    • An improved heat exchanger which resists fouling of the heat exchange surface by minimizing the temperature difference between the heat exchanger surface and the fluid stream in contact with the heat exchange surface. In one embodiment, fouling of the heat exchanger surfaces in a combustion air heat exchanger may be minimized by minimizing the temperature difference between the heat exchanger surface and the carbon black stream in contact with the heat exchanger surface. In the case of a combustion air heat exchanger, the temperature difference between the heat exchanger surfaces and the carbon black stream is preferably not greater than 500 °F, more preferably not greater than 300 °F and even more preferably not greater than 100 °F.
    • 一种改进的热交换器,其通过使热交换器表面和与热交换表面接触的流体流之间的温差最小化来抵抗热交换表面的结垢。 在一个实施例中,通过使热交换器表面和与热交换器表面接触的炭黑流之间的温差最小化,可以使燃烧空气热交换器中的热交换器表面的结垢最小化。 在燃烧空气热交换器的情况下,热交换器表面和炭黑流之间的温差优选不大于500℉,更优选不大于300℉,甚至更优选不大于100℉ 。
