Abstract

The invention discloses an ear cap type high-temperature-resistant premixed combustion nozzle. The muzzle comprises a first shell, a plurality of flow guide plates, a first channel, a second shell, asecond channel, a water inlet mechanism and a water outlet mechanism, wherein the plurality of flow guide plates are uniformly distributed along the outer surface of one end of the first shell; the first channel is coaxially formed inside the first shell, one end of the first channel is of a cylindrical structure, and the other end of the first channel is of a circular-truncated-cone-shaped structure with the radius gradually decreasing; the second shell is coaxially arranged outside the first shell in a sleeving mode, and the second channel is coaxially arranged between the first shell and the second shell; and the water inlet mechanism is arranged outside the second shell in a sleeving mode, and the water outlet mechanism is arranged between the water inlet mechanism and the second shelland communicates with the water inlet mechanism. Through cooperation between the first channel and the second channel, inlet fuel is premixed, a nozzle is cooled through the water inlet mechanism, and the nozzle is prevented from deforming. The invention further provides a control method of the ear cap type high-temperature-resistant premixed combustion nozzle.

Description

technical field [0001] The invention relates to an ear cap type anti-high temperature premixed combustion nozzle and a control method thereof, belonging to the field of boiler burners. Background technique [0002] At present, in the boiler furnace, when the furnace load suddenly rises due to the burning of low-quality coal or abnormal operation of the boiler, the temperature of the burner nozzle shell will be too high and deformed, which will affect the service life of the nozzle and is not conducive to the stability of the furnace Combustion will affect the safe operation of the unit in the long run. The premixing method of pulverized coal and air also affects the stability and uniformity of combustion in the furnace. Premixing combustion of pulverized coal and air is a common combustion method for boiler units. For pulverized coal gas entering the furnace, the flame will be delayed if the temperature is too low. Experimental studies have found that increasing the temper...
