Abstract
1,098,116. Preheating air for combustion; feed water heating. BABCOCK & WILCOX Ltd. March 1, 1966 [March 1, 1965], No. 9039/66. Headings F4A and F4B. [Also in Division F1] During normal operation of a steam turbine plant, combustion air supplied by a fan 8 to a boiler 1 is preheated in a heater 4 by steam bled from a turbine 3 while part of the feed water from a condenser 13 is preheated in a heater 5 by further steam bled from the turbine, the remainder of the feedwater being preheated in a flue gas cooler 12. At peak load, valves RA, RE are closed and valves RD, RC are opened, and the combustion air is then heated by an auxiliary combustion chamber 6. Since steam is no longer being bled from the turbine 3 to supply the heater 4, the turbine develops extra power to meet the peak load. The valves RA, RE, RD, RC can be set to intermediate positions at loads between normal and peak. At superpeak load a further increase of turbine power is provided by operating a valve 20 to reduce or stop the bleed of steam to the feedwater heater 5, the feedwater being correspondingly diverted to the flue gas cooler 12 and the heat input to the latter being correspondingly augmented by means of an auxiliary combustion chamber 7 fed by a fan 11. The combustion chambers, 6, 7 operate on liquid or gaseous fuel. A duct 9 with a valve RB enables the heater 4 and combustion chamber 6 to be connected in series. When the boiler 1 is being started up, it can be preheated by the combustion chamber 6. In a modification, the flue gas cooler 12 is supplied with feedwater from a point within the heater 5 so that part of the heater 5 is in series with it and the remainder is in parallel with it.
