    Abstract: A fossil-fuel-fired system, which includes an emissions-control-agent dispenser, a furnace, an emissions monitor and, optionally, a controller, is disclosed. The emissions-control-agent dispenser provides a prescribed amount of organic-emissions-control agent, such as, for example, an opacity-control agent to the fossil-fuel-fired system. The furnace includes an exhaust communicating with the atmosphere. The emissions monitor is capable of measuring at least one property of the flue-gas communicated through the exhaust to the atmosphere. For example, when an organic-emissions-control agent is an opacity-control agent, the emissions monitor has the capability of at least measuring opacity. When included, the controller communicates with at least the emissions-control-agent dispenser and the emissions monitor.

    Abstract: A method and apparatus for delivering biomass fuel to a structure through an external wall of the structure is disclosed. The apparatus comprises a hopper disposed within a delivery vehicle. The hopper includes an inlet disposed on its top surface to receive biomass fuel and an outlet located proximate the bottom of the hopper to release the fuel by opening a gate valve. A delivery hose is connected to the hopper outlet at one end and is sealably connectable at its other end to an externally accessible coupling disposed on an external wall of the structure to which fuel is to be delivered. The coupling is connected on the interior side of the external wall to a delivery pipe that connects to a fuel bin for storing the biomass fuel. Sensors within the bin can signal the operator when the level of fuel within the bin reaches a preselected level, allowing the operator to stop delivery when the bin is full.

    Abstract: An adjustable device installed at the inlet of conventional junctions/splitters (116) for on-line control of the distribution of coal among the outlet pipes is herein disclosed. The device includes a plurality of wake inducing airfoils (60) each positioned upstream of a plurality of flow channels in the riffler (50) for directing coal flow to the outlet pipes. Each wake-inducing airfoil has a cross-section defined by a width W that varies along its length H for creating upstream turbulence, and a particle wake that preferentially diverts the coal flow to one of the outlet pipes at the splitter junction without affecting primary air flow. For example, each wake inducing airfoil may comprise a rounded convex edge leading to straight tapered sides. The surfaces of the sides may be roughened or textured (63) for promoting turbulent boundary layers. In addition, conventional fixed or variable orifices may be used in combination with the wake inducing airfoils for balancing primary air flow rates. The device allows fine-adjustment control of coal flow rates when used in combination with the slotted riffler, yet it has negligible effect on the distribution of primary air, resulting in closely balanced coal flow, reduced pollutant emissions and improved combustion efficiency.

    Abstract: An adjustable device installed at the inlet of conventional junctions/splitters (116) for on-line control of the distribution of coal among the outlet pipes is herein disclosed. The device includes a plurality of flow control elements (60) each positioned upstream of a plurality of flow channels in the riffler (50) for directing coal flow to the outlet pipes. Each flow control element preferably comprises a rounded convex edge leading to straight tapered sides (FIG. 9). The surfaces of the sides may be roughened or textured (63) for promoting turbulent boundary layers (FIG. 9). In addition, conventional fixed or variable orifices may be used in combination with the flow control elements for balancing primary air flow rates. The device allows fine-adjustment control of coal flow rates when used in combination with the slotted riffler, yet it has negligible effect on the distribution of primary air. The combination of the riffler assembly and the coal flow control elements (60) results in closely balanced coal flow. Balanced coal flow is imperative to the optimization of the operation of pulverized coal boiler systems (i.e. reduced pollutant emissions, improved combustion efficiency).

    Abstract: A combustion system having a furnace defining a combustion chamber includes a first burner disposed at an upper elevation of the combustion chamber and a second burner and a third burner disposed at a lower elevation of the combustion chamber. A first duct extends vertically to convey therein a fuel flow of gas and pulverized fuel. A second duct branches from the first duct to the first burner to convey a first portion of the fuel flow, which is fuel lean, to define a fuel lean flow, wherein a second portion of the fuel flow passes through the first duct as a fuel rich flow. A third duct includes one end disposed longitudinally within the first duct. An impeller is disposed within the first duct upstream of the branching of the second duct and downstream of the one end of the third duct disposed in the first duct. The impeller includes a plurality of blades to direct outwardly the pulverized fuel of the fuel rich flow to provide a fuel reduced content flow passing through the second duct to the second burner, and a fuel concentrated content flow passing through first duct to the first burner.
