PDF Boiler circulation calculations

For water tube boilers, heat flux, q = Uo x (tg - ts) x At/Ai ,Where Uo = overall outside heat-transfer coefficient, Btu/ft2-hr-°F tg, i s are gas and steam temperatures, °F At, Ai are the tube outside and inside surface areas, ft2/ft. This ratio is for bare tubes, while for finned tubes it could be high, say 5 to 12. Hence, one must be careful
