Working principle of thermal oil steam generator

1, ZFQ series evaporator is the heat of the heat transfer oil in a certain heat transfer mode to the water supply, thus generating steam equipment.

2, its working principle is: indirect heating, also known as surface type. In the equipment, the cold and hot media flow continuously in their respective channels to complete the heat transfer task, do not contact each other, do not mix. It is the most widely used, the largest number of the class.

3, the evaporator usually adopts the structure of shell and tube heat exchanger, which is mainly used for heating pure water to evaporate and vaporize.

4. Its structure diagram and heat transfer system are shown as follows:

5, heat transfer oil from the bottom of the evaporator U-shaped heat exchanger into the evaporator tube, shell for water, by the feed pump to ensure the level of the evaporator. Heat transfer mode: longitudinal scouring in the tube, natural convection outside the tube, heat transfer oil after the temperature is reduced, discharged from the other end of the U-shaped heat exchanger.
