Embodiment Construction

[0021] Below in conjunction with accompanying drawing, embodiment of the present invention is set forth:

[0022] The main body of the special burner for the coal-water slurry type cracking furnace has horizontally extending edges and the center is convex, forming a hollow pre-combustion chamber 8; The slurry spray gun 1 is centered with a protective sleeve 2, a gas jacket 3, a primary air pipe 4 and a gas air sleeve 5 in sequence. The primary air pipe 4 and the gas air sleeve 5 are respectively provided with impeller swirlers 7 to ensure that the primary air and the gas air have a tangential velocity. The secondary air pipe 9 is connected to 10 secondary air outlets 10 provided on the top side of the pre-combustion chamber 8, and each secondary air outlet 10 is evenly spaced on the wall of the pre-combustion chamber 8, and the distance from the corresponding radial centerline Form the same rotation angle between them, so that they are arranged in a clockwise direction; on th...

Abstract

The invention relates to a combustor technology, and aims to provide a combustor special for a coal water slurry combustion type cracking furnace. A combustor main body is provided with a hollow pre-combustion chamber; a coal water slurry spray gun is arranged on the top of the pre-combustion chamber; a protecting sleeve, a gas jacket, a primary air pipe and a gas air sleeve are sequentially sleeved around the coal water supply spray gun; a secondary air pipe is connected to a plurality of secondary air outlets which are formed in the side surface of the top of the pre-combustion chamber; the secondary air outlets are uniformly distributed in a wall of the pre-combustion chamber at intervals; the same rotating included angles are formed between the secondary air outlets and the corresponding radial center lines; and an oil gun hole is also formed in the side surface of the top of the pre-combustion chamber, and an oil gun is inserted in the oil gun hole. The combustor can be powered by fuels such as coal water slurry, light diesel oil and hydrogen-methane / natural gas; the coal water slurry is mainly used and can replace the hydrogen-methane, and products with high additional values can be produced; and the combustor is switched over quickly and conveniently in a running process so as to meet requirements on various working conditions, labor can be saved by an automatic control system, and economical efficiency and operability are improved.

Description

technical field [0001] The invention relates to a burner, in particular to a special burner for a water-fired coal slurry cracking furnace. Background technique [0002] As a strategic resource, oil is also a non-renewable resource, which plays a major role in the country's economy and national defense security. With the development of industrialization, crude oil production in 2010 has exceeded 200 million tons, an increase of 6.9% over the previous year, the highest growth in recent years. The rapid development of the national economy has led to a great increase in the domestic demand for oil. Although my country is a major oil-producing country, most of my country's oil still relies on imports. In 2010, my country's crude oil imports reached 239 million tons, an increase of 17.5%. There are also many hidden dangers in China's oil industry caused by excessive oil imports. For example, the contradiction between oil supply and demand has led to excessive dependence on oil i...
