Gasification and power generation from solid wastes using high temperature air steam (2nd report: R D on high temperature heat exchanger)

摘要

Tests of high temperature heat exchanger are performed to demonstrate high temperature air and steam heating. The effectiveness is over 90% without steam heating at 900°C of combustion gas. When the flow rate of steam is increased, the effectiveness decreases. From combustion gas of 900°C, air and steam mixture of 700°C is obtained.
