ApplicationNo./PatentNo.: 200720 106568
The utility model relates to an energy-saving pulverized coal burner with stable combustion teeth, which comprises a burner body, a combustion chamber and an oil combustion chamber, and is characterized in that the inner wall of the outlet of the combustion chamber is provided with a plurality of protruding stable combustion teeth. After adopting the above structure, the primary air powder carries the pulverized coal into the combustion chamber, and the high-temperature oil flame sprayed by the combustion chamber and the oil combustion chamber is mixed and ignited for combustion; As the outlet of the combustion chamber is provided with a plurality of protruding stable combustion teeth, the air powder burns more violently and completely under the disturbance of the stable combustion teeth, which improves the flame temperature and combustion efficiency and achieves the purpose of energy saving. The burner with this structure can ensure the stable combustion of the boiler under low load, improve the stability and economy of the boiler operation, and greatly reduce the number of fuel injection and combustion-supporting of the boiler.
