Description

Technical Field

[0001] The utility model relates to the technical field of petroleum coke powder combustion, in particular to a petroleum coke powder cyclone combustion device. Background Art

[0002] Petroleum coke powder is the final product in the oil refining process. It has both the physical and thermal properties of oil. Using petroleum coke powder as a fuel to improve the utilization rate of oil energy is also an important step in energy conservation. Petroleum coke has high calorific value, low ash content, and low price, and has the basic conditions to be used as an industrial fuel.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN201983260U discloses a petroleum coke powder cyclone combustion device, including a petroleum coke powder burner, a control system and a high-temperature pulse ignition cap arranged on the nozzle and connected to the combustion chamber, a pulse action channel connected to the inside of the petroleum coke powder burner is arranged on the high-temperature pulse ignition cap, a pulse generation system connected to the inside of the high-temperature pulse ignition cap is arranged in the pulse action channel, and the pulse action channel is also connected to the ignition liquefied gas, and the atomizing gas system, the primary powder spraying channel, the pulse generation system and the ignition liquefied gas are all connected to the control system. The premixing and semi-premixing technology of petroleum coke powder and combustion-supporting air and the cyclone combustion control technology are adopted to achieve the effect of enhancing the combustion intensity and increasing the flame stability. The method of setting the flame spray hole on the high-temperature pulse ignition cap can adapt to the grinding particles of petroleum coke powder of different specifications, the burner does not coke, does not clog, and has a long service life. The method of burning petroleum coke powder through the combustion chamber and the combustion cavity of the high-temperature pulse ignition cap has stable combustion and high combustion efficiency.

[0004] Petroleum coke powder consumes a large amount of oxygen during the combustion process. Existing petroleum coke powder combustion equipment generally uses an air pump to introduce external air to add oxygen to the inside of the combustion equipment to facilitate the combustion of the petroleum coke powder. This method can only add gas to the inside of the device, but cannot mix the internal gas with the petroleum coke powder. The combustion efficiency of the coke powder is not high. At the same time, the coke powder of the existing combustion equipment is easily accumulated at the bottom of the combustion chamber, affecting the combustion efficiency of the coke powder.
