Chapter v exchange heat equipment directory 1 3 Type and application of heat transfer equipment 2, 4 Shell and tube heat exchanger The use and maintenance of heat transfer equipment for other types of heat exchanger equipment Section 1 type and application of heat exchange equipment 1. Define the application of heat transfer equipment The equipment that enables the heat transfer process is called heat transfer equipment. The equipment that enables the heat transfer process is called heat transfer equipment. Ii. Type of heat transfer equipment According to use classification Cooler condenser heat reboiler heater heat exchanger (or heat) steam generator heat or waste heat boiler in pieces according to heat transfer methods of classification The direct contact heat exchanger Regenerative heat exchanger recuperative heat exchanger 3. Comparison and selection of heat transfer equipment The basic requirements of heat exchanger Heat can effectively transfer from one fluid to another, namely heat transfer from one fluid to another. The heat efficiency is high, the unit heat transfer surface can deliver more heat. The heat efficiency is high, the unit heat transfer surface can deliver more heat. The structure of the heat exchanger can adapt to the prescribed process conditions, and the structure of the operating heat exchanger can adapt to the conditions of process operating conditions stipulated in the process. Safety and reliability, good sealing, convenient cleaning, easy maintenance and small fluid resistance. Safety and reliability, good sealing, convenient cleaning, easy maintenance and small fluid resistance. The price is cheap, the maintenance is easy, the use time is long. Cheap, easy to mainta
