2.6.2 空气管道 空气管道分为冷空气管道和热烟气管道两种。 冷空气

2.6.2 Air ducts <br>Air ducts are divided into two types: cold air ducts and hot flue gas ducts. <br>The cold air duct is the channel through which the blower provides combustion support to the burner and provides the oxygen required for combustion; the <br>hot flue gas duct is the channel through which the flue gas in the furnace is forcefully discharged through the induced draft fan, and is used to discharge the flue gas after heat storage and cooling. <br>The air pipeline is equipped with a pressure monitoring and regulating device as needed (subject to the actual quotation) to monitor or regulate the wind pressure. The end of the branch pipe on the furnace side is equipped with an explosion-proof membrane (with safety net), which complies with relevant safety regulations. <br>The air pipe in front of the burner is equipped with heat-resistant steel expansion joints to buffer the thermal deformation of the pipe, as well as pneumatic pulse valves, reversing valves, manual adjustment butterfly valves, etc. to control the air and flue gas volumes. It has both automatic switching and manual intervention. Realize the control and adjustment of air supply and smoke exhaust volume. The valve bodies of pulse and reversing valves are easy to disassemble, and the replacement time is less than 30 minutes. The valve body has high manufacturing precision, accurate movement, small size, temperature resistance, corrosion resistance and long life.

It can be automatically switched or manually intervened. Realize control and adjustment of air supply and smoke exhaust volume. The disassembly of the pulse and directional valve body is convenient, and the replacement time is less than 30 minutes at a time. The valve body has high manufacturing accuracy, accurate movement, small external dimensions, temperature resistance, corrosion resistance, and long service life.
