20120006157 | METHOD FOR MELTING A SOLID CHARGE - A simple, compact burner achieves a more optimal melting of a solid charge followed by performance of combustion under distributed combustion conditions. The burner achieves this by fluidically bending the flame towards the solid charge during a melting phase with an actuating jet of oxidant, redirecting the flame in a direction away from the charge, and staging injection of oxidant among primary and secondary portions during a distributed combustion phase. | 01-12-2012 |
20120009531 | DISTRIBUTED COMBUSTION PROCESS AND BURNER - During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved. | 01-12-2012 |

20120304905 | Solid Fuel and Oxygen Combustion with Low NOx and Efficient Burnout - Solid particulate fuels are combusted with a primary oxidant stream of industrially pure oxygen and a secondary oxidant stream of industrially pure oxygen optionally mixed with a portion of recycled flue gas. The fuel is conveyed with a carrier gas of air or recycled flue gas. An oxygen concentration out of the total amount of the fuel stream and the primary and secondary oxidant streams is 40-63% by mass or 47-70% by volume. | 12-06-2012 |
20130255551 | Biomass Combustion - A splitter divides a flow of low heating value biomass into a central stream and an annular stream. A stable flame may be achieved by combusting the central stream with oxygen. This avoids the use of costly fossil fuels or biomass (that have higher heating values than the biomass fuel) as an auxiliary fuel for achieving a stable flame. | 10-03-2013 |
