Introduction to biomass boilers - TheGreenAge

A biomass boiler works in a very similar way to conventional boilers, combusting fuel to produce heat that is then used to heat water Biomass boilers are normally substantially bigger than their fossil fuel-burning brothers though, for a number of reasons Firstly since they are burning wood pellets as opposed to gas, the boiler needs to be ....
