Embodiment Construction

[0051] figure 1 It shows a hydraulic coupling speed-adjustable feed water pump system with a front pump in the prior art. The existing water supply system with front pump hydraulic coupling speed regulation mainly includes: front pump, main motor, hydraulic coupling, and water supply pump. Such as figure 1 As shown, the front pump takes water from the deaerator, and then the front pump pressurizes the obtained water and sends it to the feed water pump. The front pump is shaft-connected to the main motor, and the other end of the main motor is shaft-connected to the hydraulic coupling, and then the hydraulic coupling is further shaft-connected to the feed water pump, and the water output by the feed water pump passes through the feed water regulating valve, the temperature reduction Regulated by the desuperheater regulating valve, and sent to the boiler through the desuperheater. The boiler distributed control system DCS regulates the water supply.

Abstract

An embodiment of the present invention provides a boiler feed water system, which includes a main motor, a hydraulic coupling and a frequency converter. The frequency converter is configured to be connected to the main motor, and performs electrical speed regulation in a normal working state, and the fluid coupling is configured to perform mechanical speed regulation in an inspection or fault state. Embodiments of the invention also relate to a method for a boiler feed water system.

Description

technical field [0001] Embodiments of the present invention relate generally to water feed systems, and more particularly, to boiler feed water systems and methods for their implementation. Background technique [0002] The power plant boiler water supply system is the key auxiliary equipment in power generation production, and it is also the main energy-consuming equipment. Its operating power accounts for 30% of the total power consumption of the power plant. The energy-saving and economical operation of the boiler feed pump plays a vital role in reducing the power consumption rate of the power plant and improving the overall benefit. [0003] For the sake of safe operation and meeting the requirements of load changes, the design capacity of existing water supply systems is generally too large, and in the actual operation process, it needs to be adjusted in real time according to load changes, which easily leads to the problem of low operating economy. [0004] The basic ...
