Abstract

The objective of this study is to investigate reduction method of startup period that is a kind of combustion instability of catalytic combustors with various ambient humidity and temperatures. Ignition did not occur in a high humidity environment with a relative humidity of 80% or more, and a longer preheating time was required in 15°C environmental condition. To solve the problem, we devised a method by adding a small amount of ethanol during the preheating period at specified catalyst temperature conditions. It was possible to stably ignite the catalyst even in a high humidity environment. The ignition time was able to shorten the preheating time by up to 55% regardless of the influence of ambient temperature and humidity. The optimum ethanol supply condition is to inject a total amount of 20 cc at a injection rate of about 0.8 cc/s when the range of catalyst temperature is 200 to 220°C.
