Embodiment Construction
[0014] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection scope of the present invention are not limited thereto.
[0015] Such as figure 1 Shown, this petroleum coke powder burner comprises feed pipe 1, primary wind turbine 2, secondary wind turbine 3, petroleum coke powder concentrator 5, combustion cylinder 14, described feed pipe 1, primary wind turbine 2, two The secondary wind turbine 3 and the combustion tube 14 are arranged coaxially in sequence. The primary wind turbine 2 and the secondary wind turbine 3 respectively form a rotating jet feeding system for the primary wind and the secondary wind. The primary wind turbine 2 is set in the On the feed pipe 1, the primary wind turbine 2 and the outlet of the feed pipe 1 are connected to a primary mixing zone 4 for primary mixing of petroleum coke powder particles and air, and the downstream of the primary ...

The invention discloses a petroleum coke powder combustor, which comprises a feeding pipe, a primary air turbine, a secondary air turbine, and a combustion cylinder coaxially arranged in turn. A primary air passage is provided with a petroleum coke powder concentrator inside; a secondary air passage is sleeved outside the combustion cylinder and is communicated with the secondary air turbine; thepetroleum coke powder concentrator is respectively communicated with a thick petroleum coke powder passage and a thin petroleum coke powder passage; the thick petroleum coke powder passage and the thin petroleum coke powder passage are respectively communicated with a first-stage combustion chamber and a second-stage combustion chamber; the first-stage combustion chamber is communicated with the second-stage combustion chamber; and the second-stage combustion chamber and the secondary air passage are connected to a hearth. The two-stage combustion technology is adopted, so the space and time for combusting petroleum coke powder airflow are enlarged and prolonged. The primary air turbine feeds primary air to enhance the disturbance; simultaneously the secondary air turbine feeds secondary air to form rotary jet flow to entrain high-temperature flue gas, so that the petroleum coke powder is easy to fire.
Description
technical field [0001] The invention relates to a petroleum coke powder burner. Background technique [0002] Petroleum coke is a product obtained by distilling crude oil to separate light and heavy oil, and then thermally cracking the heavy oil. From the appearance, the coke is black lumps of irregular shape and size (or Particles) with metallic luster, coke particles have a porous structure, the main element is carbon, accounting for more than 80wt%, and the rest are hydrogen, oxygen, nitrogen, sulfur and metals. It is mainly used to produce carbon products, such as graphite electrodes and anode arcs, for steelmaking, non-ferrous metals, and aluminum smelting; to produce silicon carbide products, such as various grinding wheels, sand skins, sandpaper, etc.; to produce commercial calcium carbide for production Synthetic fiber, acetylene and other products; also can be used as fuel. [0003] As crude oil becomes heavier, the market for heavy fuel oil shrinks, and the envir...
