Afterburning method for combustion ash and afterburner

Abstract: PROBLEM TO BE SOLVED: To provide an afterburning method for combustion ash and an afterburner device for efficiently processing the ash containing uncombusted portion in a fluidized bed combustion furnace. SOLUTION: The ash containing uncombusted portion produced through combustion in the fluidized bed combustion furnace A and gathered by a dust collecting machine 12 is supplied to a fine powder burning combustion furnace B, and the combustible component of the ash is burnt in a different burning environment. The fine powder burning combustion furnace B is furnished with a supplying means C for the ash containing uncombusted portion from the fluidized bed combustion furnace A. COPYRIGHT: (C)2004,JPO

Improvement of the performance of a turbo-ramjet engine for UAV and missile applications

Abstract: : An existing turbo-ramjet engine was modified in order to increase the produced thrust and sustain combustion at increased freejet Mach numbers. The engine's afterburner fuel system was redesigned to improve the vaporization and atomization of the fuel. The engine performed satisfactorily at speeds up to Mach 0.3, producing 100% more thrust over the baseline turbojet. The data acquisition system of the turbo-ramjet engine's performance measurement in a freejet facility was also updated. Various Computational Fluid Dynamics models of the flow through the turbo-ramjet engine were developed to visualize the flow and to predict the engine performance at different Mach numbers.

Multi-reformable fuel delivery systems and methods for fuel cells

Abstract: The present teachings provide multi-reformable fuel delivery systems and methods that can deliver, without the use of a liquid pump, any hydrocarbon fuel, i.e., a liquid or gaseous reformable fuel, for example, to at least one of a reformer, a vaporizer, a fuel cell stack, an afterburner and other assemblies and components of a fuel cell unit or system, More specifically, gas pressure can be used to control and deliver gaseous reformable fuels and/or liquid reformable fuels in the delivery systems and methods of the present teachings. The delivery systems and methods also can apply to the delivery of a liquid reactant such as water and gaseous reactants such as an oxygen-containing gas (e.g., air) and steam.
