Abstract
Effective utilization of waste heat from biomass power plants has become very important to reduce CO_2 emissions. However, it is difficult to use waste heat on site or very near by. This is so that there is too much waste heat to use as heating and cooling applications on the site. We need a method to transport waste heat to heating and cooling applications of other sites. 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 a thermal energy storage method of contacting heat medium to PCM directly. The advantages are high performances of heat input and heat output and light weight equipment without heat exchanger. Therefore, in this paper, we report on a study of a new model of thermal storage cassette, for the target performance of maintaining fixed heat output at a temperature of 90℃ for 8 hours, and performing 90% or more of heat recovery.
