An electronic cooking apparatus having a steam supply device for supplying steam to a cooking chamber of an oven is provided. The electronic cooking apparatus may include a steam generating device including a steam supply portion that generates steam and supplies the steam to a cooking chamber, and a water level sensing module that senses a level of water inside of the steam supply portion using a low water level sensor and a high water level sensor. In addition, the electronic cooking apparatus may include a water supply pump that supplies water from a water tank to the steam supply portion; a drain pump that collects condensed water from the steam supply portion to the water tank; and a controller that controls on/off operations of the water supply pump or the drain pump according to a change in the level of water in the steam supply portion sensed by the water level sensing module.

According to the disclosure, a position of a main control valve and a position of an auxiliary control valve are adjusted. In particular, a position of the auxiliary control valve is adjusted by determining whether a change in the position of the main control valve is in a preset deadband range, thereby preventing a periodic water level fluctuation of a steam generator.

A hydronic system having a set of inputs, a plurality of boilers, and a controller. Each input representing sensor for a respective heat emitter of a set of heat emitters. Each boiler of the plurality of boilers is configured to receive signals from a portion of the set of inputs. The controller is configured to a status and assignment of the set of inputs from the plurality of boilers and control the plurality of boilers to provide heat to the set of heat emitters.

Provided are a method and system for improving control of a steam generator level for preventing oscillation of the steam generator level in a nuclear power plant. In order to prevent oscillation of a steam generator level and resultant shutdown of a nuclear reactor, which may be caused when a high-level priority control function is frequently and repeatedly turned on/off as the steam generator level is excessively increased, by improving a feedwater control system in the nuclear power plant, a proportional integral control value may be controlled to be reduced, and thus, output while a certain condition is met after a high-level priority mode is deactivated or a signal instructing to enter the high-level priority control mode may be controlled not to be output.

Provided is a steam generation method for a steam generation system The method includes: S1, controlling the liquid pump (3) to operate, driving liquid from the liquid inlet (1) through the inlet valve (4) to the steam heater (5) in a heating state; S2, during the operation of the liquid pump (3), controlling the inlet valve (4) to alternately open and close at a preset frequency, causing the liquid to intermittently pass through the inlet valve (4). The liquid, after passing through the inlet valve (4), is delivered in a pulsed flow to the steam heater (5), where each pulsed flow continuously moves and is at least partially evaporated to produce steam before exiting the steam heater (5).
