一种燃气热电厂一拖一机组凝结水系统及其启停方法
摘要：
本发明提供了一种燃气热电厂一拖一机组凝结水系统及其启停方法，燃气热电厂一拖一机组凝结水系统包括：凝结水前置泵再循环主路、凝结水前置泵再循环旁路、第一凝结水前置泵支路、第二凝结水前置泵支路、第一凝结水泵支路、第二凝结水泵支路、凝结水再循环主路、凝结水再循环旁路、凝结水前置泵再循环管路、凝结水再循环管路、第一凝结水前置泵、第二凝结水前置泵、第一凝结水泵、第二凝结水泵、凝汽器、轴封加热器及除铁过滤器。本发明可以在全停状态下，实现凝结水系统的自动启动；在运行状态下，实现凝结水系统的自动停止并且在部分启动的状态下实现凝结水系统的自动启动，且不干扰原有的运行状态。
摘要（英）：

The invention provides a gas thermal power plant one-dragging-one set condensate system and a start and stop method thereof. The gas thermal power plant one-dragging-one set condensate system comprises a condensate booster pump recirculating main path, a condensate booster pump recirculating bypass, a first condensate booster pump branch, a second condensate booster pump branch, a first condensate pump branch, a second condensate pump branch, a condensate recirculating main path, a condensate recirculating bypass, a condensate booster pump recirculating pipeline, a condensate recirculating pipeline, a first condensate booster pump, a second condensate booster pump, a first condensate pump, a second condensate pump, a condenser, a sealing heater and a deironing filter. According to the gas thermal power plant two-dragging-one set condensate system, automatic start of the condensate system can be achieved under the full-stop state, automatic stop of the condensate system can be achieved under the running state, automatic start of the condensate system can be achieved under the state of partial start, and the original running state cannot be disturbed.
