Not really. A yellow redstone engine will produce 1 MJ per second, which is 0.05 MJ/t. That means that with five sides connected to redstone engines that are heated up (which takes quite a while), you will only get 1/4 MJ/t (you will get a bit more if they are alternating between yellow and red, but not enough to make a difference). The mininium power usage of the powered furance is 0.5 MJ/t. This means that it will be working a little bit more then half the time at minimuim speed. This could work if you are cooking food (which only uses 40 MJs), but for other stuff that will take ages (they require 160 MJs). The pulverizer requires 1 MJ/t, so it will be even slower. Don't even think about a magma crucible, which requires 7.5 MJ/t. Also, because redstone engines can't output power to conductive pipes or redstone energy cells, you can never have more then five powering one machine, assuming you want to access it.

So yeah, not really.
