STEAM GENERATOR Russian patent published in 2008 - IPC F22B33/18 

FIELD: heating.

SUBSTANCE: steam generator is made from several cyclones, with parallel connection to a battery between an upper steam collector and a lower collector of boiler water. A steam pipe is joined to the upper steam collector. On the feed water pipeline, after the feed water heater, there is a cyclone separator, the steam connection pipe of which is joined to the upper steam collector, while its water connection pipe is joined to the input in the end part of the lower collector of boiler water, on the side of the first cyclone along the flow of the feed water. An outlet pipe is joined to the output of the opposite end of the lower collector of boiler water. Along the length of the lower collector of boiler water, there is a series of water discharge pipes, joining it to water collectors of evaporation surfaces of each cyclone. The steam generator can have several parallel-serial connections of cyclone batteries. The input of the lower collector of boiler water of the second, along the flow of feed water, and the subsequent battery, is connected to the output of the lower collector of boiler water of the previous battery and to the water connection pipe of the cyclone separator of the given battery.

EFFECT: increased efficiency and reliable operation of the steam generator.
