High Performance Plate Heat Exchanger for Boiler Blowdown Heat Recovery
Introduction
Plate heat exchanger is a high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, long service life and so on. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, the floor space is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90%.

How It Works
As a new efficient and compact heat exchanger, this product consists of multiple parallel corrugated-surface thin metal sheets that overlap and are then fixed by lamp plates and bolts.
Heat exchange principle: the cold working fluid and the hot working fluid flow through the narrow and winding passage made of two neighboring plates alternately and realize cold and heat exchange through the plates separating the two working fluids.
Plates and Gaskets
The plate heat exchanger's plate materials and corresponding applicable places are given in Table 1 and its gasket materials and corresponding applicable places in Table 2 for your reference.
