Energy Recovery from Waste Fuel Waste LNG Coal Diesel LCV (kcal) 2,632 9,550 5,950 8,450 EQ, Energy 4ton 1.1Nm 3 1.8ton 1.2ton By incinerating of 1ton of waste, 2MWh district heating and 0.67MWh electricity can be produced. According to the statistics of Korean Environmental Agency, the calorific value of waste in 2008 is 2,632kcal/kg on average. Therefore, 4tons of waste substitutes 1.2ton of Diesel or 1.8 ton of Coal. 6

10 03. Comparison of Technologies Below is preliminary comparison of Stocker type incineration and MBT + RDF fueled power plants based on the assumption of 1,000TPD fresh waste. Please note that the figures herein are just reference only for the purpose of comparison of both technologies. Classification Incinerator MBT + RDF Power Plant Plant Capacity Assumed Residue of Waste To be landfilled Construction Area Budgetary CAPEX (CAPEX/Ton) Incineration Facility: 1,000 TPD Bottom ash and fly ash: 110 TPD 12,000m2 (80m X 150m) Incinerator : USD 150,000 ~ 200,000/ton Fresh Waste1,000 TPD RDF 500 TPD Incombustible : 240TPD 32,400 m3 -Power GenerationPlant : 50m X 150m -RDF processing plant : 120m X 220m MBT Facility : USD 110,000 ~ 150,000/ton Power Generation Plant : USD 200,000 ~ 250,000/ton Total : USD 210,000 ~ 275,000/ton OPEX (Exclusion from Operating Benefit) Incinerator: USD 30 ~ 40/ton MBT : USD 15 ~ 25/ton Power Generation: USD 40 ~ 50/ton Total : USD 35 ~ 50/ton 10

Comparison of Technologies Classification Incinerator MBT + RDF Power Plant Expected Power Generation Self-Consumption Possible Sale of Electric Power 3.5MWH from Incineration Facility 1,000 TPD 23.5MW 2.0 MW for Power Generation Facility 500 TPD 5.0 MW for MBT Facility1,000 TPD Total: 7.0MW 14.0MW Necessary Operation Manpower 38 people 48 people Construction Period Operating Plants in Korea 30 Months (Including Commissioning Period for 3 Months) In Korea, more than 50 waste incineration plants are being operated (only for 50TPD or over capacity) 30Months (Including Commissioning Period for 3 Months) A 200 TPD MBT plant is under trial-running at SudokwonLandfill site. 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

12 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

15 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

16 03. Waste Treatment Status Ratio of recycling and incineration being increased while landfilling being decreased. In 2010, 60.5% by recycling, 21.6% by Incineration, 17.9% by Landfill against 56.6%, 17.0%, and 25.8% respectively in 2006 (based on MSW) MSW : Recycling/Incineration Landfill - 06(%) Recycling 56.6, Incineration 17.0, Landfill (%) Recycling 60.5, Incineration 21.6, Landfill 17.9 Industrial Waste : Recycling Incineration / Disposal to Sea - 06(%) Recycling 59.4, Incineration 7.6, Landfill 23.3, Disposal (%) Recycling 72.3, Incineration 5.8, Landfill 16.9, Disposal

Technical Collaboration with B&W Volund, Denmark L90, Esbjerg, Denmark, 2003 (1x576 TPD) Babcock & Wilcox Volund(BWV) in Denmark is one of the world`s leading suppliers of equipment and technologies designed to convert household wastes and bio-fuels into thermal energy With 80 years of experience, BWV has offered solutions for Waste-to-Energy systems & Biomass Energy systems all over the world in technical tie-up with BWV since 1991 has made remarkable achievements in the field of waste to energy plants. 24

25 05. General Process of Halla Waste to Energy Plant 25

26 06. General Layout of Waste to Energy Plant Crane Incinerator & Boiler Fluegas Treatment Waste Storage Bunker Turbine Generator 26

27 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

28 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

29 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
