Naturally Circulated High Efficient Boiler Air Preheater for Power
Station ASME Standard
Product Description
Air pre-heater is a kind of equipment used to improve the heat
exchange performance and reduce energy consumption of the boiler,
which means that the flue gas in the tail flue of the boiler will
preheat the air before entering the boiler to a certain temperature
through the internal radiator. Air preheater is generally divided
into three types: plate type, rotary type and tube type. Taking the
rotary type as an example, the working principle of air preheater
is introduced. A large number of unburned combustibles will deposit
on the heat transfer elements, which may cause the air preheater to
ignite. The causes of ignition and the countermeasures are
described in detail. The shutdown analysis and air leakage control
are also introduced in detail.
Different types
For the use in Steam Generators (boilers)in Thermal power stations of Utility power stations, there are two types of design of the Airpreheaters. One is a tubular type built into the boiler outlet Flue_gas ducting and another one is of the regenerative type known as Ljungstrom (named after the name of inventor) Regenerative Air Pre Heater(RAPH),a rotating type. This may be horizontal (now very common in power generation utilities) or vertical.
