Abstract

The application of the present invention provides a device and method for configuring the secondary air of a boiler. The power unit sends fresh air to the secondary air ducts through the secondary air main pipe, and the fresh air in the secondary air duct is in the power unit of the secondary fan. Under the action, the swirling fluid is blown into the swirl fluid at a high speed through the swirl fluid inlet pipe, and high-speed rotation is generated inside the swirl fluid. The negative pressure sucks the fuel volatiles in the boiler under the swirl fluid into the swirl fluid, mixes it with the fresh air rotating at high speed, and blows it out at the outlet above the swirl fluid into the inside of the furnace. The flow rate of the mixed gas blown out by the swirl fluid is relatively large, and it plays the role of adding fresh air and stirring the flue gas in the furnace, so that the boiler fuel is fully contacted with the fresh air.

Description

technical field [0001] The application of the present invention provides a device and method for configuring boiler secondary air, which relates to the field of technical transformation of small and medium-sized industrial boilers. Energy saving and emission reduction, the purpose of improving the environment. Background technique [0002] When the boiler is burning, because the primary air of the boiler cannot be well mixed with the volatiles of the fuel in the furnace, the volatiles of the fuel cannot be fully combusted, and the incompletely burned volatiles of the fuel are easily drawn away by the induced draft fan of the boiler to form black smoke. In order to fully burn the volatile matter of the fuel, eliminate black smoke and make full use of energy, a certain amount of fresh air must be added above the furnace, so that the added fresh air is fully mixed with the volatile matter of the fuel and the fuel is obtained. Fully burn, save energy and eliminate black smoke....
