How to use a KH-type nozzle?
Thread Content
What are the technical specifications and usage methods of KH-type nozzles? What are the specific pressure drops and steam consumption levels? Also, what is the optimal pressure before the nozzle? Please, experts, give me some advice!
The kH nozzle supplier should provide these data as well!
Generally, it is the design manufacturer who provides the data; when fluid dynamics are involved, the manufacturer specifies the range of steam consumption, steam pressure, the minimum pressure before the feed nozzle, flow rate, and so on.
Pressure drop of 0.3 to 0.4 MPa； The steam proportion should be between 3 and 5%; the heavier the raw material, the higher the atomization ratio. A certain degree of superheat is necessary, and the temperature of the low-pressure steam should not be lower than 250 degrees. In particular, it must not be lower than the preheating temperature of the raw material, otherwise the increased viscosity of the raw material will affect the atomization effect ； The low-pressure steam in front of the nozzle should not be lower than 0.75 MPa ； The preheating temperature of the crude oil must be kept below 5 degrees Celsius.
