  "text": "Technique\nDescription\nApplicability\na.\nHeat recovery from the gasification process\nAs the syngas needs to be cooled down to be cleaned further, energy can be recovered for producing additional steam to be added to the steam turbine cycle, enabling additional electrical power to be produced\nOnly applicable to IGCC units and to gasification units directly associated to boilers with syngas pretreatment that requires cooling down of the syngas\nb.\nIntegration of gasification and combustion processes\nThe unit can be designed with full integration of the air supply unit (ASU) and the gas turbine, with all the air fed to the ASU being supplied (extracted) from the gas turbine compressor\nThe applicability is limited to IGCC units by the flexibility needs of the integrated plant to quickly provide the grid with electricity when renewable power plants are not available\nc.\nDry feedstock feeding system\nUse of a dry system for feeding the fuel to the gasifier, in order to improve the energy efficiency of the gasification process\nOnly applicable to new units\nd.\nHigh-temperature and -pressure gasification\nUse of gasification technique with high-temperature and -pressure operating parameters, in order to maximise the efficiency of energy conversion\nOnly applicable to new units\ne.\nDesign improvements\nDesign improvements, such as:\nmodifications of the gasifier refractory and/or cooling system,\ninstallation of an expander to recover energy from the syngas pressure drop before combustion\nGenerally applicable to IGCC units\nTable 42\nBAT-associated energy efficiency levels (BAT-AEELs) for gasification and IGCC units\nType of combustion unit configuration\nBAT-AEELs\nNet electrical efficiency (%) of an IGCC unit\nNet total fuel utilisation (%) of a new or existing gasification unit\nNew unit\nExisting unit\nGasification unit directly associated to a boiler without prior syngas treatment\nNo BAT-AEEL\n> 98\nGasification unit directly associated to a boiler with prior syngas treatment\nNo BAT-AEEL\n> 91\nIGCC unit\nNo BAT-AEEL\n34–46\n> 91",
