| 20080282945 | Pulverized coal combination burner - Disclosed is a burner for oxidant gasification of pulverized fuels under high pressures of e.g. 80 bar (8 MPa) and temperatures of e.g. 1200 to 1900° C. in reactors with liquid slag removal for oxygen gasification, the individual pulverized fuel supply tubes in the burner are designed such that, while retaining the entry cross-sectional area of the tube, the cross-section makes a systematic transition to a curved rectangular duct matched to the annulus. This means that fuel feeding ends immediately adjacent to the oxidant duct, and the flow rate provided in the feeding element is maintained up to the outlet, thereby ensuring trouble-free flow of the pulverized fuel and reducing the amount of inert gas required for purging the feeding element in the non-operational state. | 11-20-2008 |
| 20090205546 | Densified fuel pellets - A biomass-based fuel pellet, such as a fuel pellet which includes thermoplastic polymeric material and a substantial amount of cellulosic material, e.g. cellulosic material derived from biomass source(s), is provided. The fuel pellet commonly includes about 5 to 15 wt. % of the thermoplastic polymeric material and at least about 75 wt. % cellulosic material. Optionally, the fuel pellet may comprise a lignin additive. Many embodiments of the fuel pellets are suitable for use in a coal-fired furnace and/or in other industrial boiler applications. | 08-20-2009 |
| 20090272303 | Anti-roping Device for Pulverized Coal Burners - An orifice plate for improving particle distribution within a coal piping system includes a plate body defining a central orifice therethrough bounded by an inner periphery of the plate body. The plate body is configured and adapted to be affixed between end flanges of adjacent pipes in a coal piping system so as to generally align the central orifice with an internal flow passage through the coal piping system. Flow disruption features are defined in the inner periphery of the plate body. The flow disruption features are configured and adapted to disrupt a flow of air and particles flowing through the central orifice to provide a more uniform distribution of particles downstream of the plate body than upstream. | 11-05-2009 |
| 20100058961 | PULVERIZED COAL BURNER - Slagging is prevented from occurring in a pulverized coal burner. | 03-11-2010 |
| 20100154688 | COAL ROPE DISTRIBUTOR WITH REPLACEABLE WEAR COMPONENTS - A head assembly | 06-24-2010 |
| 20100192817 | Burner nozzle for pulverized coal - A coal nozzle for a burner on a pulverized coal fired furnace which includes an elongated tubular nozzle having an inlet for receiving a flowing stream of coal/air mixture and an outlet for discharging the flowing stream into a combustion zone of a furnace for combustion, and an inlet elbow connected to the inlet of the tubular nozzle. The interior outer surfaces of the elbow include a staircase surface configuration for engaging the incoming flowing stream whereby coal ropes in the stream are broken up for thereby improving flow distribution of the stream. | 08-05-2010 |
| 20100307391 | PULVERIZED FUEL BURNER - The invention provides a pulverized fuel burner including a nozzle body | 12-09-2010 |
| 20110048293 | NOZZLE FOR FEEDING COMBUSTION MEDIA INTO A FURNACE - In a boiler furnace having nozzles for introducing combustion media such as air and coal, nozzle tip walls that have the greatest exposure to radiant heat and hot gases are provided with arrays of air holes that allow air to flow to the exposed sides of the walls from the opposite sides in order to reduce the temperature difference between the two sides and thereby reduce thermal distortion and damage resulting from oxidation. | 03-03-2011 |
| 20110239915 | Adjustable Diffusing Coal Valve - An adjustable, diffusing coal valve for use in controlling flow of air and pulverized fuel to a burner is disclosed. An exemplary embodiment comprises a conduit section having an inner cross-sectional area and a diffusing damper plate mounted to said conduit section and rotatable within the conduit section between an open position and a closed position. The diffusing damper plate has a periphery dimensioned to occupy a majority, but less than all, of said inner cross-sectional area when in the closed position, and includes a plurality of perforations distributed within an outer region of the plate, thus allowing coal particles to flow through the damper plate when it is in a closed or partly-closed position. | 10-06-2011 |
| 20120037054 | Burner - A burner for introducing solid particulate fuel to a burning zone of a kiln such as a rotary kiln for manufacturing cement clinker or similar material includes a centrally located duct for conducting solid fuel to an inlet opening and at least one duct for conducting primary air to one or more annular nozzles surrounding the inlet opening of the centrally located duct. The centrally located duct for conducting solid fuel is arranged so that the direction of introduction of the fuel relative to the longitudinal axis of the burner and consequently the direction of introduction of the primary air may be adjusted continuously during operation of the burner. | 02-16-2012 |

| 20130319301 | Spray Nozzle, and Combustion Device Having Spray Nozzle - A spray nozzle is provided with upper and lower channels and from respective surfaces, the two channels form a cross shape, and become a fuel spray hole by communication of an intersecting part. A guide member is provided, in contact with the upstream-side channel, in a position overlapped with the intersecting part with respect to the spray direction of the spray nozzle. Spray fluid is branched with the guide member from the fuel fluid duct connected to the spray nozzle, passes through the upstream-side channel, to the intersecting part, and is sprayed. The spray fluid forms opposed flows toward the intersecting part in the upstream-side channel to collide with each other at an obtuse angle of 90° or greater, then is sprayed from the intersecting part, to form a thin fan-shaped liquid film. The liquid film is divided by a shearing force from the peripheral gas, atomized into spray particles. | 12-05-2013 |
| 20140144353 | SOLID FIRED HOT GAS GENERATOR WITH EXTENDED REGULATING RANGE - The invention relates to a solid fired hot gas generator which comprises a plurality of solid burners for extending the regulating range, which form a multiple solid burner with an enlarged regulating range. A solid feed and a combustion air feed are assigned to each solid burner and with the aid of a dosing means a separate, dosed solid feed to each solid burner is guaranteed. The firing power of the multiple solid burner which is in particular a multiple impulse burner extends from the minimum power of one of the solid burners to the maximum power of all solid burners so that a regulation of all necessary load regions of a plant unit to be supplied is covered. | 05-29-2014 |
