PROPULSION UPDATE Bailey Offers Technical Paper On Better Combustion Control A comprehensive technical paper entitled "Oxygen Control, Carbon Monoxide Control, or Both—Which Is Best for Your Boiler?" by E.P. Smith, market manager-energy group, Bailey Controls, Burlington, Ontario, was presented at the 46th National Conference of the Institute of Power Engineers in Halifax, Nova Scotia. Copies of the paper are available free of charge. During the past 20 years, much has been published in the various trade magazines and journals on the pros and cons of excess air trim as applied to combustion boiler control systems. Some say oxygen (02) only for control is best, some say that carbon monoxide (CO) only for con- trol is best, and others say that a combination of 02 and CO is best. Which is the best for your plant? This paper attempts to sort through much of the written material that is available on the subject and help you decide on the right selection for your plant. The author concludes that the ap- plication of 0.2 or 02 + C0 excess air trim to the combustion process is a very attractive proposition for any combustion control system. Oxygen measurements are a true indication of excess air, but have no relation- ship to combustion quality and completeness of combustion. Car- bon monoxide measurements have no relationship to excess air but do provide an index of combustion quality and completeness of com- bustion. By combining the two mea- surements in one 02 + C0 system, we have the best of two worlds.
