The group of inventions refers to heat exchange machinery. The device includes a tank with an outlet fitting and a steam source, a deaerator column with a cover and water inlet and vapor blowdown fittings located on the same, containing lower and upper deaeration sections. Each section includes pressure and distribution trays forming a jet chamber in the space between them, and random element packing. Deaeration sections are separated by a hydraulic seal formed by the edge of the upper section pressure tray and the projection connected to the deaerator column cover. The water inlet and vapor blowdown fittings are located inside the hydraulic seal projection with openings in it. The lower edges of the openings are located higher than the upper edge of the hydraulic seal by a value exceeding the sum of overflow height of the coolant over the edge and hydraulic resistance of the hydraulic seal channel. The total cross section of the openings is determined by equality of steam pressure in the blowdown fitting and in the space inside the hydraulic seal projection. This increases the operation reliability.

A deaerator includes a tank, a spray unit, a steam supply unit, a bleed unit and a discharge pipe. The spray unit is disposed at an upper portion of the tank and configured to supply water to the tank. The steam supply unit is disposed inside the tank to supply steam to the tank. The bleed unit is disposed at the upper portion of the tank and adjacent to the spray unit. The bleed unit is configured to bleed air from an inside of the tank. The discharge pipe is configured to discharge water without air to an outside of the tank.

Disclosed is an energy storage and steam generation system, including an electrode steam boiler. One side of the electrode steam boiler is connected with a boiler deaerator through a pipeline. A pipeline A is arranged at the top of the electrode steam boiler. The pipeline A is connected with a steam superheater, and an outlet of the steam superheater is provided with an external steam supply outlet pipeline. A molten salt steam generation bypass pipeline and a pipeline B are arranged on the steam superheater. One end of the molten salt steam generation bypass pipeline is connected to the steam superheater. A low-temperature molten salt storage tank is connected to the pipeline B, and a high-temperature molten salt storage tank is connected to the low-temperature molten salt storage tank through a pipeline. The other end of the molten salt steam generation bypass pipeline is connected to the high-temperature molten salt storage tank. Meanwhile, a generation method is further disclosed. According to the present disclosure, electric energy is converted into heat energy to be stored in the molten salt, and then energy is released for external steam supply by means of a method for generating steam through heating by coupling the molten salt, thereby realizing large-scale heat storage, prolonging the life of a heating system, and improving the reliability.

The wastewater treatment system comprising a combustor adapted to burn a fuel and generate pressurized combustion gas therewith. The system also includes gas turbine adapted to expand the pressurized combustion gas and generate mechanical power therewith. The system further includes a boiler adapted to receive expanded combustion gas from the gas turbine. The boiler is fluidly coupled to a wastewater line. In use, heat from the combustion gas generates steam from the wastewater and a brine is removed from the boiler through a brine discharge line. In some embodiments a steam cycle is also provided in the system to extract further power.
