ABSTRACT:
This invention provides a method and apparatus for transferring heat to a cooler gas from a hotter gas which contains tri-atomic molecules with good infra-red energy absorption characteristics, for example CO.sub.2. The hotter gas is passed in a first direction along a conduit, and simultaneously the cooler gas is jetted through and across the hotter gas in a direction transverse to the hotter gas direction. This allows the tri-atomic molecules minimally entrained in the cooler gas jets to provide heat to the cooler gas firstly through transferring their initial kinetic energy to the cooler gas molecules by way of collision, and secondly by absorbing infra-red energy radiated from the hotter gas and passing this absorbed energy to the cooler gas molecules also through collision.
