Description

Deaerator bay
Technical field
The present invention relates to technical field of power generation, disclose a kind of deaerator bay for arranging heat regenerative system.
Background technique
The major parameter for influencing water supply backheat heating economics is backheat heating distribution, corresponding optimum feed temperature and returns Thermal level number.Power industry such as generally uses at the temperature rises method, rises the enthalpy of every primary heater equal.Traditional heat regenerative system steam extraction Temperature is very big, and corresponding bleeder heater heat transfer temperature difference increases, and irreversible loss caused by the temperature difference exchanges heat increases, and UTILIZATION OF VESIDUAL HEAT IN Rate is lower.
Traditional deaerator bay is often chronically at low load condition when reducing using hourage.When encountering underload, such as Under 30%HTA operating condition, it may appear that the pressure difference between low-pressure heater is inadequate, and often the water column pressure difference of 5m does not all have, normal to dredge Water often blocked drain.Power plant will open emergent drain to condenser, recyclable hydrophobic heat be wasted, when causing underload Heat consumption increases, and reduces unit economy.By primary Calculation, the hydrophobic of every 1t/h is not recycled, and heat consumption increases 0.25KJ/kw.h, Annual coal consumption increases, and annual gene-ration revenue is reduced.
Summary of the invention
The present invention provides when can overcome the problems, such as underload using difference in height that low plus hydrophobic is unsmooth, reduces hydrophobic heat waste It loses, reduces coal consumption, increase the deaerator bay of generated energy.
Deaerator bay, for arranging heat regenerative system, the heat regenerative system, including No.1 high-pressure heater, No. two hyperbaric heatings Device, No. three high-pressure heaters, No. four high-pressure heaters, oxygen-eliminating device, No. six low-pressure heaters, No. seven low-pressure heaters, No. eight it is low Press heater, No. nine low-pressure heaters, No. ten low-pressure heaters, condenser, condensate pump, drainage pump, feed pump, first external Formula steam condenser and the second externally arranged steam cooler;
