Abstract
Effective utilization of waste heat from municipal solid waste incineration plants and biomass power plants has become very important to reduce CO_2 emissions. But it is difficult to use waste heat on site or very near by. Because waste heat from municipal solid waste incineration plants is too many value to use for heating and cooling applications on site. We need the method to transport waste heat to heating and cooling applications of other site. Kobe Steel Ltd. and Kobelco Eco-Solutions Co., Ltd are developing latent thermal energy storage equipment for this transport system. The erythritol of phase change material (PCM) and direct contact heat transfer technology are being used for this equipment. Direct contact heat transfer technology is thermal energy storage method of contacting heat medium to PCM directly. The advantages are high performances of heat input and heat output, light weight equipment by no heat exchanger. This time, in order to study the applicability as a heat source to the absorption refrigerator of this system, the experiment which used thermal energy storage cassette and absorption refrigerator was carried out. As a result, stable operation of this system and the effect of fuel consumption reduction were obtained.
