Description
Technical Field
The utility model relates to a waste heat boiler system technical field specifically is a horizontal waste heat boiler temperature reduction water system of combined cycle.
Background
At present, the demand of China on energy is rapidly increased, and natural gas resources are used as clean energy and enter a large-scale utilization stage. The installed capacity of a high-parameter gas-steam combined cycle generator set is increased year by year. With the emphasis of the country on energy conservation and emission reduction, all host manufacturers seek effective measures or optimization means to save energy and reduce consumption, the existing high-pressure temperature-reducing water is directly extracted from an outlet pipeline of a high-pressure water supply pump, the parameters are low, and the circulation efficiency of the whole unit cannot be effectively improved.
Disclosure of Invention
In order to solve the problem that the circulation efficiency of current unit is low, the utility model provides a horizontal exhaust-heat boiler of combined cycle subtracts warm water system, its circulation efficiency that can effectively improve the unit.
The technical scheme is as follows: the combined-cycle horizontal waste heat boiler desuperheating water system comprises a high-pressure economizer system, wherein an outlet of the high-pressure economizer system is connected with a high-pressure air bag through a water feeding pipeline.
Adopt the utility model discloses afterwards, when exhaust-heat boiler moves, high-pressure desuperheater water is extracted from the interstage of high-pressure economizer system, gets into the desuperheater pipeline, through the desuperheater water of high parameter, improves the high-pressure steam and exerts power to the last bypass pipeline that has set up of water supply line can select to adjust under high, low-load operating mode, makes the desuperheater water reach the pressure requirement that gets into the desuperheater pipeline, compares in current system, has improved the circulation efficiency of unit effectively.
Drawings
Fig. 1 is a schematic view of the system of the present invention.
Detailed Description
As shown in figure 1, the combined cycle horizontal waste heat boiler desuperheating water system comprises a high-pressure economizer system 1, wherein an outlet of the high-pressure economizer system 1 is connected with a high-pressure air bag 3 through a water supply pipeline 2, stages of the high-pressure economizer system 1 are connected with a desuperheater pipeline 5 through a desuperheating water regulating valve 4, a main regulating valve 6 is arranged on the water supply pipeline 2, and the water supply pipeline 2 is connected with a bypass pipeline 8 of a bypass regulating valve 7.
When the waste heat boiler operates, high-pressure desuperheater water is extracted from the interstage of the high-pressure economizer system 1, enters a desuperheater pipeline through the desuperheater water regulating valve 4, and the output of high-pressure main steam is improved through the high-parameter desuperheater water.
When the waste heat boiler is under the high-load operation condition, the temperature-reducing water meets the pressure requirement of entering a high-pressure main steam pipeline desuperheater pipeline through the adjustment of the main adjusting valve 6, the high-pressure economizer system 1 is ensured not to be vaporized, and the main adjusting valve 6 can realize the 100% adjustment of high-pressure water supply; similarly, when the waste heat boiler is in a low-load operation condition, the temperature-reducing water is adjusted by the bypass adjusting valve 7 to meet the pressure requirement of entering the high-pressure main steam desuperheater pipeline, and the high-pressure economizer system 1 is ensured not to be vaporized, because the load becomes low, the adjusting effect of the main adjusting valve 6 is poor, and the bypass adjusting valve 7 is adopted to realize 30% adjustment of high-pressure water supply.
