Design and application on the new type phase change heater

The phase changed heater has been applied widely in gas-oil transportation engineering,it has played important role on reducing energy consumption,but the figure structure and metal consumption have not improved virtually.Based on above questions,the design idea of shell boiler has been applied to improve and design the heater's structure. The paper describes the working principle of phase changed heater and introduces this new type heater on the design idea,characteristic and engineering application.
