Problems solved by technology
[0002] The high back pressure circulating water heating of the air-cooling unit is to use the high back pressure of the original design of the unit for high back pressure operation, and recover the exhaust loss of the low-pressure cylinder. , due to the large amount of exhaust steam, the small amount of circulating water and the small heating area, only a part of the exhaust steam loss can be recovered
During the high back pressure circulating water heating operation, the back pressure of the unit is operated from the designed 13kPa to 35kPa. Since the exhaust steam of the low pressure cylinder cannot be completely recovered, the unrecovered exhaust steam of the unit is also discharged into the air cooling island at a high back pressure of 35kPa, resulting in low work efficiency , Increased coal consumption for power generation and energy waste reduce the benefits of high back pressure circulating water heating

The invention discloses a double back pressure circulating water heating system for an air cooling unit, comprising a low-pressure cylinder A and a low-pressure cylinder B, the outlet of the exhaust pipe of the low-pressure cylinder A communicates with the inlet of the condenser through the exhaust valve A, and the outlet of the condenser passes through The condensate valve is connected to the condensate system A, the outlet of the exhaust pipe of the low-pressure cylinder B is connected to the air-cooled island B through the exhaust valve B, the condensate system B is connected to the outlet pipe of the air-cooled island B, the condensate system A, the condensate system B and the condensate The outlet is connected. The invention operates according to the double back pressure circulating water heating system of the air-cooling unit, realizes that the 600MW air-cooling unit can recover part of the exhaust steam loss of the low-pressure cylinder, and does not affect the work efficiency of the other part of the exhaust steam and the coal consumption of power generation. The design is reasonable, energy is saved, and the improvement unit efficiency.
Description
technical field [0001] The invention relates to the technical field of heating, in particular to a double back pressure circulating water heating system of an air cooling unit. Background technique [0002] The high back pressure circulating water heating of the air-cooling unit is to use the high back pressure of the original design of the unit for high back pressure operation, and recover the exhaust loss of the low-pressure cylinder. When , due to the large amount of exhaust steam, the circulating water volume and the small heating area, only a part of the exhaust steam loss can be recovered. During the high back pressure circulating water heating operation, the back pressure of the unit is operated from the designed 13kPa to 35kPa. Since the exhaust steam of the low pressure cylinder cannot be completely recovered, the unrecovered exhaust steam of the unit is also discharged into the air cooling island at a high back pressure of 35kPa, resulting in low work efficiency ,...
