The concentration of hydrochloric acid in the exhaust fumes is well below the emission limit for this type of emission.
Carbon monoxide, thanks to the rotating tubular geometry of the gasifier, does not exceed the reference emission levels.
The concentrations of hydrofluoric acid are always below the limits of instrumental detection and therefore do not cause concern.
Even nitrogen oxides (NOx) always presents concentrations below the legal limits, therefore not being a critical parameter.
The concentration of sulfur oxides (SOx) is not even comparable to the legal limit while the total organic carbon concentration largely respects the limits.
Even in the case of polycyclic aromatic hydrocarbons, the limit value is not exceeded.
The concentration of dioxins in the absence of smoke treatment sometimes reach the legal limit; however, by applying our fume wash, this value is also pulled down together with any dust released into the atmosphere.
The sums given by the concentrations of cadmium and thallium and the concentrations of mercury have modest values and below the limits.
Finally, the sums of metal concentrations do not exceed any legal limit.
Therefore, the energy use of the poultry manure makes it clear that between the combustion and the gasification of the poultry manure it is the latter that turns out to be the best alternative since it involves lower, often null, emissions of carbon monoxide (CO), dust, nitrogen oxides (NOx) and sulfur oxides (SOx) which affect in particular the greenhouse effect, the acidification of rains and soils, the formation of photochemical smog, and ecotoxicity.
