CATALYTIC HEATER WITH SPRAYING CAVITY Russian patent published in 2013 - IPC F23C13/00 F23D3/40 

FIELD: power engineering.

SUBSTANCE: catalytic heater comprises at least one fuel reservoir, at least one tube connected with at least one reservoir, at least one porous tube connected with at least one tube and directed into a cavity, and a cavity limited with a porous catalytic wall, which is in diffusion contact with an oxidising gas, for provision of catalytic burning with fuel from at least one porous tube, besides, oxidation may take place on porous catalytic walls between molecules of an oxidant, arriving by means of diffusion outside from porous catalytic walls, and plasma inside the cavity spreading by means of diffusion in direction of catalytic walls, in which plasma is formed from evaporated fuel, released via at least one porous tube, so that as a result of oxidation heat is generated. In the heater fuel boils. At least one tube includes tubes of fuel supply, having small diameter and large length for limitation of a liquid fuel flow into at least one porous tube, at the same time fuel tubes of supply are in thermal contact with catalytic burning, besides, fuel evaporates in fuel tubes of supply, and as a result of volume increase the speed of fuel flow supply via supply tubes reduces. Porous catalytic walls comprise a porous matrix of a material of a high-temperature substrate and a coating from a catalytic material. Porous catalytic walls comprise a jacket for a matrix. The jacket for the matrix is arranged in the form of a heat conductor, with the possibility of circulation of fluid medium. Porous catalytic walls comprise mineral wool, coated with catalysts, selected from the group containing platinum, palladium, rhodium, copper, zinc, nickel, iridium, tin, osmium, ruthenium, silver, titanium oxide, iron and transition metals.

EFFECT: invention makes it possible to generate heat and electricity as a result of reaction of oxidation inside a cavity having porous catalytic walls.
