Feasibility of Studying Fuel Mixer Design for High Power Engines Using Completely Biogas

Abstract:

Nowadays, the original source of mineral fuel for engines was depleting increasingly while combustion products make the environment to be polluted, CO₂ emission which caused many greenhouse gases; this also makes crude oil prices fluctuate and rise. They tend to use biogas as a fuel for internal combustion engines which have been interested in the powerful countries. Supply of biogas from the waste of farms, flour production, fish processing, landfills, etc., with hundreds or thousands of cube meter of biomass daily leads demand on high-power generators using biogas in order to make good use of produced gas. This article introduces a technology solution for fuel engines using purely large-capacity biogas and operating under compression type fire. Accordingly, the tubular biogas Venturi mixer with electronic controller has been used to supply the mixture of fuel to engine. The CDI-DC ignition circuit provides a high voltage of 28kV for forced combustion of the mixture. Experimental results show that the mixer operates stably, well controlled and allows adjusting the ratio of air/fuel, as well as easily changing its speed when it is used as a hybrid engine for the generator. Some results of performance evaluation of biogas mixer will be presented in this article.
