การออกแบบระบบผลิตไฟฟ้าด้วยเทอร์โมอิเล็กตริกผลิตไฟฟ้าโดยใช้ความร้อนทิ้งจากห้องเผาไหม้ชีวมวล

Abstract

This paper investigate the thermoelectric power generation from combustion wall of biomass drier. In this study, three modules of thermoelectric were considered: two thermoelectric cooling modules (Model A : MT2-1,6-127 andModel B : TEC1- 12708) and one thermoelectric power generation module (Model C : TEP1-1264-3.4) respectively. Testing results show that thermoelectric TEC1-12708can generate maximium power output 1.5 W/module (2.52 V, 0.59 A) the second one is TEP1-1264- 3.4can generate power output 1.07 W/module (2.13 V, 0.50 A) and MT2-1,6-127can generate least power output 0.87 W/module (2.18 V, 0.40 A) ,so the suitable thermoelectric cooling TEC1-12708 is appropriate to apply for thermoelectric power generation system. The experimentations were used 4 pieces of 6 W (3,500 RPM, 2.50 m3/s) ventilation fan and 12 thermoelectric modules to used in the system, which installed at backside of the burner box.
