| Abstract: | With the increase of unit volume, the design parameter of HP increases as well. As a result, the design of traditional U-tube type HP becomes more and more difficult. Meanwhile, snake-tube type HP with better thermo elasticity and low failure rate can meet the requirement of the high-demand parameter of current auxiliaries. The promotion of snake-tube type heater in large-scale units will make heaters more reliable, which provides a new design method. |
