This guideline was written by the American Boiler Manufacturers Association
(ABMA) to provide boiler owners and operators, as well as consulting or
design engineers and contractors, and other interested parties with current
minimum industry guidelines to enhance the safety and reliability of the
combustion controls for industrial and utility boilers. The paper focuses on gas
and/or liquid fired boilers, and covers the design of the two predominant
combustion control schemes (Parallel Positioning and Metering) and the
applicability of each. Also, it includes minimum recommended features for the
hardware required for a combustion controls application. The paper discusses
the proper commissioning of a new combustion control application, and the
importance of maintenance, operator training and adequate operator staffing.
An example of the system design and commissioning cycle for a hypothetical
metering control system is also offered.
The specific goals of this guideline are to:
Provide concerned parties with an understanding of the requirements for
safe and reliable combustion controls so that they can be properly specified
for new and retrofit applications.
Provide concerned parties with an understanding that combustion controls
are a "system". This system incorporates the control scheme (suitable for
the requirements of the application), the actual controller, the final control
elements, the field measurement devices, the startup/commissioning and the
subsequent operation and maintenance. The safe and reliable
implementation of a combustion controls application on a multiple-burner
boiler requires thoughtful attention to all of these elements of the control
system.
Provide concerned parties with the understanding that lower boiler emissions requirements drive the need for additional combustion control precision.
Provide specific guidelines regarding the design and selection of
components for combustion control systems. | Number of Pages : | 47 |
