Biomass fuels have a wide range of different physical and chemical properties. Sustainability of biomass fuels and combustion facilities are depends on the characteristics of these biomass fuels.
Hi Saad El-Sayed Sir,
The syngas composition obtained from biomass gasification using air as oxidizer is predominately chemical equilibrium governed. Hence the empirical chemical formulation of biomass obtained from proximate and ultimate analysis with the understanding of volatile stoichiometry is enough to obtain the syngas composition. However, if the target is prediction of CO emissions from this biomass derived syngas, kinetics is important. Have a look a

Characterization of biomass is done to estimate C/H ratio. The concept of gasification deals with conversion of low C/H ratio fuel to High C/H ratio gaseous fuels. Such that the fuel gas has more hydrogen content . This will improve the calorific value @ Saad El-Sayed
Dear Saad El-Sayed,
During gasification, combustion or other biomass conversion technologies, countless chemical reactions occur. These reactions are extremely susceptible to chemical compositions of reactants and even products, which have appropriate interactions with each other during the process. Therefor, the chemical composition of biomass fuels are really effective factor on the quantity and the quality of gaseous products from the viewpoint of kinetics principles.
I can suggest this book as a comprehensive study source of biomass fuels and their conversion technologies:
Basu, P. (2010). Biomass gasification and pyrolysis: practical design and theory. Academic press.
Chicago
Biomass can be used as fuel for combustion. However, it is important to understand the technical implications of using different biomass as fuel. For instance, some biomasses (such as manure) can produce corrosion on the piping, some others have low heating value, thus, abundant biomass must be used to fulfill the requirements.
Another use of biomass in combustion facilities is converting the biomass to a suitable fuel for further combustion. Biodigestion, pyrolysis, and gasification are examples of such applications.
All these processes are highly susceptible to operating conditions ( Temperature, residence time, pressure). As such, it is important to understand the characteristics of the biomass beforehand.
For this answer, I suggest reading this article:

Dear Saad El-Sayed ,
From an industrial perspective, is important to know these interactions in combustion facilities to:
- Ensure biomass hydrocarbon total conversion to CO2+H2O, avoiding emissions of intermediates such as PAHs or CO for example and loss of efficiency (getting all the chemical energy from the fuel)
- Understand interactions of the inorganics with the furnace wall and heat exchanger tubes to avoid depositions that will affect integrity of the boiler through corrosion and a loss of heat transfer therefore boiler efficiency.

As a material scientists or product designer: The study of properties/ characteristics of biomass helps you to design the system. For example volatile matter content helps you to predict the maximum temperature of combustion and this data further helps you to choose appropriate materials for your combustion chamber/reactor. Simillarly, it is very important to know the inorganic materials present in biomass before designing a combustion chamber to stop corrosion of reactor due to formation of unknown compound which may react with the chamber material.
