DEVICE FOR IGNITION OF FUEL Russian patent published in 2001 - IPC

FIELD: devices for ignition of liquid, gel-like, suspension, as well as solid fuels. SUBSTANCE: device has a sleeve of conducting material filled with fuel, electric power source with leads and a key, internal electrode, and metal fuse links. The internal electrode, positioned in alignment with the sleeve, passes through the whole volume of fuel and is secured in the sleeve bottom of electric insulating material. The metal fuse links located in fuel connect the internal electrode to the sleeve. One pole of the electric power source is connected to the sleeve, and the other through the key - to the internal electrode. The distance between the links located near the free end of the electrode may be less than that near the sleeve bottom by 1.5-2 times. The device may have an additional source of electric power and an additional tubular electrode insulated from the internal electrode by an insulating insert. EFFECT: stable quasi-volume multisource ignition for a shorter time than by traditional methods; successive ignition of various parts of the charge. 4 cl, 2 dwg
