Abstract

The invention discloses a novel wake flow combustor with a random accumulation structure. The novel wake flow combustor comprises a combustion cavity, the bottom of the combustion cavity is connectedwith a gas mixing pipeline, a gas backflow area, two layers of foamed ceramics and an accumulation chamber are sequentially arranged in the combustion cavity from bottom to top, a Raschig ring is arranged at the bottom in the combustion cavity, the two layers of foamed ceramic are supported through the Raschig ring, and the gas backflow area is formed; and silicon-containing aluminum oxide pelletsare randomly accumulated in the accumulation chamber to form a porous medium layer, the combustion rate is increased through the silicon-containing aluminum oxide pellets, and the tempering phenomenon in the combustion process is reduced.

Description

technical field [0001] The invention belongs to a wake burner visualization test bench device, in particular to a novel wake burner with random stacking structure. Background technique [0002] With the development of science and technology economy, my country's energy consumption is increasing, and at the same time, the pollution caused to the environment is also becoming more and more serious. Among them, fuel combustion is one of the main ways to obtain energy, so reducing combustion emissions and increasing combustion efficiency have become two major challenges for energy-saving and emission-reduction strategies. Porous media combustion is a new high-efficiency and low-pollution combustion method filled with porous media in the combustion device, also known as "filter combustion" [Wang Bo, Xue Guocheng, Zhang Long, Shang Qinglong. Premixed combustion in inert porous media Research Progress [J]. Energy Saving Technology, 2019, 37(03): 231-238.]. Porous media refers to a...
