Troubleshooting Boiler Controls (ABC03)

The third in a three-part comprehensive INVOLVE?? multimedia-training program. This program teaches how to troubleshoot various boiler control systems.

Prerequisites

This lesson is designed for participants familiar with process operations and industrial process control.

Description

This lesson teaches how to troubleshoot various boiler control systems. Problems that might be encountered in each phase of boiler operation from startup to shut down will be discussed. The lesson also covers permissive, interlocks, shutdown systems and their associated logic.

Objectives

Identify the conditions that must be met prior to initiating boiler startup. Explain the purpose of each step in a typical operation. Troubleshoot cause of startup failure. Troubleshoot the source of the problem. Identify the safety concerns with improper furnace pressure and methods for detecting and correcting furnace pressure problems. Troubleshoot the problem if given a problem with furnace pressure. Troubleshoot the problem if given a problem with drum level. Identify the safety concerns with high steam pressure and methods for relieving pressure. Explain the purpose of each step in a typical shutdown operation, given a sequential Detail of the tasks involved in shutting down a boiler. Identify parameters that could cause an emergency shutdown. Describe methods of troubleshooting the cause of a shutdown. The effects of corrosion and scale on boiler components. Describe the principles of combustion in a boiler furnace. Explain the functions of the components in the fuel and air systems.
