Experiments on the Dynamic Behavior of the Chemical Looping Combustion Process

The dynamic operation of thermal power plants becomes more and more important due to more diverse and volatile power sources. Load changes of biomass, bituminous coal and methane were conducted during six experimental runs in a chemical looping combustion pilot plant which combines power generation and CO2 capture. The resulting step responses of the hydrodynamics and gas concentrations were compared to each other to understand the transient behavior of the interconnected fluidized bed system. The influence of the fuel rate and solid circulation on the response time and intensity was assessed. Chemical looping combustion combines power generation and CO2 capture. In a pilot plant, load changes with biomass, coal and methane were conducted to understand the transient behavior of the interconnected fluidized bed system. An evaluation of the fuel load and circulation rate on the response time response time and intensity was performed.
