VACUUM HOT-WATER THERMOSIPHON-BOILER Russian patent published in 2018 - IPC F24H1/34 F28D15/02 

FIELD: heat-and-power engineering.

SUBSTANCE: vacuum hot-water thermosiphon-boiler containing a block burner, a heat exchanger for obtaining hot water by means of steam generated by boiling water under vacuum, furnace flue pipe, in the tail part of which vertical heat transfer tubes of the convective beam are welded. Water jacket is a heat exchanger in a volume surrounding the combustion flue pipe, which, together with convective beam tubes, takes heat at all stages simultaneously with the help of radiant and convective heat exchange; a metal mesh made of heat-resistant material is installed in the flue pipe, performing the function of a secondary radiator, which increases the radiant component of heat exchange by the intrinsic radiation coefficient; a diaphragm expansion tank is connected to the steam space of the boiler, providing a preset water temperature at the outlet by compensating for the expansion temperature and representing a vessel divided by a membrane into two chambers, one of which is pressurized with gas or air, the other chamber is connected to the steam space of the boiler.

EFFECT: invention is aimed to increase the thermal and power characteristics of the hot water boiler.
