摘要:
In various aspects, systems and methods are provided for integrating molten carbonate fuel cells with a fired heater for production of electrical power while also reducing or minimizing the amount of CO2 present in the flue gas generated by the fired heater. The molten carbonate fuel cells can be integrated for use with fired heater so that at least a portion of the flue gas from fired heater flows through cathodes of the fuel cells and at least a portion of the cathode exhaust is returned to a convection section of the fired heater.

The present invention is a method of optimizing radiant and thermal efficiency of a gas fired radiant tube heater (100). A heat exchange blower (108) receives intake air and delivers intake air through a heat exchanger (132) as pre-heated air to a combustion air blower (110). The combustion air blower receives pre-heated intake air from the heat exchanger and then provides the pre-heated intake air to a burner (120) for mixing with fuel. The fuel-intake air mixture is burned in the burner thereby producing combustion gasses which are fired into a radiant tube (118). The exhaust combustion gases pass through the balance of the radiant tube and through the heat exchanger where residual heat is transferred and extracted from the combustion gases to pre-heat the intake air. The turbulators (160) are configured to increase the turbulence within the radiant tube and are placed within the initial 3m (10') to 9 m (30') of the radiant tube after the burner to increase the tube temperature and the radiation emitted from this section of the radiant tube.
