Evaluation Of The Advanced Low-nox Burner Exxon

FGT can be divided into two general categories: dry and wet. The majority of dry processes involve a gas-phase reaction with a reducing agent, NH3, which is added to the flue gas. If the NH3 is injected into the superheater region of the boiler where temperatures are high (1,740°F), a catalyst is not necessary.

Frontiers | Air and Steam Gasification of Almond

Experiments were performed on a laboratory scale fluidized bed gasifier to characterize the gasification products of almond shell and hull removed in nut processing operations and to determine the effect of gasifying media on bed agglomeration. The higher heating value of syngas during air gasification of almond biomass ranged from 4 to 6 MJ m−3 while gas concentrations ranged from 14 to 18%
