Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a cleaning agent for a hydrogen cooler of a generator and its application. Background technique [0002] The hydrogen cooler is a device for heat exchange between hydrogen and cooling water, and is an important part of the generating set of a thermal power plant. In order to ensure the safe and stable operation of the generator set, the cold hydrogen temperature of the generator must be controlled within the specified range. Once the cold hydrogen temperature is too high, the heat of the stator and rotor coils of the generator cannot be taken away smoothly, and the generator set will face shutdown. Serious consequences. Especially in summer, the temperature is high. When the temperature is above 38°C, the hydrogen temperature at the outlet of the hydrogen cooler will increase accordingly, and may reach the alarm value of 46°C or even exceed this value, which will serio...
