The Ways Assessment of Direct Production Electricity and Heat from Hydrogenous Fuel Based on Biogas for Autonomous Consumers
Based on the research of the fuel cell in the direct supply of hydrogen fuel with residual methane content (2-7%) confirmed the possibility of the fuel system operation in an efficient mode. The possibility of using a considerable potential "weak" biogas with a relatively low concentration of organic ingredients to produce electricity and heat in autonomous power engineering is shown. Energy potential reserve the purged fuel markedly increases with the content of methane in the original fuel and increases the role of the thermal component of the divided energy flow to about 20-26%. Integrated use of fuel energy potential with residual methane content allows to provide total effective efficiency ~ 40%. Possibility of electricity generation on the basis of complex use of organic and hydrogen fuel at creation of objects of distributive systems of power supply will approach energy sources to the consumer, having increased energy-economic indicators and efficiency of fuel use.
