TL;DR: In this paper, an afterburner for internal combustion engines mixes exhaust gases from an exhaust manifold of an engine with a stream of compressed air to ignite the unburned gases which then pass over heating grids.
Abstract: An afterburner for internal combustion engines mixes exhaust gases from an exhaust manifold of an engine with a stream of compressed air to ignite the unburned gases which then pass over heating grids. As the remaining unburned gases pass through the heated grids, they ignite and burn. The device includes means within an outer sleeve for cooling the afterburner.

12 May 1975TL;DR: In this paper, a vortical flow afterburner was proposed for afterburning of engine exhaust gases by mixing air with same, in which the exhaust gas flow was supplied substantially tangentially into a precombustion chamber disposed on the upstream side of a reaction chamber for producing a vorical flow of the exhaust gases, this vortial flow being then supplied into the central portion of the reaction chamber, and air is supplied substantially tainting into the reaction reaction chamber to insure combustion of exhaust gases.

TL;DR: In this article, a two-step turbulent combustion subgrid-scale model is employed for calculating carbon monoxide CO concentration, and the NO subgrid scale pollutant formation model is applied to the evaluation of the rate of NO formation.
Abstract: The k-equation subgrid-scale model is used for large-eddy simulation(LES) of the pollutant performance in the model afterburner with V-gutter flame stabilizer. A two-step turbulent combustion subgrid-scale model is employed for calculating carbon monoxide CO concentration. The NO subgrid-scale pollutant formation model is applied to the evaluation of the rate of NO formation. The EBU combustion subgrid-scale model is used to determine the chemical reaction rate. The heat flux model is applied to prediction of the heat flux. Agreement between the predictions and experiments shows that pollution formation subgrid-scale models can be used to predict pollutant emissions in an afterburner.
