This specialization provides a detailed understanding of boiler environmental, electrical, and control systems in modern thermal power plants. It begins with the fundamentals of NOx generation and reduction technologies, including primary combustion control measures, Selective Non-Catalytic Reduction (SNCR), and Selective Catalytic Reduction (SCR) systems, along with associated ammonia handling. Learners also explore Flue Gas Desulphurization (FGD) systems, including wet limestone-based FGD, major components, and limestone and gypsum handling systems. The course covers boiler electrical systems, including auxiliary power supply, HT and LT switchgears, motors, variable frequency drives, DC motors, starter panels, and earthing. Dust control systems and Electrostatic Precipitators (ESP) are explained in detail, covering ionization, ash collection, high-voltage equipment, and mechanical safety features. Instrumentation and control topics include pressure, level, flow, and temperature measurement, analysers, final control elements, HART and Foundation Fieldbus, burner control systems, boiler monitoring equipment, control logic, and Distributed Control Systems (DCS). Learners gain the skills to design, operate, and maintain reliable, efficient, and compliant boiler environmental, electrical, and control systems.

Syllabus

NOx and SOx reduction System
- This module provides a comprehensive understanding of NOx and SOx emission generation mechanisms and the technologies used for their reduction in thermal power plants. It covers NOx formation, combustion control techniques, primary emission reduction measures, Selective Non-Catalytic Reduction (SNCR), Selective Catalytic Reduction (SCR), and ammonia handling systems associated with SCR. The module also explains Flue Gas Desulphurization (FGD) systems, wet limestone-based FGD technology, major FGD components, and limestone and gypsum handling systems used for effective sulfur oxide emission control.
Electrical Systems of Boiler
- This module provides an overview of electrical systems associated with boiler operation, including auxiliary power distribution, switchgear systems, motors, drives, and electrical safety aspects. It covers high-tension (HT) and low-tension (LT) switchgears, HT and LT motors, variable frequency drives (VFDs), DC motors and starter panels, and earthing systems. The module also introduces dust control systems and electrostatic precipitators (ESP), including their working principles, high-voltage systems, major electrical components, and mechanical safety features.
Instrument and Control
- This module introduces the fundamentals of instrumentation and control systems used in boiler and thermal power plant operations. It covers measuring instruments, instrument installation concepts, analyzers, final control elements, and detailed measurement techniques for pressure, level, flow, and temperature. The module also explains instrumentation diagrams, boiler monitoring equipment, communication protocols such as HART and Foundation Fieldbus, burner control systems, boiler control logic, and Distributed Control System (DCS) architecture.
