Tom I don't think we are discussing a water shift reaction, just the 
way steam can be involved with burning CO to CO2, Hugh posted an 
equation, which I didn't understand, which seemed to demonstrate how 
steam could alter the rate of the reaction. Penn tried to interpret 
the equation for me.

The issue is how the steam (costly in energy terms as the latent heat 
of vapourisation is lost up the flue) could be beneficial. Could 
this heat loss be offset by the turbulence it introduced, through a 
small jet,  by better mixing? Which may enable less excess air 
AND/OR could the steam assist a reaction and offer better heat 
transfer properties.
