The operating voltage for a jet-type electrode boiler may be as high as _________ kilovolts?

In the context of jet-type electrode boilers, the operating voltage is a critical aspect that influences their efficiency and performance. Jet-type electrode boilers can operate at high voltages due to the nature of their design, which utilizes electrodes to directly heat water through electrical resistance.

The correct operating voltage can reach up to 25 kilovolts for jet-type electrode boilers. This higher voltage allows for effective operation, enabling the boiler to generate steam rapidly by passing a significant amount of current through the water. The use of elevated voltages is essential in ensuring that the electrodes can provide the necessary thermal output efficiently.

Higher voltages beyond this range, such as those indicated by some of the other choices, are typically not standard for jet-type electrode boilers and could involve safety and operational efficiency concerns. A comprehensive understanding of these voltage limits is vital for ensuring safe and proper installation and operation of electrical boilers.
