With the TE gui there is not need for router of logi-pipes why over complicate this, line of TE furnaces pipe wood in one side/top/bottom, pipe charcoal out any of the reaming 2 sides, this is the whole idea of TE gui to automate small machine networks, for my early game power I hook up 2 TE steam engines to each furnace so 5 furnace = 10 engines = 40 mjpt, this setup the wood will fill the first furnace on the line then the next & so on, with a small mfr farm easy for for early game, you will have more that enough wood to run 8 furnaces so that 16 engines @ 4 mjpt, or pipe into boiler to make steam, but early game mfr/TE AA/furnaces & engines are good renewable power supply.
