Course 8106      CEUs: 2.1

This course is for technicians, engineers or others who have responsibility for troubleshooting and optimization of the powerhouse area including boilers, steam headers and turbines with the goal of achieving reliable load response, efficient operations and low emissions.

Overview

This is a 3-day course that draws on the depth of experience that EnTech has accumulated during years of investigating and improving the performance of power boilers, waste fuel boilers, steam headers, PRV’s and turbines. The course focuses on a broad scope of process variability and operational stability issues that affect process reliability, energy usage and steam header stability. Issues examined include the impact of process design and control design on process stability. Topics include the affect of the water/steam system on boiler drum level dynamics from a thermodynamics perspective, improving the speed-of-response of a boiler to setpoint and load changes, stabilizing the steam header pressure and temperature controls, etc. A high fidelity dynamic simulator provides the basis for lab work.

Prerequisites

Participants should have taken Applied Modern Loop Tuning Process (9032) or Control for Engineers I (9030) or possess similar process control and instrumentation knowledge related to power house applications.
