Water-to-carbon ratio during shell gasification

I would like to ask everyone: when gasifying in a shell reactor, adding water increases the concentration of H2 at the outlet, but it reduces the concentration of CO. Yet the total amount of hydrogen and carbon monoxide together still decreases, right? If that’s the case, why add water then to control the temperature of the vaporization furnace? Or control the ratio of hydrogen to carbon monoxide?
I think it’s mainly to control the proportion of CO, because CO + water = hydrogen and carbon dioxide; if there is a conversion process downstream, water isn’t necessary either
Is controlling the proportion of CO intended for future chemical synthesis processes? Methanol, dimethyl ether, etc.
