Why is the three times wind mouth of industrial boiler generally arranged on the upper part of each burner angle?
The characteristics of the three times wind are low wind temperature, high moisture content, high wind speed, and large wind volume (about 20% of the total wind volume, and about 10% of the coal powder), which has a great impact on the combustion of the furnace. Therefore, it is generally arranged on the upper part of the burner to mix the three times wind flow as much as possible with the main coal powder gas flow in the burnout stage of the main coal powder gas flow, so as to avoid affecting the ignition and combustion of the main coal powder gas flow.
