Wonju(80 TPD), Bucheon(90 TPD) and a few other plants are being operated. Some other plants in Pohang, Busan, Daegu, and Gwangju, etc. are being planned but being delayed. 11
03. Comparison of Technologies Classification Incinerator MBT + RDF Power Plant Advantages - Continuous treatment is possible even with some uneven qualities of fresh waste. - Extension of landfill site s lifetime (twice of MBT facility and so reduction of land consumption for landfill - Most reliable and stable technology proven through the most popular installations - Lower consumption of electric power for operation than RDF power plant - Less O&M manpower than RDF power plant - Higher quality of fuel can be obtained. - Easier transportation of RDF fuel generated to other sites for fueling. Disadvantages - Higher Exhaust Gases may be occurred. - The Stability of Boiler for Generating Steam is weaker than that of RDF Boiler. - Considerably larger land space for plant construction (approximately by 3 times of incineration Plant.) needed. - Large space of landfill site shall be maintained which in the long run will be a severe burdensome. - Lower Energy Efficiency than incineration plant - Higher Manpower and Cost for O & M 12

02. Waste Generation Status Growth rate of MSW generation has been slowed due to Government s policy to reduce the MSW Production such as Volume Based Waste Fee System and Restriction on Disposable Products. But industrial and construction wastes have been constantly increasing with the expanding business and economy of the country. 15

06. General Layout of Waste to Energy Plant Crane Incinerator & Boiler Fluegas Treatment Waste Storage Bunker Turbine Generator 26
07. Grate Systems for Incinerator HallaIncinerator is suitable to burn waste continuously with - High combustion efficiency - Minimum emission of harmful substances - And Maximum energy recovery The component part of the grate is of a rigid design developed for heavy-duty and high temperature operation. Grate bar Grate is divided with dry & ignition grate, combustion grate and burn-out grate. Grate block 27
08. Boiler HallaBoiler is built as a standing boiler. This makes the design more advantageous and facilitates the erection. The Boiler is a drum boiler with natural circulation. Equal temperature of the walls all over in the pressure parts gives minimum thermal strains, so it is possible to use minimum wall thickness 28
09. Computational Fluid Dynamics (CFD) Program In order to achieve the best possible design of the system, Hallauses Computational Fluid Dynamics CFD programs as a tool for detailed engineering. CFD gives the designer the possibility of checking the design for a large number of critical factors such as velocities, particle impingement, oxygen concentration, temperature, surface temperature, corrosion etc. The client will receive a plant with a larger life expectancy and a more reliable operation Gas Flow Temperature CO Particle Path 29
