Waste heat recovery apparatus.

摘要

A waste heat recovery apparatus is disclosed which recovers the waste heat of high temperature exhaust gas discharged from a furnace (1). The apparatus includes a radiation body (9) made of ceramic material, which is formed with a ehat radiation surface arranged in the vicinity of, and toward the inside of the furnace (1). The radiation body (9) has a plurality of regular channels (8) allowing passage of the exhause gas therethrough. Exhaust gas passed through the channels (8) heats the radiation body (9), and substantial amount of the holding heat of the exhaust gas is radiated from the radiation surface toward the inside of the furnace (1), allowing an efficient waste heat recove y.
