I already got you. you want to turn the maximum out of a boiler. that's okay... ECrownofFire mentioned that burning biofuel inside a boiler is a bad idea in any way.... it is not.
firstly, whoever uses biofuel also runs some kind of farm that generates tons of biofuel, maybe even more than he can use in a boiler, since everyone is afraid that the boiler can be out of fuel, the fuel supply could be even superiour than the boiler consumption.
that leaves us with a system, where just the boiler efficiency matters.
and the boiler efficiency is best in a 36 hp or lp (it doesn't matter) boiler, that is constantly supplied with fuel. and it doesn't matter how the fuel is generated. biofuel has the nice advantage that it just takes a treefarm to produce tons of apples and saplings, and it also creates tons of wood as by-product.
so, the boiler is the best way, IF the fuel is constantly supplied and the steam is constantly used (excess steam of the boiler just vanishes).
