A method of reducing the temperature of hot combustion gases discharging from atop a ship stack and at least partially suppressing infrared radiation thereof by the steps of preheating water to near 100 DEG C. and spraying it into the hot gases at near the base of the stack. Hot water is used because it more readily vaporizes and absorbs the latent heat of vaporization from the gases and exits the stack as a vapor, the radiation from which is more readily absorbed by water vapor, always present above the sea, than is radiation from water droplets.
