B104 South: Steam, Draft, & Control Systems

  • Ramada Inn - Bordentown 1083 Route 206 N Bordentown, NJ USA (map)


B104 provides an understanding of boiler steam, draft, and control systems through a study of the various fittings and systems installed with the equipment. This course is essential for an operator’s understanding of the different types of steam produced in boiler systems and the valves and fittings used to control it. We will discuss the relationship between pressure and boiling point, saturated steam vs superheated steam. Using dynamic presentation builds, we will actually build a basic boiler room steam system in order to easily illustrate how the process, or steam cycle, really works. As operators, we must manage the various problems that could occur in the steam cycle, including carryover and maintaining dry steam. We cover the draft system and all of it’s functions in the boiler’s process, including combustion air, combustion gas, and emissions control.

When it comes to control systems, we start by teaching how a fundamental process control loop works. From there we can apply these various control loops to the boiler’s programmer or “brains”. We also break down the differences between BMS (Burner Management System) and BPCS (Boiler Process Control Systems).
