STEAM BOILER Russian patent published in 2005 - IPC

FIELD: generation of steam; heat supply systems.

SUBSTANCE: proposed steam boiler has several interconnected sections of combustion chambers with burners located inside them. Each section has passages made in form of water jacket or in form of spiral of screw feeder secured around cylindrical combustion chamber and provided with guide passages for flow of water around cylindrical combustion chamber; water jacket is provided with cover and framework; water jacket may be made in form of one or several rows of longitudinal passages located over perimeter of combustion chamber in parallel to each other and interconnected together by means of U-shaped branch pipes; water jacket may be also made in form of spiral passages having cross section in form of circle or oval located on inner surfaces of covers and on outer surfaces of cover framework. Electrolyzer is provided with covers and reservoirs. Located in electrolyzer batteries are electrodes which may be made in form of plates or corrugations or brush-shaped or cellular, comb-type and tubular structure. Electrode cathodes and anodes are interconnected in succession and are connected with current source by means of electric circuit through rotary converter, pulse generator and electrical switches which convert AC to DC, low-voltage current to high-voltage current, forming high-voltage pulse discharge of tens of thousands of volts and performing electrolysis. Electrolyzer is connected with liquid alkali reservoir through proportioner equipped with solenoid and time relay. Outlet branch pipes of electrolyzer reservoir are located at different levels: upper branch pipe is located above reservoir cover and lower branch pipe is located above electrolyte level; branch pipes are connected with burner by means of couplings, gas lines, vacuum pumps, sections of accumulator reservoirs, reducers and valves; they are used for extraction and separation of hydrogen and oxygen and for motion of them to burner. Thermal elements of thermo-electric generator are mounted on steam boiler sections.

EFFECT: enhanced efficiency.
