Annual output of 120000 tons of kerosene cooler’s design
Abstract：Over the past 25 years, the important of heat exchanger is increasing fast in the field of energy saving, energy conversion, energy recovery, and new energy. At the same time, this increasing importance is also related to the issues that people pay attention to, such as thermal pollution, air pollution, water pollution and waste disposal, etc. Heat exchanger is widely used in processing, power, transportation, air conditioning, refrigeration and low temperature, heat recovery, alternative fuels, and in the field of manufacturing, and is also a key part of many industrial products on the market. Thus, the reasonable design of heat exchanger and a good runs for enterprises to save money, energy and space is very important. In today's condition of increasingly shortage of energy, improve heat transfer performance and reduce its volume of heat exchanger is more obvious economic and social benefits.
This article according to the title of kerosene cooler to take a rational selection and make design. Content includes heat exchanger type selection, thermodynamic calculation, structural design, intensity, etc., the design of a variety of qualitative and quantitative factors, and their mutual influence and mutual dependency are discussed ,so that to optimizing the heat exchanger design.
Key words：Heat exchanger; Kerosene cooler; Fixed tube plate; Thermodynamic calculation
