Heating with biomass and thermal storage also provides the possibility to combine other renewable heating sources such as solar heating systems. Finally, new technologies allow for automatic operation and feeding of the boilers, which eliminates a negative aspect of this heating method.
The preferred approach of co-firing biomass in a PC boiler is to feed the biomass into a dedicated mill so it can be dried at around 100 C (200 F) while the coal is dried at around 275 C (525 F).
Combustion, gasification and pyrolysis are all thermochemical processes to convert biomass into energy. In all of them, the biomass is heated to evaporate water and then to cause pyrolysis to occur and to produce volatiles.  2 Combustion Biomass combustion refers to burning fuel in a boiler, furnace or stove to produce heat.
A boiler is an enclosed vessel in which water is heated and circulated, either as hot water, steam, or superheated steam for the purpose of heating, powering, and/or producing electricity. The furnace of the boiler is where the fuel and air are introduced to combust; fuel/ air mixtures are normally introduced into the furnace by using burners

Basic principles of biomass combustion. Biomass can be converted into energy (heat or electricity) or energy carriers (charcoal, oil, or gas) using both thermochemical and biochemical conversion technologies. Combustion is the most developed and most frequently applied process because of its low costs and high reliability.
In brief, biomass gasification technology uses biomass as raw materials, oxygen, steam or hydrogen as agent, and turn the biomass into combustible gas through chemical reaction at high temperature. The combustible gas can be used in industrial and agriculture production, such as power generation, supplying heat, methanol and ethanol synthesis.
A single-stage biomass boiler, operated in an on/off mode can produce condensation within the combustion chamber, resulting in the build-up of creosote and organic acids. This situation worsens if the biomass used is too wet and the biomass boiler is located outside, with poor insulation.
Biomass combustion is clearly a proven technology, but design improvements over the past couple of decades have helped to increase its efficiency, reduce emission levels and reduce costs. At the same time, the creation of professional certification programs for installers and inspectors has helped to boost the safety of biomass combustion systems.
