Compact Heat Exchanger
INTRODUCTION Heat exchanger is a apparatus that has two streams of fluid that exchange temperatures in order to heat or cool the system. Basically this Blog focuses on what are compact heat exchangers, the various types, costs, advantages and disadvantages and how fouling may affect. Area density greater than 700 m²/m³ for gas or greater than 300 m²/m³ when operating in liquid or two-phase streams. TYPES OF CHE’S Plane and Frame Heat Exchanger :-(PHE) Most common type of PHE Consists of plates and gaskets Materials: stainless steel, titanium and non-metallic Operation limits:- temperatures from -35°C to 220°C pressures up to 25 bar -flow rate up to 5000 m³/h Brazed Plate Heat Exchanger :-(PHE) Operates at higher pressures than gasketed units Materials: stainless steel, copper contained braze Operating limits: From-195 C to 200°C Pressures up to 30 bar Welded Plate Heat Exchanger Plates welded together to increase pressure and temperatur
