    Abstract: The invention relates to an indirect heating system in which a solid fuel circulates in the form of particles. The inventive system comprises a grinding station, a furnace (7), at least one intermediate silo, a separator, at least one cyclone and, optionally, a gas recirculation fan. The invention is characterized in that a dust extractor (10) captures the finest particles which are subsequently introduced into the furnace (7) by means of at least one specific conduit (52) and burnt by at least one specific burner (71). The aforementioned ultra-fine particles are then stored in a specific silo (10), dosed into a feeding device (61), mixed in well defined proportions with hot air and conveyed to the specific burner (71) through the specific conduit (52).

    Abstract: A system for fluidizing and conveying a powdery product is provided. The system includes plurality of powder-locking and metering vessels, the vessels each having a conveying line for the powdery product and a control mechanism for the mass flow of the powdery product. The conveying lines are brought together to form a common conveying line and are supplied to a remover of the powdery product. The powder-locking and metering vessels are alternatively fed with the powdery product and tensioned with the fluidizing gas under operating pressure. The control mechanisms of the powder-locking and metering vessels are activated in such a manner that the mass flow sum of powdery product in the conveying lines is identical to the desired value for the mass flow of powdery product to the remover of the powdery product.

    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.

    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 for retrofitting a solid fuel pulverizer and exhauster system includes replacing the bowl drive motor 38 with a new drive motor which is operable to drivingly rotate the bowl 12 at the pre-retrofit speed but which provides relatively more horsepower than the replaced bowl drive motor 38 and replacing the original exhauster fan coupling with a new exhauster fan gear set 46, 48 which effects rotation of the exhauster fan 30 at a relatively higher rotational speed than the pre-retrofit speed. A solid fuel pulverizer and exhauster system of the present invention acting in cooperative association with a fuel-fired steam generating power plant includes an exhauster fan transmission assembly 50, 52 operable to translate the rotation of the drive shaft 54 of the exhauster fan drive motor 44 through ninety (90) degrees to thereby effect rotation of the fan by the exhauster fan drive motor 44.
