DOUBLE-MODE CATALYTIC HEATER Russian patent published in 2013 - IPC F23C13/00 F23D14/18 

FIELD: electricity.

SUBSTANCE: double-mode catalytic heater comprises a catalytic attachment and a fuel tank connected to it, fuel in which is retained in a porous hygroscopic filler, and fuel vapours arrived to the catalytic attachment from the open window of the fuel tank, which simultaneously serves for fuel filling, differing by the fact that the working window of the catalytic attachment (with area S1) has a certain eccentricity ℮ relative to the axis of the attachment symmetry, and the evaporation window of the fuel tank (with area S2-S1) has the same eccentricity relative to the axis of symmetry of the tank itself, which makes it possible to join the catalytic attachment and the fuel tank in two different positions, and thus to implement two modes of thermal capacity of the heater: the mode of maximum thermal power - when areas of windows coincide with each other - S_max=S1=S2, and the mode of minimum thermal capacity - when areas of the windows cross with each other S_min = S1 ∩ S2.

EFFECT: increased operational reliability and functional capabilities of a catalytic heater.
