TL;DR: In this article, the influence of pressure on the combustion characteristics (i.e., ignition, volatiles combustion, char combustion) of a single lignite particle was investigated in a pressurized visualized fluidized bed combustor under O 2 N 2 and O 2 CO 2 atmospheres.

TL;DR: In this article, the combustion behavior of single char particles were investigated in a transparent fluidized bed combustor under different operating conditions (i.e., gas atmosphere, oxygen concentration, coal rank, location, fluidization number, particle size, and bed temperature).

TL;DR: In this paper, experiments were carried out in two pressurized fluidized bed (PFB) devices (a hot PFB and a visual PFB) both operated under high temperature (20-800°C) and high pressure conditions (0.1-1.0

TL;DR: In this paper, the combustion and kinetics characteristics of lignite char particle were studied in a fluidized bed (FB) reactor under N2, CO2 and H2O atmospheres with different O2 concentrations (15% −27%) and bed temperatures (Tb, 837 − 937°C).

TL;DR: In this article, a fuel-staged oxy-CFB (oxy-fuel circulating fluidized bed) combustion technology is proposed to extend the operation range of an existing air-fired CFB boiler retrofitted for oxy-fuel operation.
