Abstract
Methods and apparatus for generating a vapor to be injected into a flue gas stream are described. The apparatus includes a fluid vaporization and injection assembly including an input for receiving a non-flue gas, e.g., clean, fluid heat transfer medium, e.g., air; a first sealed coil having an input and an output through which a fluid, such as ammonia, to be vaporized is passed; and a second sealed coil having an input and an output through which a heated second fluid, such as water or steam, is passed. The second sealed coil is arranged to transfer heat from the heated second fluid to the non-flue gas fluid heat transfer medium. The first sealed coil is arranged to absorb heat from the non-flue gas fluid heat transfer medium. An injection unit is coupled to an output of the first sealed coil for injecting the vaporized fluid into a flue gas stream.
