Title:
HEAT EXCHANGE METHOD
Document Type and Number:
Japanese Patent JP2001304777
Kind Code:
A
Abstract:
To provide a heat exchange method for exchanging heat and at the same time circulate exhaust gas in a rotary type heat storage heat exchanger without increasing the rotary speed of a rotor.
By setting a channel 20 that is formed at a rotor 19 of a rotary type heat storage heat exchanger obliquely to a rotary direction, entry leakage is positively generated in the rotor 19, and one portion of exhaust gas is circulated to a combustion air side. Even if the rotary speed of the rotor is set to 1-5 rpm, exhaust gas can be circulated sufficiently, thus reducing NOx concentration.
