This course is designed to aid personnel assigned the task of maintaining optimum NOx/CO emissions from a coal fired steam generator.   The emphasis will be on combustion system optimization of a tangential firing system and include the following systems and equipment:

• Fuel Firing Equipment / Tangential Firing Systems
• Control of Primary and Secondary Air
• Optimization of NOx/CO Emissions from the Firing System
• GE RSFC™ Wall Fired Burner

Duration

2 Days

Target Audience

• Supervisors
• Operations
• Instrumentation & Controls

Prerequisites

• Instruction is given in English; therefore, a reasonable ability to read and understand spoken English is required
• Although not required, attendance in the Boiler Design and Testing Fundamentals course is recommended.

Class Size

Maximum number of students:  18

Learning Objectives

This course will provide basic knowledge on the following:

• Requirements for optimum combustion of pulverized coal in a tangential fired steam generator
• Major components of GE’s tangential firing system
• How NOx is generated in the furnace and how it can be controlled
• Major components of GE’s LNCFS™ (Low NOx Concentric Firing System)
• Key operating variables that affect NOx
• Possible operating and/or mechanical conditions that could contribute to high NOx on GE’s LNCFS™ firing system
• Major Components of a GE RSFC™ Wall
• Fired Burner
• Possible operating and/or mechanical conditions that could contribute to high NOx on GE's RSFC™ Wall Fired Burner
