Background
Softened water (containing supplementing water) for thermal power plant equipment enters the deaerator after being regulated by a water inlet regulating valve, is mixed with other drainage in the deaerator, is sprayed out by a perforated pipe to form a skirt-shaped water film, and is subjected to mixed heat and mass transfer with heating steam, and the water supply rapidly reaches the saturation temperature under the working pressure. At this time, most dissolved oxygen and other gases in the water are basically resolved out, so that the aim of deoxidizing is fulfilled. Dissolved oxygen and other gases separated from the water are continuously discharged out of the deaerator along with residual steam from a steam discharge pipe at the top of the deaerator. The deoxidized water is boosted by a water supply pump and then is supplied to equipment of a thermal power plant. Dissolved oxygen, water vapor and other gases (including free CO2 and N2) separated out from water in the operation of the thermal deaerator are continuously discharged from a steam exhaust pipe at the top of the deaerator along with residual steam, and the residual heat of the part of steam exhaust directly causes resource waste for air exhaust, wherein the contained heat is directly discharged to the atmosphere, and the operation mode not only can influence the environmental temperature, but also indirectly reduces the efficiency of the unit.
The production mode of heat power plant not only producing electric energy, but also utilizing steam generated by the steam turbine generator to supply heat to users refers to the process of simultaneously producing electric energy and heat energy, and compared with the mode of respectively producing electric energy and heat energy, the fuel is saved.
