12 9 Research Activities Biomass Team Leader: Dr.Sahataya Ladpala Research: Tar Reduction in Producer Gas by a Thermosyphon Heat Pipe Heat Exchanger Sahataya Thongsan, Sukruedee Sukchai, Somchai Jiajitsawat, Bongkot Prasit and Sasithorn Lertmaneepong This research presents the simulation of a thermosyphon heat exchanger for producer gas cleaning of a gasification power generation system by decreasing temperature of the gas to tar dew point. In this project, Eucalyptus residuals are used as fuel for gas production in a fixed bed down draft gasifier. The temperature and flow rate of the gas at the gasifier outlet experimentally measured were 250C and 135 m 3 /h, respectively. A proposed heat exchanger is employed to dissipate the heat out of the hot gas till the tar dew point is reached and then condensed. This heat exchanger consists of copper-tube heat pipes filled with water at 50 % of heat pipes evaporator. Each heat pipe has 100 cm in length, 2.23 cm in diameter, and cm in internal diameter. The heat exchanger performance was simulated and optimized by varying the number of heat pipes. Figure 1: Thermosyphon Figure 2: Thermosyphon heat exchanger The result from the simulation was shown that 205 heat pipes calculated can reduce the temperature of producer gas to the tar dew point. An experimental validation of the system performance is in progress. Figure 3: Picture of the System

13 10 Energy Community Team Leader: Dr.Pisit Maneechot Research: Technology Transfer of A Jar-Biogas Digester to Community: KlongKoo Village, Tha-pho District, Phitsanulok Pisit Maneechot, Prapita Thanarak and Wikarn Wansungnern The Energy for Community research unit, School of Renewable Energy Technology, Naresuan University, developed a jar-typed biogas digester for cooking gas production to substitute the LPG in order to help people independent from its increasing prices. The developed digester was successful in operation, practical, and worth in investment. This concept of technology transfer to the community is consistent with one of the school missions. The objectives of this project are: 1) to transfer knowledge of a jar-typed biogas digester technology to the community for applying in their daily life and to correctly and effectively transfer to other communities and 2) to be used as an approach in development and promotion of technology usage widely and continuously. A family of Mr. Boomee Comemon, 41 year-old with 4 members, inhabiting at 8/1 Moo 4 Tamboo Tapho, Amphoe-Muang, Phitsanulok, 65000, was chosen as a representative family for the experimental testing of the developed biogas digester. The result of this study presents that LPG consumption of the household is about 315 Baht per month. The average biogas quantity is m 3 per day while adding animal waste 1-2 kg per day. This amount is appropriate to household of 3-4 members and total expense saving is 3,780 Baht per year. If the investment cost is 6,611 Baht (exclude labor cost), the simple payback period calculated is 1 year and 9 months. Increasing LPG market price will cause payback period shorter. Biogas production from 1,900 liters of animal and household waste with 120 liters storage tank is suitable for 3-4 members. This household should have 3-4 pigs and have mediumunderstanding on biogas production. The biogas technology transfer should be simple and effective to promote to the community. There are community energy volunteers that may help to distribute their skill and knowledge to the village members. Hence, all these factors will make the technology transfer successful and sustainable.

14 11 Research: Economic analysis of CO 2 emission reduction from large scale photovoltaic power plant in Thailand This research presents the study on carbon dioxide emission reduction from large scale photovoltaic (PV) power plant in Thailand using a method based on Annex 14 Methodological Tool (Version 02) Tool to calculate the emission factor for an electricity system. The calculation result is coefficient of green house gas emission factor (Combined Margin Emission Factor) for solar electricity generation is tco 2 /MWh. Besides that the study on economic analysis of large scale PV power plant in Thailand, with interest rate at 6.75%, benefit from selling CO 2 in 7 years shows that net present value (NPV) is 2,472,187,645 Baht, benefit cost ratio (BCR) at 12.52, economic internal rate of return (EIRR) is 20.01%, cost of energy (COE) is 7.96 Baht/ kwh and payback period less than 5 years. The sensitivity analysis also presented in this research. Considering the degradable PV efficiency and initial cost have positive economic indicator results. However, adder cost at 6.5 Baht/kWh and interest rate at 10% and 15% make negative economic indicator results. Also considering the different of energy yield at 1,400kWh/ kwp found that internal rate of return is 6.66% which is less than interest rate at Thus, all PV entrepreneurs are agreeing for bright and growing future of PV industrial business in Thailand. Research: Supply chain management of agricultural waste for biomass utilization and CO 2 emission reduction in the lower northern region of Thailand Thailand Government has a policy to promote the production of renewable energy and it imposes the way for supporting another production of renewable energy by Ministry of Energy. It imposes the goal of using a renewable energy for producing electricity in 2022 is 3,700 MW. However, the supporting of using biomass in industrials still have problems in management of using fuel, which spread in the area efficiently, it affects in situation of fuel purchase, high transportation, and the cost of electricity from biomass. So it has to consider the benefit of environment in producing of electricity from biomass. The way of reducing Carbon dioxide emission is a process of Clean Development Mechanism (CDM). It is a choice to do in this project. In Thailand, there is project CDM about % and,it has a certification of Letter of Approval (LoA) about 160 projects. The research aims to study of reducing of Carbon dioxide from production of electricity energy from biomass for a small community power plants by using the information of agricultural products in from survey in 9 the Lower Northern region of Thailand such as Kamphaeng Phet, Tak, Nakhon Sawan, Sukhothai, Phichit, Phitsanulok, Phetchabun, Uttaradit, and Uthai Thani that have agricultural waste such as rice husk, corncob, bagasse, and Cassava rhizome. There are 7,608,080 tons per year which calculate the potential to establish a small community power plant is MW. According to the amount of leaving Carbon dioxide of Annex 12 Methodological tool (Version 01.1) Tool to calculate the emission factor for an electricity system found that the potential was reduced Carbon dioxide about 1,000,269-2,000,592 corbon dioxide tons per year. The amount of each type of agricultural waste; rice husk, corn cob, bagasse and cassava rhizome, from survey and interview, are no correlation with the planting area or provinces or planting year. From economic analysis in rate of the project size is 1.2 MW, it reduces about 7 %, Net Present Value is 161,539,087 Baht, Benefit-Cost Ratio (BCR) is 1.85, and Internal Rate of Return (IRR) is 21%. Payback period is 8.86 years, besides that, Cost of Energy (COE) is 5.73 Baht. It indicates that the project will have a profit for be worth to invest which is a profit for investment, and it can be manage. For the sensitivity analysis for evaluating of compensation after changing the factor which effect to produce electricity such as amount of fuel and cost of fuel which change to 10 P.C. and analyze a sensitive of the project causes technician problems in power plants. So it was stopped to run a machine. From the study of all cases show that the project has IRR more that rate of reducing and NPV increase. According to Net Present Value, the cash inflow more than cash outflow, moreover, the ratio between the interest of project and the total of investment calculate from Net Present Value or Benefit-Cost Ratio more than 1. Therefore, this study show that although the project will effect from changing in capital investment and beneficial, the project of community of power plants from biomass size is 1.2 MW have a profit for investment and compensation for investment which can be run to continue the project.
