueous corrosion; heat exchanger fouling; condenser performance monitoring and testing; retubing; and non-destructive examination of heat exchanger tubes.
The Course Director is Mr. Robert J. Bell, President of Heat Exchanger Systems, Inc., a consulting engineering and non-destructive testing firm in Boston, Massachusetts. He specializes in the analysis and specification of steam surface condensers and associated systems. Mr. Bell's experience includes performance testing, performance monitoring, corrosion failure analysis, vendor surveillance, materials selection, consultation on operation and maintenance, condenser retubing and troubleshooting.
This course is intended for those plant engineers, results performance engineers, and plant operation/maintenance supervisors. Also, support staff that are concerned with specification, operation, maintenance and repair of steam surface condensers and closed feed water heaters. The program is of special value to personnel who are required to evaluate the condition and operation of existing equipment, make "repair or replace" decisions, and resolve operating problems.
Advantages to your company include:
The participants will substantially increase their ability to evaluate the condition and operation of existing steam surface condensers and closed feedwater heaters.
Increased technical background to make repair or replace decisions.
Interaction of your plant engineers, results/performance engineers, and plant operation/maintenance supervisors.
Customization of this course for your plant.
Potential increase in heat exchanger components life.
STEAM SURFACE CONDENSER & CLOSED FEEDWATER HEATER OPERATION, MAINTENANCE AND PERFORMANCE
SESSION 1 - Heat Transfer Principles For Steam Surface Condensers The seminar builds upon simple conduction through a solid plate of a homogeneous material and adds the complexity of evaluating heat transfer through a series of plates of different materials to demonstrate the analysis of multiple heat transfer resistances. In addition, circular geometry is discussed. This leads to the analysis of heat transfer in a heat exchanger tube. Temperature duty diagrams for the condensing phase are reviewed. The five resistances to heat transfer are identified and related to steam surface condenser rating methods.
SESSION 2 - Steam Surface Condenser Functions and Theory of Operation The heat transfer principles of single tube condensing are applied to large tube bundles. Bundle design principles such as radial flow are discussed. The theory of tube bundle operation is reviewed. Effects of excessive air in-leakage, bundle deaeration performance, air removal equipment performance, and hotwell deaeration are discussed. Several types of steam surface condensers are reviewed.
SESSION 3 - Fouling in a Steam Surface Condenser Forms of macrofouling and microfouling in various environments are discussed. Control methods and condenser cleaning technologies are identified.
SESSION 4 - Feedwater Heater Functions and Theory of Operation/Application Temperature duty diagrams for counter flow and the condensing phase are reviewed. The functions of a feedwater heater are discussed. The types of feedwater heaters and the types of feedwater heater zones are identified and advantages and disadvantages of each are discussed.
SESSION 5 - Feedwater Heater Failure Causes An overview of the most frequent failure causes such as impingement erosion are presented. The relationship between feedwater design, feedwater heater normal and abnormal modes of operation, alternate tube materials and other component failures such as impingement plates are discussed.
SESSION 6 - Feedwater Heater Operation and Maintenance The maintenance of level, the effects of heaters out of service, leak detection, record keeping, visual examination, lay up, selected repair technologies including tube plugging are discussed.
SESSION 7 - Condenser Failure Causes An overview of the most frequent tube problems both on the steamside (impingement attack, flow induced vibration, condensate corrosion and stress corrosion cracking) and on the waterside (such as galvanic corrosion, dealloying, pitting, and sulfide attack) are presented. Proper design, operation and maintenance methods are also identified.
SESSION 8 - Condenser Instrumentation Circulating waterside and steamside monitoring parameters and the instrumentation for determining these parameters on-line and in testing are identified. Performance testing is discussed including the need for testing, available codes, and alternate techniques.
SESSION 9 - Condenser Operation & Maintenance Operation and maintenance practices for the steam surface condensers are identified. These include performance monitoring and economic cleaning schedules. The methods of equipment condition monitoring and assessment are also discussed. These include record keeping and visual examination techniques. Tube plugging and life extension technologies are also identified.
SESSION 10 - Non-Destructive and Destructive Examination Techniques Principles of various techniques, including eddy current testing and ultrasonic testing will be discussed and their application to condensers and feedwater heaters will be identified.
SESSION 11 - Condenser Retubing and Rebundling The available methods and tooling will be identified and the advantages and limitations of each will be discussed.
