Low-nitrogen energy-saving burner for carbon roasting furnace

Abstract

The invention provides a low-nitrogen energy-saving burner for a carbon roasting furnace. The low-nitrogen energy-saving burner comprises a burner shell, a motor, a natural gas nozzle, a premixing turbine, a natural gas delivery vertical pipe and a natural gas delivery horizontal pipe. The motor is mounted on the upper portion of the burner shell. The motor is fixed to the interior of the shell through a motor fixing bracket. The natural gas nozzle is arranged in the burner shell and fixed to the interior of the burner shell through screws. The premixing turbine is mounted at an inlet of the natural gas nozzle. An atomizing nozzle is mounted on the premixing turbine. One end of the natural gas delivery vertical pipe is fixed to the burner shell through a pipe clamp, and the other end of the natural gas delivery vertical pipe is connected with the natural gas delivery horizontal pipe through a three-way pipe. The natural gas delivery horizontal pipe is fixed to the burner shell throughan external fixing nut and an internal fixing nut. The natural gas delivery horizontal pipe is connected with the atomizing nozzle. A pressure detection nozzle is mounted at the closed end of the natural gas delivery vertical pipe through a fixing nut. The low-nitrogen energy-saving burner has the characteristics of being long in flame jet flow, sufficient in natural gas burning, long in service life, energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the field of burners, in particular to a low-nitrogen energy-saving burner for a carbon roaster. Background technique [0002] The burner device used in the traditional carbon roaster is called Venturi burner. The Venturi burner has weak firepower, the flame is like a lump of fire, and the temperature rise rate of the furnace chamber is slow, resulting in uneven heating of carbon products, resulting in carbon products The quality of the furnace is not up to the standard, and even the carbon products are burned, the structure of the inner wall of the furnace and the baking bracket of the carbon products are damaged. Due to the insufficient firepower of the burner, the volatile matter of the carbon products has not been fully burned and utilized. [0003] In addition, the traditional Venturi burner itself also has quality defects, and its service life is short, generally 3-6 months, and it is time-consuming and laborious to maint...

Problems solved by technology

[0002] The burner device for traditional carbon roasting furnace is called Venturi burner. The Venturi burner has weak firepower, the flame is like a lump fire, and the temperature rise rate of the furnace chamber is slow, resulting in uneven heating of carbon products, resulting in carbon products The quality of the carbon products is not up to the standard, and even the carbon products are burned, the structure of the inner wall of the furnace and the baking bracket of the carbon products are damaged. Due to the insufficient firepower of the burner, the volatile matter of the carbon products has not been fully burned and utilized.

[0003] In addition, the traditional Venturi burner itself also has quality defects, the service life is short, generally 3-6 months, and it is time-consuming and laborious to maintain during use, often requiring roasters to repair, which consumes a lot of labor costs
