Reasons for High Air Preheater Exhaust Temperature
Reasons for High Air Preheater Exhaust Temperature Reasons for High Air Preheater Exhaust Temperature Because the exhaust temperature of air preheaters in power plant boilers is generally high, this high exhaust temperature reduces boiler efficiency, resulting in insufficient drying output in the pulverizing system, making long-term operation very uneconomical. This is a common problem [...]
What is Air Finned Cooler?
What is Air Finned Cooler? An air finned cooler (also known as an air cooler or air cooled heat exchanger) uses ambient air as the cooling medium, performing forced convection heat transfer through finned tubes. Its core structure consists of a tube bundle, bracket, fan, and finned tubes (typically aluminum fins for enhanced heat transfer). [...]
What are Extruded Aluminum Fins?
What are Extruded Aluminum Fins? Extruded aluminum fins are heat dissipation components made by tightly attaching aluminum to a base tube (such as a steel or copper tube) through an extrusion process. They offer high heat transfer efficiency and structural stability. Extruded aluminum fins are heat dissipation components manufactured through aluminum extrusion and are widely [...]
