Abstract
If the waste heat recovery and its utilization is realized, we can raise the thermal environment in urban area. It is said that utilization of waste heat of Refuse Incinerating Plant (R. I. P.) is good chance of realization. Though R. I. P. is large source of heat exhaust, it is diffcult to estimate the quantity of heat exhaust. As the heat source of R. I. P. is refuse, we can't infer the heat quantity from the quantity of energy consumption. In this report we put an investigation into R. I. P. in the whole country, and analize the result statistically. In the result we found the index of heat exhaust, heat recovery, heat utilization (possibility) in the form of Q=aR (Q : quantity of heat <Gcal>, R : quantity of refuse incinerating <t>, a : constant). Main indexes of heat are as follows. 1. Q_e=1.529R (Q_e : quantity of heat exhaust) 2. Q_r=0.981R (Q_r : quantity of heat recovery) 3. Q_u=0.787R (Q_u : quantity of heat utilization) In this case R. I. P. haven't independent power system that use the waste heat. We compare the quantity of heat recovery used of the index with the practice measurement value based on the investigation. In this study the coeffcient of correlation came to 0.9540, we found that we could use the index in a high rate of preciseness.
