Duct heater exposed

The key locations where the exposure appears are the seal between the plate and the plate, the position of the two leak seal grooves of the plate and the top of the plate and the inside of the clamping plate. Then talk about the large pressure drop, and the pressure drop of the material inlet and outlet exceeds the design plan, or even many times higher than the value of the design plan, which seriously jeopardizes the total flow and temperature of the system. In the heating system, if the thermal pressure drop is too large, the total flow on the primary side will be lacking, that is, the pyrogen is insufficient, resulting in the secondary side outlet temperature can not meet the requirements.
