The fouling prevention and on line cleaning of desiliconization preheating exchanger with the fluidized inert solid particles is investigated.

Effects of ultrasonic wave on the surface properties of solid particle;

Investigation on boiling heat transfer enhancement and anti-scaling process by using solid particles;

Through studying the reasons that solid particle erosion is generated in supercritical turbine during manufacture and operation, take measures by optimization and spray harden in flowing part and flexible application of by-pass system, avoiding to happen solid grain corroding phenomenon effectively.

Incipient motion of solid grain in solid-liquid two\|phase flow is often concerned in many petroleum technologies, such as horizontal drilling, gravel-packing and sand washing.
