Boiler Control Systems Oxygen Trim Systems Manual.

摘要

The Oxygen Trim Systems Manual is intended to serve as a guide for boiler operating personnel in understanding the concepts and principles which govern combustion air trim systems and their application to industrial boiler combustion control for the purpose of increasing the boiler efficiency. The Oxygen Trim Systems Manual also serves to familiarize the boiler operating personnel with the various trim systems that are commercially available, using different constituents of the flue gas as a control parameter. The manual is generally confined to oil and gas-fired heating boilers in the 60 million BTU per hour capacity range, but many of the concepts and principles discussed are applicable to boilers of any size. Combustion air trim systems employing carbon dioxide, oxygen, and carbon monoxide as a control parameter, singly or in combination, are covered. Smoke prevention and control is also discussed. Section 2.0 is devoted to terminology and definitions of technical and non-technical terms peculiar to combustion control, with which the user might not be familiar. This was done so that the manual be self-contained to the extent practicable.
