description PURPOSE: To cool a reformed gas and an exhaust air so as to keep optimum temperature, working as safety protection when a heat exchanger for exhaust heat recovery using as a heat source of heating-cooling equipment stops and without being affected by heat load variation in an exhaust heat utilizing line in a fuel cell power generating system adopting cogeneration. CONSTITUTION: Heat exchangers 6, 10 for exhaust heat recovery for using as a heat source of exhaust heat utilizing equipment are installed in the front steps of a reformed gas cooling device 7 and an exhaust air cooling device 11 in a reformed gas supply line 3 and an exhaust air line 4. Bypass paths 6a, 10a for bypassing the whole amounts of reformed gas and exhaust air when the operation of the exhaust heat utilizing equipment is stopped and gas shut off valves 6b-6d, 10b-10d are arranged in the heat exchangers for exhaust heat recovery. Flow rate control valves 7a, 11a of cooling water and temperature controllers 7b, 11b are installed in the reformed gas cooling device and the exhaust air cooling device to cool the reformed gas and the exhaust air to a constant temperature, and to condense and separate steam.
