Improvement of Thermal Processes for Using Residues from Bioethanol and Sugar Production in Brazil: Experiments and Proposed Optimization Measures

Table 1

Overview of the characteristic numbers [11].

Equation 1	reaction front velocity
Equation 2	ignition rate
Equation 3	mass conversion rate
Equation 4	specific heat release rate

x = height of the reactor [m]; = bulk density of the initial fuel [kg m⁻³]; = fuel mass converted [kg]; A= cross-section of the combustion vessel [m²]; = ash content of the fuel [-]; and LHV = lower heating value [MJ/kg].
