Fuels for cogeneration systems
This chapter will highlight the properties of fuels of interest for cogeneration systems and discuss the consequences for the combustion process and the emissions. The fuel properties partly determine the fuel efficiency and the emissions. Also combustion velocity and combustion stability are important issues. Examples of typical fuel properties are the volumetric or mass-based heating value and the minimum specific air requirement for complete combustion. The ignition range and autoignition properties are other properties of interest. Exceeding the fuel quality range for which the process has been tuned can introduce serious safety and performance issues. There is a direct relationship between the fuel composition and the carbon dioxide (CO2) emissions, but also other undesirable combustion end products depend on the fuel composition.
