BURNER FOR SYNTHESIS-GAS GENERATOR Russian patent published in 2004 - IPC

FIELD: fuel burning devices. SUBSTANCE: proposed burner has housing with supply axial passage communicated with side natural gas and gaseous oxygen passages; housing is blanked off at inlet end of supply axial passage and outlet end is embraced by cooling water cavity; outlet end of burner is provided with longitudinal peripheral passages used for supply of natural gas separated from cooling water cavity embracing these passages by wall made of heat-conducting metal; supply axial passage is widening in stepwise manner towards outlet; it is bounded by coaxial surfaces: larger and smaller; natural gas side passages are made in form of tangential holes which are equidistant over circumference; oxygen side passages are also made in form of tangential holes smoothly distributed over circumference. Circular baffle plate made at area of stepped change of smaller and larger axial surfaces is used for disconnection of part of supply axial passage forming end well with larger coaxial surface. Ratio of total area of flow sections of tangential natural gas holes to total area of flow sections of oxygen tangential holes ranges from 0.1 to 0.5; larger and smaller coaxial surfaces are cylindrical in shape and ratio of areas of flow sections ranges from 1.3 to 3. Ratio of total area of flow sections of longitudinal peripheral passages to area of outlet section of axial passage ranges from 0.9 to 1.1; ratio of total flow rates of oxygen to natural gas ranges from 1.36 to 1.6 and ratio of flow rates of natural gas through side passages and longitudinal peripheral passages ranges from 0.05 to 0.15. EFFECT: increased specific volumetric productivity. 7 cl, 4 dwg
