... for the top 11 reactions from the NUIG Syngas mechanism for 2:1 H 2 :CO mixtures with dilution by CO 2 varying from 0% to 30%. At this H 2 :CO ratio, increasing CO 2 concentration causes increases in sensitivity coefficients for almost all the top reactions, and no reaction experienced a decrease...

... zone makes LP type of combustors a candidate for upstream flame propagation (i.e., flashback) in the premixer that is typically not designed to sustain high temperatures. Moreover, there has been a recent demand for fuel-flexible gas turbines that can operate on hydrogen-enriched fuels like Syngas...

...-ready CO 2 sequestration conditions. The results of the study indicate that hybrid SOFC systems could achieve electric efficiencies approaching 66% [lower heating value (LHV)] when operating fueled by coal-derived clean syngas and without carbon dioxide capture. The system concept integrates SOFCs...

...B. B. Sahoo; U. K. Saha; N. Sahoo Syngas, an environmentally friendly alternative gaseous fuel for internal combustion engine operation, mainly consists of carbon monoxide (CO) and hydrogen (H 2 ). It can substitute fossil diesel oil in a compression ignition diesel engine through dual fuel...

... was measured using a Uras 14 device also from ABB Automation. Here, the principle is based on the absorption of infrared radiation in polyatomic gases. As the prerequisite for all test with syngases, it had to be shown first that the burner geometry optimized in the water channel allows proper flame...
