Title	Scaling Law for Emission of Pollutant from Combustion Furnace
Creator	Sadakata, M.; Hirose, Y.
Publisher	Digitized by J. Willard Marriott Library, University of Utah
Date	1991
Spatial Coverage	presented at Honolulu, Hawaii
Abstract	For the development of a new combustion system, a reliable scaling law is required. The scaling law means the method of scale up which can keep the combustion characteristics in the scale up from a small model furnace to a practical furnace or the method of scale down which can realize the same phenomena which is occurred in the practical furnace by using the small model furnace. The study of scal ing law attracted many researchers concern in early time. Colloquium on scaling law was held at Ninth Symposium on Combustion at Cornell University. In this Symposium, conventional scaling law and modeling study were reviewed and an idea of partial model ing and the method of isothermal mode or effective scaling law for gas turbine combustion were introduced. However, the concerning of the combustion researchers was shifted to the basic research field afterwards and the study of the scaling law was not advanced significantly except a study of fire. As the result, the scaling of the practical combustor has been carried out by try and error method.

Then, above scaling theory was applied to the practical burner and consequently " one-third power law " was derived. The adequacy of this scaling law was verified by the data of NOx emission from three different type practical burners. 7.
