Abstract: A solid particle distribution controller includes a plurality of division plates proximate a division between an upstream solid particle conveyance pipe and a plurality of downstream pipes. The solid particle distribution controller also includes a plurality of extension plates. Each of the extension plates is movably mounted proximate to a respective division plate for movement in an upstream and downstream direction with respect to the division plate. The plurality of extension plates are configured and adapted for motion in the upstream and downstream direction independent of one another to extend upstream of the division plates as needed to improve solid particle distribution among the downstream pipes.

Abstract: A dual phase fuel feeder is disclosed that can be used to provide both solid fuels and liquid fuels to a boiler, such as a fluidized bed boiler. The fuel feeder includes a sloped chute which defines a solid feedpath. Gas distribution nozzles are located at the base of the fuel feeder, and secondary nozzles are located so as to be able to distribute a liquid or particulate fuel into the solid feedpath. This permits the liquid fuel to contact the solid fuel and be carried into the fluidized bed instead of becoming suspended above the bed.

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.

The metering system comprises at least two metering containers (DB1, DB2, DB3) each having a delivery device (AE2/1, AE2/2, AE2/3), the delivery device (AE2/1, AE2/2, AE2/3) for each of the conveying tubes (FR1, FR2, FR3) comprising a dust flow regulation device (FI1/1, FI2/1, FI3/2), which is assigned thereto and opens therein, and a mass flow measuring probe (FIC1, FIC2, FIC3) being arranged on each of the conveying tubes (FR1, FR2, FR3), which is coupled to the dust flow regulation device (FI1/1 to FI3/2) which opens into the corresponding conveying tube (FR1, FR2, FR3). Furthermore, the metering system has a pressure regulation device, which is coupled to the pressure measuring devices (PI1/1, PI1/2, PI1/3) arranged on the delivery devices (AE2/1, AE2/2, AE2/3), and which controls a metering container pressure (PIS2/1, PIS2/2, PIS2/3) at least as a function of a metering container fill level (LIS1, LIS2, LIS3). A pump device (V) can be coupled to each of the metering containers (DB1, DB2, DB3), which provides a pressure (PIS2/1, PIS2/2, PIS2/3) in the metering container (DB1, DB2, DB3), which is less than a pressure in the supply device (B, SG). Furthermore, the invention discloses a dense phase conveying system, which comprises the metering system and a method for the steady, continuous, dosed supply of a bulk material in powder form made of light, polydisperse particles.

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 a system for uniformization and regulation of the solid fuels pneumatically conveyed using dense-stream conveying, into a gasifier for the production of synthesis gas, is supposed to be configured in such a manner that clearly homogenized feed of the coal to the burner is made possible, whereby the short-term fluctuations are minimized and thus the gasification quality is improved, and regulation of the amounts of coal to the burner is structured to be more effective. This is achieved in that the fine-grain to dust-type fuel is first conveyed out of a feed container positioned below the burner level, to a level above the burner level, and subsequently homogenized in a line that is directed downward toward the burner.

Abstract: A process is provided using non-food or limited-feed agricultural residue and energy crops for energy production, such as ethanol or electricity generation. The agricultural plant material is harvested and baled. The bales are transported to the processing site for storage or immediate processing. The bale strings are first removed, and then the broken bales are shredded. The shredded plant material is then ground to a small size. The ground material is then pelletized to produce densified pellets of the agricultural plant material. The pellets are cooled and then stored or transported to an end user.
