Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.

In China, several million tons of oil is consumed annually to ignite pulverized coal (PC) when the boiler starts up, as well as to stabilize the combustion. In this paper, one oil-free ignition technique was studied for oil-saving, by means of which high temperature air was used to ignite PC. Numerical simulation was carried out to recognize the exact flow and combustion characteristics in a three-stage coal ignition burner. Several important factors influencing the ignition of PC were analyzed, including PC concentration, the inlet velocity of primary air flow, the velocity of high temperature air and PC fineness. The simulation results were in accordance with the experimental data. It is believed that the results can be helpful to the operation and optimization design of three-stage coal ignition burner.
