If more excess air is used it will cool the furnace and flue gas and stack temps. Superheater temps may also be reduced because of total furnace heat reduction has occured. Pressure should not change unless load changes dramatically. Part 2 of your question, Radiant superheat temps will be reduced as load increases because the flow velocity of the steam has increased and is traveling faster thru the superheater, and cant pick up any more heat. Also other superheater convective will increase in temps with increase in loads and the inlet temps to the radiants may be increased. with these increased inlet temps the temperture differential may be lower.There are three-methods to find all the replies to this steam or power forum question or answer: 1) Use the 'Next >>' or '<< Previous' menu links above, or 2) Look at the year of the post and click on the applicable year an scan the postings for the date/title, or 3) Use the 'View Post Tree' feature, which is new to help you find all tree-truncations to the postings and replies on the steam & power forum that you are interested in.
