Abstract

The invention discloses a dynamic regulation method for the power of a high-voltage electrode boiler. In order to ensure that the high-voltage electrode boiler can quickly reach the load power when the device is put to use for initial commissioning, a servo motor can quickly open a protection shield according to the set power requirement, so that a high-voltage electrode can work at a set power. Circulating water flow of a bypass is adjusted through a three-way valve, and the bypass of a circulating water pipeline is completely opened in the initial stage. As the temperature of the circulatingwater gradually rises, the conductivity is increased. When the power of the boiler gets greater, the temperature is rapidly increased along with the temperature, and therefore the purpose of fast heating is achieved. According to the method, a slope function stepped means is adopted for adjusting the power value, and the bypass opening degree value is adjusted by combining a three-way valve stepped manner. The power value can be quickly adjusted, a peak adjusting command is responded, the power adjusting speed is high, and system vibration cannot be caused.
