Can I use biomass instead of normal fossil fuel in any installation without conversion?

No, usually the installation does require some adjustments as far as preliminary treatment goes. It might not need much adjustment, but this is strongly related to the type of installation involved. In practice, a rule of thumb is that installations that run on viscous fossil fuels (read: fuel oil) need only minor adjustments and that an installation that runs on natural gas or light oil will need more adjustments.   
We have a lot of experience in the area of converting various types of installations, and can provide extensive support.
