To prevent damage to the damper door caused by flue gas condensation, the outlet temperature of the sealing fan is required to reach a certain level, necessitating an electric heater to heat the sealing air. The flue gas desulfurization system damper seal wind electric heater designed by our company can reduce production costs and improve economic benefits.
The flue gas desulfurization system damper seal wind electric heater is mainly used for air heating in the flue gas desulfurization system damper seal wind electric heater. It is available in three specifications: low temperature, medium temperature, and high temperature. Structurally, they all use steel plates to support the electric heating tubes to reduce vibration. The junction boxes are equipped with over-temperature control devices. In addition to over-temperature protection, a linkage device must be installed between the fan and the heater to ensure that the electric heater starts only after the fan starts. A differential pressure device is added before and after the heater to prevent fan failure. The pressure of the gas heated by the duct heater should generally not exceed 0.3Kg/cm2. If the pressure exceeds the above specification, please choose a circulating electric heater. The maximum gas heating temperature for low-temperature heaters does not exceed 160°C; for medium-temperature, it does not exceed 260°C; for high-temperature, it does not exceed 500°C.
The flue gas desulfurization system damper seal wind electric heater is mainly used to heat the required airflow from the initial temperature to the desired air temperature, with a maximum of 850°C. It has been widely applied in aerospace, weapon industry, chemical industry, and many scientific research and production laboratories in universities. It is particularly suitable for automatic temperature control and large-flow high-temperature combined systems and accessory tests. The air electric heater has a wide range of applications: it can heat any gas, producing hot air that is dry, moisture-free, non-conductive, non-combustible, non-explosive, non-corrosive, pollution-free, safe and reliable, and the heated space warms up quickly (controllable).
