| Abstract | This study is focused on introducing a trigeneration system at AIT, which is similar to one installed at related Suvarnabhumi Airport, and also estimate Greenhouse Gas (GHG) emission and mitigation potential. District Cooling System and Power Plant company produces and supply power and cooling to the airport by using natural gas as a fuel. The system operates with two gas turbines and one steam turbine for power supply and absorption chiller system. The electrical capacity of power plant is 50 MW and the cooling capacity is 13,500 RT. The efficiency of cogeneration system and Coefficient of Performance is 50% and 1.2,respectively. The GHG emission from power plant is 13,222 ton of CO2 equivalent per year. Two cases are proposed for Asian Institute of Technology. Case I is using a similar Trigeneration system available at Suvarnabhumi Airport using related gas as fuel. Case II is a dual fuel fired Trigeneration system using producer gas from gasification plant and natural gas as fuels. The electrical capacity and cooling capacity at AIT are 1.2 MW and, 950 RT. The electrical efficiency, overall efficiency, and Coefficient of Performance of the proposed system is 35%, 85%, and 1.2, respectively. For the proposed system, the total power output and the cooling loads from both cases are 2.5 MW and 1,200 RT respectively. The payback period from case I and II is 5.99, and 5.97 years, respectively. The GHG emission reduction from case II, i.e. after using biomass, is around 38 ton CO2 per year. |
