HEATING DEVICE Russian patent published in 1999 - IPC

FIELD: radiation heating devices at flameless catalytic oxidation of gaseous fuel. SUBSTANCE: device includes housing where porous radiation panel and working chamber are mounted. Radiation panel is covered by closed metal protective screen with distributed catalyst. Manifold provided with injectors and connected with fuel reducer is arranged in working chamber. Innovation of invention consists in availability of ignition torch adjoining radiation panel. Ignition torch is connected with fuel reducer through receiver which is common with radiator manifold and made in form of branch pipe with valve and coaxial nozzle whose ejection peripheral air passages are inclined at angle of 27 to 36 deg relative to axis of ignition torch; radiation panel is made from basalt fibres. EFFECT: enhanced functional reliability due to reduced content of toxic agents in combustion products; enhanced efficiency of automatic lighting-up of gas burner. 2 cl, 2 dwg
