Abstract

The invention discloses a multifunctional integrated start-up burner which comprises a central shell, an outer shell and an ignition rod, wherein the central shell and the outer shell are integrated;the lower end of the ignition rod is inserted into the central shell through the top of the central shell; the lower end of the ignition rod is provided with a high-energy igniter; the side surface ofthe central shell is provided with a start-up fuel inlet and a waste water inlet, wherein the start-up fuel inlet and the waste water inlet are positioned outside the outer shell; and the side surface of the outer shell is provided with an accelerant inlet. A combustion improver channel is formed between the outer part of the central shell and the inner wall of the outer shell, a start-up fuel-waste water channel is formed between the ignition rod and the inner wall of the central shell, and an atomizer is arranged between the ignition rod and the central shell, wherein the atomizer is positioned at the working medium outlet at the lower end of the start-up fuel-waste water channel, and the burner can realize the functions of starting ignition and putting waste water into the burner afterstarting ignition, and can also realize cooling and sealing of the start-up burner.

Description

technical field [0001] The invention belongs to the technical field of energy and chemical industry, and relates to a multifunctional integrated start-up burner. Background technique [0002] In the past ten years, affected by environmental factors, the coal chemical industry has gradually developed in a large-scale and green direction. Dry pulverized coal pressurized gasification technology has been rapidly developed and widely used in the coal chemical industry. The pulverized coal burner is the core component of the key equipment gasifier in the dry pulverized coal pressurized gasification technology, and the ignition start-up burner is the key component of the main pulverized coal burner. The performance and service life of the ignition start-up burner directly affect whether the pulverized coal burner can be fed smoothly and its long-term stable operation. [0003] The whole process of feeding the conventional pulverized coal burner is relatively long, and after the f...
