FIELD: heating.SUBSTANCE: invention relates to a catalytic burner for heating the vehicle. The catalytic burner for burning a mixture of fuel and blowing air comprises a mixing chamber (24), a device (36) for supplying the blowing air, a device (28, 34) for supplying fuel, a device (46) of the catalyst with at least one unit (48, 50, 52) of the catalyst, a combustion chamber (44), a nozzle (18) with a circumferential wall (20) and a base wall (22). The device (28, 34) supplying fuel is located downstream of the mixing chamber (24) and comprises a porous evaporating device (28) receiving liquid fuel and discharging fuel vapour into the mixing chamber (24). The area of the internal volume of the nozzle (18) forms at least one part of the mixing chamber (24). In the circumferential wall (20) of the nozzle (18) there is at least one passage hole (42) leading to the combustion chamber (44). At least one portion of the porous evaporation device (28) is provided on the circumferential wall (20) and/or the wall (22) of the base of the nozzle (18) on the side facing away from the combustion chamber (44).EFFECT: increase in efficiency of the catalytic burner.15 cl, 10 dwg |
