摘要： PROBLEM TO BE SOLVED: To enable dense phase transport for fuel without any influence on a low Nox combustion characteristic in a fine particle fuel burner having a fuel transport tube and a primary air tube coaxially disposed in the fuel transport tube.
SOLUTION: The opening discharge side of the primary air tube 9 is terminated at a distance from the opening of the fuel transport tube 7, a swirl blade 15 is provided in a suitable position, and the burner is connected to a supply line for transporting fine particle fuel in a dense phase state. The fuel is transported inside the burner in an annular fuel transport space 13 formed outside the primary air tube 9 in the radial direction, and mixed with a primary air stream discharged from the primary air tube 9 in a volute state, so that the primary air stream is condensed equally in the circumferential direction by fuel. Thus, low Nox combustion performance can be enhanced and optimized.

摘要： PROBLEM TO BE SOLVED: To provide a combined-cycle engine by a ramjet engine having a swirl generator at the combustion efficiency of about 90-99%. SOLUTION: In the combined-cycle engine having one core engine and one ram jet engine, the ram jet engine utilizes a swirl generator for rapidly and efficiently atomizing, vaporizing, and mixing a fuel. The swirl generator converts the oxidant flow into a turbulent, three-dimensional flow-field into which the fuel is introduced. In addition, the swirl generator effects a toroidal outer recirculation zone and an inner central recirculation zone, both of which are configured in a backward-flowing manner that carries heat and combustion byproducts upstream where they are employed to continuously ignite a combustible fuel and oxidizer mixture in adjacent shear layers, which accelerate flame propagation throughout the core flow-field. The swirl generator provides smooth combustion with stability and minimum total pressure losses and enables significant reduction in the L/D ratio of a combustor. Other benefits include simplicity, reliability, wide flammability limits, high combustion efficiency and high specific thrust performance. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an afterburner apparatus that is relatively short and light, and has better fuel rate. SOLUTION: The afterburner apparatus utilizes a swirl generator for rapidly and efficiently atomizing, vaporizing, and mixing fuel into an oxidant. The swirl generator converts oxidant flow into turbulent, three-dimensional flow field into which the fuel is introduced. The swirl generator effects a toroidal outer recirculation zone and a central recirculation zone, which is positioned within the outer recirculation zone. These recirculation zones are configured in a backward-flowing manner that carries heat and combustion byproducts upstream where they are employed to continuously ignite a combustible fuel/oxidizer mixture in adjacent shear layers. The recirculation zones accelerate flame propagation to allow afterburning to be completed in a relatively short length. Inherent with this swirl afterburner concept are design compactness, light weight, lower cost, smooth and efficient combustion, high thrust output, wide flammability limits, continuous operation at stoichiometric fuel/oxidizer mixture ratios, no combustion instabilities, and relatively low pressure losses.
