Territory.
Background technology
Air preheater, is called for short air preheater, is utilize boiler tail flue gas heat to heat the required air of burning one
Kind of heat-exchange device, swinging (also referred to as Junker formula) air preheater is that a kind of heat accumulating type being widely used in Power Station Boiler Heating Surface is empty pre-
Device.
Power boiler burning required air is generally divided into First air, secondary wind two kinds, and First air is that pulverized coal conveying enters burner hearth
Part air, typically provided by primary air fan, its effect is except maintaining certain primary mixture concentration so that defeated
Outside sending, also to provide enough oxygen for fuel at the burning initial stage, be referred to as heat primary air through the First air of air preheater heating.Secondary
Wind is the air being sent into burner hearth by the individual passage of burner, enters gradually with wind facies mixing after burner hearth, carries for burning
Oxygen, and the disturbance of air blast can be added, promote the backflow of high-temperature flue gas, promote the mixing of combustible and oxygen, for firing completely
Burning offer condition, secondary wind is typically provided by pressure fan, is referred to as hot secondary wind after air preheater heats.
Conventional station boiler rotary regenerative air heater is three points of storehouse air preheaters, uses three points of chamber structures, and rotor is by solid up and down
Determining fanning strip and be separated into flue gas, First air and three heat exchanger channels of secondary wind, general flue gas accounts for the flow area of 50%, and one, two
Secondary wind adds up to the flow area accounting for 50%, according to first and second air quantity, pathogenic wind-warm needed for boiler, designs primary and secondary air passage ratio,
After fanning strip fixed installation, its heating surface ratio is the most fixing.But in boiler Actual combustion, often because of coal-fired ature of coal, powder process
Change with boiler plant situation etc. causes that actual first and second air quantity ratio is not inconsistent with demand, duct resistance is big, heat primary air temperature
Spend the problems such as (or higher) on the low side, exhaust gas temperature be higher, and first and second air quantity ratio required under different load operating mode is the most not
Identical, the adjustment to primary and secondary air channel for heat exchange area ratio seems particularly necessary.
Authorization Notice No. is the Chinese utility model patent (authorized announcement date is on January 4th, 2015) of CN204100284U
Disclosing a kind of adjustable rotary regenerative air preheater of aisle spare, its rotary regenerative air preheater includes cylinder-like shell, if
Put the uniform dividing plate on the rotary shaft and extended of the rotary shaft in shell center and inner side along rotating shaft axis direction, every
