A water delivery apparatus (100) for use at a household appliance is provided. The water apparatus comprises an air-tight water storage unit (110) configured to store water, an air channel (120) configured to allow air to enter the water storage unit at a predetermined height level so as to regulate the water pressure in the water storage unit, and a water delivery tube (130) connected to a component of the household appliance at which water is utilized for performing a function of the household appliance.

A water heater according to the present invention includes: a heating unit that includes a burner provided to cause a combustion reaction from air and fuel, and that is provided to generate heated water by using heat generated by the combustion reaction; and a humidifier unit that generates water steam by evaporating water using a combustion gas generated by the combustion reaction and discharged from the heating unit, and provides the water steam together with the air to the burner.

A device for cleaning workpieces with a steam jet is proposed, with a special steam generator in which the steam is generated in a hollow cylindrical core, whose outer side is heated and onto whose inner side the water to be vaporized is sprayed by means of a nozzle. The steam generator has a supplementary heating device with a heatable body having a cavity through which steam generated upstream can flow for post-heating it, in order to generate dry steam for dry steam cleaning. An automated cleaning system with this steam generator is also proposed. The device can be adapted flexibly to the requirements of automated synchronized production and requires, in particular, less energy and floor space. The invention can be used, among other things, in industrial cleaning in manufacturing systems engineering, in particular in the production of automotive parts.

The invention relates to a steam generator tool configured to receive a supply of fuel, oxidant, water and power/control, and therefrom, to combust the fuel and generate steam from the water. The tool can be used downhole or on surface. The tool includes a tool coupling component configured to receive inputs of water, fuel, oxidant and power/control; a flow diversion component coupled to the coupling component and which directs the inputs into the tool; and an ignition component configured to ignite the fuel to produce a flame. Tool further includes a combustion chamber configured to accommodate the flame; and a plurality of water nozzle on the external surface of the tool configured to eject water onto the outer surface of the combustion chamber, the water being converted to steam during operation of the tool. The tool coupling component forms a first, which may be considered the upper end of the steam generator tool and the combustion chamber is at the second, opposite end of the tool.

A process and a device are described for producing high purity and high temperature steam from non-pure water which may be used in a variety of industrial processes that involve high temperature heat applications. The process and device may be used with technologies that generate steam using a variety of heat sources, such as, for example industrial furnaces, petrochemical plants, and emissions from incinerators. Of particular interest is the application in a thermochemical hydrogen production cycle such as the Cu—Cl Cycle. Non-pure water is used as the feedstock in the thermochemical hydrogen production cycle, with no need to adopt additional and conventional water pre-treatment and purification processes. The non-pure water may be selected from brackish water, saline water, seawater, used water, effluent treated water, tailings water, and other forms of water that is generally believed to be unusable as a direct feedstock of industrial processes. The direct usage of this water can significantly reduce water supply costs.

Liquid is flash evaporated in a series of cells along and surrounding an exhaust duct to generate a pressurized vapor where at least one of the surfaces is in communication with the source of heat sufficient to maintain the surface at a temperature such that the liquid injected into the chamber is substantially instantly converted to a superheated vapor with no liquid pooling within the chamber. The liquid is introduced by controlled injectors operating at a required rate. Each of the cells is periodically discharged by a pressure controlled relief valve and the vapor from the cells combined to form a continuous stream feeding a turbine or other energy conversion device. The outer wall of the cell is offset so that it contacts the inner wall at one point around the periphery. Heat transfer ribs and bars can be provided in the duct to provide increased heat transfer where necessary.
