[Gasification] RPS experience with linear hearth

[Tom Miles]

This topic has gone out of control and must end. Please take your personal
views offline. 

This is not the place for accusations and trash talk. (We can leave that to
professional athletes.) Stick to technical discussion of gasification. 

Ownership of the designs used in this discussion are currently confused and
not appropriate for discussion on this forum. The "owners" can report to us
only after they have sorted things out amongst themselves offline. That
could take months.  

If the data, like the gas analysis,  is not believable show example so of
what is. A useful model of gas analysis was published this week by the
American Chemical Society:

This paper presents a mathematical model for biomass gasification processes
developed in the equation solver program Engineering Equation Solver (EES)
with an implemented user-friendly interface. It is based on thermodynamic
equilibrium calculations and includes some modifications to be adapted to a
real process, in which only a partial approach to chemical equilibrium is
achieved. The model can be used to predict the producer gas composition,
yield, and heating value for a certain biomass with a specific ultimate
composition and moisture content. It has been validated with published
experimental data from different authors for downdraft, fluidized-bed
gasifiers and different biomasses, showing good agreement between reported
data and modeled values. In addition, it has been used to evaluate the
influence of different operating parameters [equivalence ratio (ER), air
preheating, steam injection, and oxygen enrichment] on producer gas. The
model predicts the behavior of different kinds of biomass and becomes a
useful tool to simulate the biomass gasification process by allowing its
integration in complete energy supply systems, such as co-generation plants.
