Specification

Functions

This type of economizer can largely develop the heat exchanging area than the bare economizer to add the heat transfer area, reduce the volume, compact structure and reduce the number of elbow and welding to make less leakage and add the heat transfer efficiency.
Not easy to collect dust and the fume pass through the fin tube to form the boundary layer to occur the vortex to make less chance for the fly ash particle to touch the tube wall.
Widely temperature range, high pressure limit.
