 Characteristics

‘

For heat recovery form the exhausted gas of 800-- 1,400Ž.  the gas/air of low temp. side can be heated to 800Ž from air temp.

‘

High temp. gas is flowed in the inside cylinder and Low temp. gas is flowed between
Inside cylinder and outside cylinder.

‘

many fins are attached on the outside surface of  inside cylinder for cooling efficiency.

‘

In case of gas radiation, CO2 and H2O is used for the thermal radiation and the content of  CO2 and H2O is high in high temp. gas side.  That is, this type heat exchanger is suitable for the ultra high temperature.

‘

High temp. gas is flowed in large diameter inside cylinder with slow speed, It is suitable for high dusts content gas  and pressure drop is very low.

‘

There are two type, self-standing type and hanging type.

‘

In case of cage type, many tubes are installed in cylinder and it is more suitable for high temp. exhausted gas.
