PROBLEM TO BE SOLVED: To equalize quantity of heat absorbed by each heater by locating four heaters at the upstream and downstream of hot gas by half respectively and equalizing heat transfer amount to the two heaters on the downstream side and heat transfer amount of two heaters on the upstream side by providing a balancing means. SOLUTION: Because conversion efficiency is lowered when a difference is generated between works performed by working medium flowing in heaters, a balancing means is provided for equalizing a temperature of working medium flowing within a heater 15A on an upstream side and a temperature of working medium flowing within a heater 15B on a downstream side. In this conversion means, a heater tube of the heater 15B on the downstream side is provided with a fin 21, and area where the heater 15B on the downstream side is exposed to hot gas and area where the heater 15A on the upstream side is exposed to hot gas are increased by fixed amount as a whole. As a result, quantity of heat that each heater absorbs is equalized and output lowering of an engine is prevented.
