"Strong Fire Oil Spurter"
Gunpowder-impregnated fuses for flame-throwers were one of the first uses of gunpowder in warfare in China. The Pen Huo Qi, or continuous flame-thrower was invented ca. A.D. 919, after having acquired the knowledge of the 7th century Byzantine 'spurting' flamethrower. The invention of this continuous flame-thrower is possible because of the dual piston bellows/pump developed a millennia ago during the Han dynasty. A true flamethrower, it could project a continuous unbroken flame of naphtha when it was slow-match ignited with a low-nitrate gunpowder composition.
Whilst often mounted on walls as a defensive device this version is mobile and is used on the battlefield to harass and charge enemy troop positions, projecting a sheet of flame forward to shield advancing infantry following behind it.
