three-dimensional simulation of combustion gases flow inside a flare thermal chimney: effects of layer distance

The use of solar chimney power plants (scpp) to produce clean and environmentally friendly energy has received lot of attention in recent decades. however, flare chimney power plant (fcpp) is a new technology for electricity generation as chimney gases contain a significant amount of thermal and kinetic energy. the main goal of this research is to design a double-walled thermal tower to burn refinery waste gases to produce electricity from the energy of the combustion gases. the new design contains a double-layered chimney, combustion chamber, canopy, and flares. using commercial software the effects of canopy angel, fuel flowrate, chimney height, layer distance, and flares position effects on the electricity production were studied. it was found that the average gas velocity and density inside the throat area changes nonmonotonically by changing the layers distance.
