GAS-LIQUID ATOMIZER WITH TWO-STAGE SUPPLY OF ATOMIZING AGENT Russian patent published in 1995 - IPC

FIELD: heat power engineering. SUBSTANCE: gas-liquid atomizer has the first (1) and second (2) atomization stages contained in the same box 3. The first atomization stage uses nozzle 4 for supply of fuel to fuel-air mixture passage 5 consisting of contracting part 6 at the beginning, and then of expanding part 7, with formation of minimum flow area F₁. The second atomization stage comprises an extension of expanding part 7 of passage 5, with taper angle α being within 5 to 8 deg, slotted hole 10 located in the point of flow area F₂, air supply 11 to hole 10 and outlet 12 of mixture from atomizer. Hole 10 is positioned in section whose flow area exceeds the minimum flow area of the mixing chamber by 3 to 4 times. EFFECT: improved design. 1 dwg
