flue boiler
4.Through measuring residual swhirling flow field in the flue duct of a real boiler, and analysing layout features of front and back platen supe-heaters in large-scale tangential firing boilers, the flue gas energy distribution regularity in horizontal flue duct of tangential firing boilers has been studied.
5.RELATION BETWEEN THE VOLUME HEAT LOAD OF UPPER FURNACE AND THE FLUE GAS TEMPERATURE DIVIATION FOR TANGENTIAL FIRING BOILER
9.Some energy saying measures were carried out in the FCC unit of the 2nd Refinery during 1980,including:the use of CO-combustion promotor,energy recovery from flue gas,rearrangement of heat exchanges,steam generation by waste heat,and boiler feed water preheat by low-temperature effluents,resulting a decrease of energy consumption by 65×10~4 kcal/ton of feed.
