Unit 1 Outline

Objectives

After studying and reviewing this unit, the student should be able to understand what is a high pressure steam boiler and the systems attaches to these boilers such as steam, water fuel and draft systems; in addition, controls, circuits and related instruments will be discussed.

- Define and describe what the ASME code is and how this code influences the different boiler classifications and the symbols used to describe flows and other relevant boiler information
- Describe water tube and fire tube boilers and how these boilers operate
- Describe what metal stress and how boilers are designed to minimize stress
- Define boiler efficiency and how a boiler efficiency can be improved
- Describe boiler construction and its different components
- Define and describe the different boiler systems including, water, feed, fuel, steam, draft, related instrumentation with controls; in addition, all these components will be studied to understand the boiler operation when all, these systems are being used

Reading Assignment

Please read about steam boilers and the different boiler systems in your textbook.

Introduction

After this week, the student will understand and apply the gained knowledge to describe the steam and/or hot water supplied by high and low pressure boilers; the steam generated can be used to power other machines to generate work which can be translated electricity, flow or other types of work. The student will recognize that a high pressure boiler is a pressurized system which produces steam from water when various types of fuel are used to heat the water which include gas, coal or electricity.

The student will also study the boiler system that allow the boiler to operate, these system deliver either fuel to the boiler, water to produce steam, instruments and controls to monitor and operate the system and a draft system to remove the products of combustion.
