    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: An improved apparatus for on-line coal flow control in vertical spindle mills comprising a plurality of independently adjustable flow control elements and positioning rods that adjust the positioning of those flow control elements. Each flow control element is positioned within the discharge turret of the vertical spindle mill along the outer wall of the discharge turret proximate the entrance to its corresponding coal outlet pipe. The adjustable rods are seated on the side or top of the discharge turret of the coal pulverizer and are connected to the flow control element horizontally or vertically as the case may be. The flow control elements can be independently rotated by +/−90 degrees about the positioning rod axis, moved back and forth in the horizontal plane, and can also be moved up and down in the vertical plane. Therefore, each flow control element has three degrees-of-freedom: one rotational and two linear displacements. The apparatus improves boiler performance by making it possible to operate the boiler with reduced pollutant levels (e.g. NOx, CO) and increased combustion efficiency. Automated computer control of the control surfaces is contemplated.

    Abstract: A device and method for controlling fuel-air ratio during combustion of ground in a coal power plant, including pneumatic delivery of ground coal to the burners and feeding combustion air to burners while controlling the combustion air and the amount of carrier air. A high reliability of control combined with low maintenance of the air mass measurement devices is achieved. This is achieved by a measurement device for measuring the amount of combustion air which, according to correlation measurement, evaluates the triboelectric effects on sensors. Between 0.1 mg and 10 mg of fine-grained particles of a diameter between 20 μm and 200 μm are introduced per m3 air into suctioned fresh air, which is carried out during the starting of the firing system. This is done by correlation measurement that evaluates triboelectric effects on sensors, arranged in series in carrier air stream in direction of flow of the carrier air.
