@jmyheaters: The SCR denitrification catalyst has a fixed active temperature window (280~420 ℃), and insufficient flue gas temperature under low load and start stop conditions of the boiler can directly cause a decrease in denitrification efficiency, excessive ammonia escape, and blockage of reducing agent crystallization, which is a common problem for stable and compliant environmental protection systems. The denitration air duct heater is designed to match the high air volume and atmospheric pressure flue, connected in series with the denitration pre stage air duct, to supplement the heat and temperature of the flue gas, maintain the flue gas stable in the optimal reaction temperature range of the catalyst, and ensure the continuous and efficient removal of NOx. ✅ Product Advantages Box type square flange structure, suitable for large section flue and high air volume flue gas conditions, flow field optimization, low wind resistance, and no disturbance to the original flue gas flow; The heating element can be made of 304/310S/316L stainless steel finned tube, which is resistant to dust, sulfur oxide corrosion, and suitable for long-term continuous operation; Equipped with PID+thyristor temperature control system, stable temperature control; Set multiple interlock protections for overheating, fan linkage, and low flow to prevent dry burning, which can be made into explosion-proof structures as needed; Modular heating core design, the heating core can be separately removed for maintenance and replacement, making maintenance convenient; Power, inlet and outlet size, voltage, and material can all be customized according to non-standard requirements, suitable for new denitrification projects and old unit renovations. 👉 Applicable scenarios: Garbage incinerators, biomass boilers, chemical kilns, small-scale coal-fired boilers SCR/SNCR denitration flue gas reheating. #Airductheater #denitrationairductheater #SCRdenitration #fluegaselectricheater #environmentallyfriendlyelectricheatingequipment
