UTILISATION STEAM BOILER PLANT Russian patent published in 2009 - IPC F22B1/18 F01K23/10 

FIELD: heating.

SUBSTANCE: invention concerns utilisation of exhaust gas heat of steam and gas plants and can be applied in heat power industry. Boiler plant includes steam reheaters, evaporisers and double- or triple-pressure economisers, separator drum of lower pressure, and thermal deaerator. Deaerator is connected to low-pressure condensate economiser output at deaerated condensate input, and to feed water inputs of low-pressure drum and high- and medium-pressure economisers at feed water output. Low-pressure steam reheater is made in the form of water steam reheater connected to water output of medium- or high-pressure economiser at heating water input, and to heating heat carrier input of deaerator at heating water output.

EFFECT: improved performance of low-pressure steam, simplified system of boiler plant control.
