Abstract
In Japan, effective utilization of waste heat from municipal solid waste incineration plants has become very important to restrain output of CO_2. 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. is developing latent thermal energy storage equipment for this transport system. This equipment is using Erythritol of phase change material (PCM) and direct contact heat transfer technology. Direct contact heat transfer technology is heat exchange method contacted heat medium to PCM. The advantages are high performances of heat input and heat output, light weight equipment by no heat exchanger. In order to estimate the performance of this system, two sets of thermal energy storage experiment, 15kg and 400kg of erythritol were carried out. As a result, stable operation of the two set systems and high performance were obtained.
