STUDY MATERIAL CONTENTS

Part- I

  • Chapter 1 : Basics of Measurement
    To understand the fundamental theory by which the boiler system works, certain basics of Physics are required to be re-visited by the participants. Fundamental concepts of work, Power, Energy and their relationship with pressure, temperature and flow are explained in this chapter. Gas Laws and concept of mole, which is essential to understand combustion mechanism is also explained. This chapter also deals with all important basics of physical measurements and their units.
  • Chapter 2 : Properties Of Steam
    Proper concept of temperature-enthalpy relation in the various part of the Boiler along with flue gas temperature profile and heat transfer process at various locations is one of the basic criteria for analytically understanding the Boiler operating conditions. This chapter deals with the concept of steam properties in details.
  • Chapter 3 : Fuels And Combustion
    Optimum conversion of chemical energy in to heat energy is one of the most important aspects of Boiler operation. In order to achieve that one should first understand the mechanism of combustion, composition of different fuel and their characteristics, how 3T conditions in the furnace affects the combustion process, etc.
    The chapter deals with all important aspects of fuel & combustion in details along with Calculation of GCV, NCV, Minimum Theoretical Air, gas composition and computation of excess air.
  • Chapter 4 : Thermodynamics & Heat Engine Cycles
    To understand the significance of the various parameters like steam temperature, pressure, condenser vacuum, etc. on the power plant performance, one needs to understand the power cycle clearly. This chapter deals with the fundamental understanding of various Steam power cycles.
