Carbon Deposition of 19 Fuels in an Annular Turbojet Combustor
Abstract
The effects of fuel properties and change 1n simulated e:ngine operating conditions on carbon deposition were evaluated in an aJmul.ar turboJet combustor with a diameter of l~ inches. The fuel properties examined were specific gravity, volumetric average boiling temperature, hydrocarbon type, and hydrogen-carbon weight ratio. The simulated engine operating conditions ranged f'rom sea level and 50-percent rated e:ngine speed to an altitude of 40,000 feet and rated engine speed. The fuels included hydrocarbons of the para.f'finic, olefinic, and aromatic types as well as fuel mixtures. In general, carbon deposition in the annular combustor increased with increase in boili:ng temperature a fuels of' the same hydrocarbon type. Aromatic fuels deposited more carbon than other types a fuel. of' the same boili:ng temperature. An empirical correlation a the carbon deposition, the boi11.ng temperature, and the hydrogen-carbon weight ratio of' the f'uel was obtained.
