Embodiment Construction

[0012] The invention will be further described below.

[0013] Such as figure 1 and figure 2 As shown, a new process burner system includes a process burner 1, and the process burner 1 includes an intermediate oxygen channel 2, an outer epoxy channel 3, and an intermediate oxygen channel 2 and an outer epoxy channel 3. A coal water slurry channel 4, a cooling water channel 5 is arranged between the outer epoxy channel 3 and the coal water slurry channel 4;

[0014] The front end of the process burner 1 is also connected with a mixing atomizer 6. The mixing atomizer 6 includes a mixing chamber 7 and a premixing chamber 8. The mixing chamber 7 is composed of CO on both sides. 2 Channel 9 and located in CO 2 The coal-water slurry passage 4 between passage 9 is formed, and the dividing plate 10 between adjacent passages is Y-type, and premix chamber 8 is positioned at each passage rear end, and the rear end of premix chamber 8 offers discharge hole 11, described The discharge...

Abstract

The invention provides a novel technological burner system. The novel technological burner system comprises a technological burner, wherein the technological burner comprises a middle oxygen channel,an outer ring oxygen channel and a coal water slurry channel located between the middle oxygen channel and the outer ring oxygen channel; a cooling water channel is arranged between the outer ring oxygen channel and the coal water slurry channel; the front end of the technological burner is further connected with a mixed atomizer; the mixed atomizer comprises a mixing chamber and a pre-mixing chamber; the mixing chamber consists of CO2 channels at two sides and the coal water slurry channel located between the CO2 channels; a separation plate between every two adjacent channels is Y-shaped; the pre-mixing chamber is located at the rear end of each channel and a discharge hole is formed in the rear end of the pre-mixing chamber; the discharge hole is communicated with a feeding opening of the technological burner. By adopting the technological burner, the contact specific surface area between CO2 and oxygen gas can be larger and gasification reaction is more rapid, so that the problem that the oxygen gas is excessive in a combustion region and local area is greatly solved.

Description

technical field [0001] The invention relates to a novel process burner system. Background technique [0002] Texaco's coal-water slurry gasification technology has been industrialized in China for many years. This technology has the advantages of low environmental pollution and high degree of automation. The process burner has an important impact on the long-term and efficient operation of the Texaco gasifier. At present, the external mixing three-channel burner is mainly used in industrial production. The process oxygen is ejected at a high speed to impact the coal-water slurry, so that the water The coal slurry is crushed and atomized to become small droplets of coal slurry suitable for combustion. The atomization effect of the process burner with this structure is improved compared with that of the two-channel burner, but due to the jet flow of a single nozzle and the limitation of the height-to-diameter ratio of the gasifier, the turbulent mixing in the furnace is relat...
