Boiler Systems (ABC01)

The first in a three-part comprehensive INVOLVE?? multimedia-training program. This program trains participants in the operation and maintenance of boilers and their associated safety systems.

Prerequisites

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

Description

This lesson focuses on the principles of operation of boiler systems and teaches the thermodynamic principles governing steam generation and heat transfer. Basic boiler components and operations will also be covered. The lesson provides a detailed overview of how steam is generated on the water side of the boiler as well as the fundamentals of combustion and how energy is converted in the boiler??s furnace.

Objectives

Give a Detail of a typical boiler and related system. Describe the function of a boiler. Define the following terms: enthalpy, sensible heat, latent heat, latent heat of vaporization, saturation temperature, superheating, critical pressure, British Thermal Unit (BTU), and steam quality. Describe the flow of water and energy when given a general Detail of a typical steam system. Explain how each system contributes to the production of steam when given a block diagram of a typical boiler. Show the flow paths for inputs and outputs through the system when given a block diagram of a basic boiler. Identify the basic types of boilers when given Details of common features of the boilers. Describe common applications for the different boiler types. Explain the functions of the various components in a boiler when given their Details. Explain how components such as economizers and preheaters conserve heat energy and maximize the efficiency of steam production while minimizing cost when given a Detail of the principles that govern efficient steam production and optimal use Of fuel. Explain why feed water must be treated before it enters the boiler when given a Detail of 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. Identify the most common types of boiler fuels and describe their physical characteristics and heat values when given Details of the three major categories of boiler fuels. Describe the various methods for preparing the fuel for use in a boiler. Describe the principle by-products of combustion and how each is measured. Explain the importance of monitoring emissions.
