Condensate and Feedwater Systems Training

553-01 Introduction to the Condensate System

When you complete this lesson, you will be able to explain the purpose and operation of all major components in the condensate system. In addition, you will be able to discuss the basic relationship between the condensate and feedwater systems.

  • Describe the general function of the condenser
  • Define condensate
  • Identify the location and purpose of the hotwell
  • Explain the basic operation of the condensate hotwell pumps
  • Describe the overall design and function of low pressure heaters
  • Discuss the purpose of the gland steam seal condenser and its relationship to the condensate system
  • Describe the purpose of a maintaining air ejector and a hogger
  • Describe the function of a deaerator

553-02 Introduction to the Feedwater System

When you complete this lesson, you will be able to describe the basic purpose and operation of the major components typically found in a feedwater system. In addition, you will be able to further explain the relationship between the condensate and feedwater systems during boiler operation.

  • Discuss the relationship between the deaerator storage tank and boiler feed pumps
  • Describe the function of a typical boiler feed pump
  • Explain the purpose and operation of the high-pressure heaters
  • Discuss the relationship between the boiler economizer and the final feedwater temperature
  • Describe the basic design and operation of a typical steam drum

553-03 Condensate and Feedwater Systems Operation

Upon completion of this lesson, you will be able to describe the basic procedures for the start-up and operation of the condensate and feedwater systems.

  • Explain the five basic steps typically used to place the condensate system in service
  • Discuss considerations taken into account when initially filling the deaerator storage tank
  • Describe two methods used to fill the feedwater system
  • List four common tasks completed when putting high and low-pressure heat exchangers in service
  • Describe basic checks power plant operators routinely make on the condensate and feedwater systems

553-04 Condensate and Feedwater System Control

When you complete this lesson, you will be able to explain steam drum level control methods and discuss their overall relationship to condensate and feedwater flow. In addition, you will be able to describe different types of level measurement used in the condensate and feedwater systems.

  • Explain how single element control responds to changes in drum level
  • Explain how three element control responds to changes in feedwater flow, steam flow, and drum level
  • Describe three types of level indication used in the condensate and feedwater systems
  • Explain the basic procedure used in the event of a tube rupture in a high pressure feedwater heater
