1. Development of Drum Dryer System with Superheated Steam
The purpose of this research is developing the drum dryer with superheated steam to increase the efficiency of the conventional cylinder drum dryer used in the dry process of the paper industry. Optimization, development for applied technology, superheated steam generator will be performed and localization of component will be realized. Finally, reliability will be obtained through some experiment and the developed system will be commercialized.
The purpose of first step of this research is developing the drum dryer with superheated steam with the capacity of dealing with 70% water-contented product by 200kg/hr. And the efficiency of this system is better than dryer with heated air by 20%. The main contents for success of this project are developing the method for improving efficiency, analyzing the characteristics of drying by superheated steam, analyzing energy-saving effect by recycling superheated steam, improving optimization skill through design and manufacturing pilot dryer, evaluating the feasibility for mingling drum dryer with impingement dryer, developing the real 200kg/hr drum dryer with superheated dryer and test for characteristics.
2. Development of Superheated Steam Generator with Low Pressure and High Superheated Temperature
This project intends to develop a low pressure high temperature superheated steam generator for drying as its core technology by further heating in a superheater the saturated steam produced in an existing boiler. Therefore, the purpose of the project is to develop a low pressure high temperature superheated steam generator with a generation capacity of 200kg/hr of superheated steam at $400^{\circ}C$ and $1kg/cm^2$ with an efficiency of 83%.
3. Development on Rotary Dryer with Multi Stage Drum and the Recirculation of Exhaust Gas of High Temperature and Humidity
The final purpose of development is to develop the high efficient rotary dryer with multi-stage drum by the recirculation of exhaust gas of high temperature and humidity. In the first year, the purpose of research was to develop the design technology of rotary dryer by the recirculation of exhaust gas with high temperature and humidity. The purpose in the second year is to develop the design and manufacture technology of the rotary dryer with multi-stage drum and the recirculation of exhaust gas of high temperature and humidity for commercial model.
The detailed contents and scope in the first year are as follows; experiment of sludge movement by velocity of air in the horizontal state of drum, analysis method of drying process by the recirculation of exhaust gas for the optimum design of rotary dryer, design method of rotary dryer, and performance test and design of prototype of rotary dryer with multi-stage drum for design data deduction, which drying capacity is 100 kg/hr. In the second year, performance prediction and analysis by simulation program, design and manufacture of prototype of rotary dryer with multi-stage drum and recirculation of exhaust gas, which drying capacity is 300 kg/hr, were developed.
