In an integrated gasification power plant a steam recovery system is provided. The system enables power generation equipment designed for a predominant fuel and operating condition to efficiently utilize additional steam generation by syngas coolers when heat transfer surface condition or fuel characteristics enable additional steam generation. The system can detect excess steam generation, integrate it with the syngas cleaning process and transmit it to the power generation equipment. The system results in a low cost power generation system which is capable of efficiently operating with a wide range of fuels and a wide rang of operating conditions.
