Problems solved by technology

[0003] Coal tar is derived from coal, and has the characteristics of high viscosity, high carbon content, and high ash content. During use, the burner is severely worn and the atomization effect is poor; incomplete combustion produces black smoke; it is easy to generate carbon black and coke during combustion Problems such as blocked guns

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0023] Such as Figures 1 to 7 As shown, a burner of a coal tar oxy-fuel combustion control system is designed in the form of a coaxial sleeve. Made of high temperature stainless steel material.

[0024] In the middle of the gun core 2 is the fuel channel of the burning gun, such as coal tar inlet 1 leading into coal tar; the gap between the gun core 2 and the gun body 3 forms the atomized gas channel of the burning gun, and passes through compressed air; the gun body 3 and the gun body The gap between the shells 7 is a combustion-supporting gas passage for oxygen.

[0025] The front end of the gun core 2 is a tapered fuel injection port 13, and the middle of the gun core 2 is a slender stainless steel oil pipe; t...

Abstract

The invention discloses a burning lance for a coal tar oxy-fuel control system. The burning lance comprises a lance core, a lance body, a lance shell and a connector which are sequentially arranged from inside to outside in a sleeving manner. Gaps are formed between every two of the lance core, the lance body and the lance shell. The lance body and the lance core extend out of the lance shell together. The lance core is provided with an axial through hole. By the adoption of the gas atomization technology, the atomization parameter matching is reasonable, so that the atomization grain size of coal tar is more fine and even, the good adjustment feature is achieved, and the atomization quality of the coal tar is improved; and oxy-fuel is adopted, the content of oxygen is increased greatly relative to that of air burning, dust in the coal tar is more fully burned, the problems that smoke is generated due to incomplete combustion of the coal tar is eliminated, and the phenomena that the coal tar is coked and blocks the gun are reduced remarkably.

Description

technical field [0001] The invention relates to the technical field of industrial oxy-fuel combustion equipment, in particular to a burner for a coal tar oxy-fuel combustion control system. Background technique [0002] Coal tar, also known as coal paste, is a black or dark brown viscous liquid obtained during the dry distillation of coal. It has a special odor, is flammable and corrosive. Compared with natural gas and heavy oil, coal tar has a slightly lower calorific value, but its price is relatively low. Therefore, many enterprises switch to burning coal tar in order to reduce production costs. [0003] Coal tar is derived from coal, and has the characteristics of high viscosity, high carbon content, and high ash content. During use, the burner is severely worn and the atomization effect is poor; incomplete combustion produces black smoke; it is easy to generate carbon black and coke during combustion Problems such as blocking guns. Contents of the invention [0004]...
