The newly installed desulfurization and denitrification fans have a suction pressure of 800 Pa, but the main flue gas duct has a pressure of around 480 Pa, while the branch flue gas ducts have a pressure of around 250 Pa. What is the problem?
Brother, can you express your question in professional terms? In the case of desulfurization and denitrification in power plants, a booster fan is generally installed in front of the desulfurization tower; this fan is used to overcome the resistance in the flue gas ducts and the desulfurization tower itself. Power plant chimneys are all over a hundred meters tall, giving them strong self-levitation capacity; in other words, there is negative pressure at the entrance of the chimney. Typically, desulfurization booster fans in power plants are not allowed to use the chimney’s self-priming effect; in other words, when the desulfurization unit is shut down, it does not affect the normal operation of the power plant.
