Embodiment 1
[0031] 1) The air is compressed by a Roots blower to a pressure of 0.036Mpa, then passed through a low-temperature air preheater, a medium-temperature air preheater and a high-temperature air preheater in turn, heated to 600°C and then sent into the combustion chamber;
[0032] 2) Fuel oil and additives are sent into the combustion chamber and mixed with hot air for combustion. The temperature is controlled at 1500°C. The hot smoke generated by combustion enters the reaction chamber through the throat, and the raw material oil is sprayed into the reaction chamber through the throat. Cracking reaction; the temperature is 1450°C and the pressure is 20Kpa.
[0033] 3) After the reaction, the product flue gas of the reaction is quenched by quenching water and then enters the waste heat boiler, and then passes through the high-temperature air preheater, medium-temperature air preheater and low-temperature air preheater to reduce the temperature of the product flue gas to 340 ℃;

Embodiment 2
[0045] 1) The air is compressed by the Roots blower to a pressure of 0.040Mpa, then passes through the low-temperature air preheater, the medium-temperature air preheater and the high-temperature air preheater in sequence, and is heated to 600°C before being sent into the combustion chamber;
[0046] 2) Fuel oil and additives are sent into the combustion chamber and mixed with hot air for combustion. The temperature is controlled at 1520°C. The hot smoke generated by combustion enters the reaction chamber through the throat, and the raw material oil is sprayed into the reaction chamber through the throat. Cracking reaction; the temperature is 1450°C and the pressure is 20Kpa.
[0047] 3) After the reaction, the product flue gas of the reaction is quenched by quenching water and then enters the waste heat boiler, and then passes through the high-temperature air preheater, medium-temperature air preheater and low-temperature air preheater to reduce the temperature of the product ...
Embodiment 3
[0059] 1) The air is compressed by a Roots blower to a pressure of 0.038Mpa, then passes through a low-temperature air preheater, a medium-temperature air preheater and a high-temperature air preheater in sequence, and is heated to 600°C before being sent into the combustion chamber;
[0060] 2) Fuel oil and additives are sent into the combustion chamber and mixed with hot air for combustion. The temperature is controlled at 1510°C. The hot flue gas generated by combustion enters the reaction chamber through the throat, and the raw material oil is sprayed into the reaction chamber through the throat. Cracking reaction; the temperature is 1450°C and the pressure is 20Kpa.
[0061] 3) After the reaction, the product flue gas of the reaction is quenched by quenching water and then enters the waste heat boiler, and then passes through the high-temperature air preheater, medium-temperature air preheater and low-temperature air preheater to reduce the temperature of the product flue ...
