摘要： 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.

摘要： A flow splitter distributes solid particles flowing in a fluid, such as coal particles flowing in air, through a piping system. The flow splitter includes a divider housing having an inlet configured to connect to an upstream pipe and having an outlet configured to connect to a plurality of downstream pipes, e.g., by way of a divider head. A divider body is mounted within the divider housing. A plurality of divider vanes is included, each extending from the divider body to the divider housing. The divider housing, divider body, and divider vanes are configured and adapted to reduce non-uniformity in particle concentration from the inlet and to supply a substantially equal particle flow from the outlet to each of the downstream pipes.

摘要： The invention relates to a turbine engine fuel injection architecture including: two fuel injection manifolds (30A, 30B), each manifold being suitable for dispensing a fuel flow to at least one associated injector; a main fuel-proportioning device (32) suitable for proportioning a total fuel flow (Q) to be supplied to at least both injection manifolds (30A, 30B); and a distribution proportioning device (31), located between the main fuel-proportioning device (32) and the injection manifolds (30A, 30B) and suitable for distributing at least part of the total fuel flow between both manifolds. The architecture is characterized in that it also includes a bypass valve (35) suitable for discharging a flow from a first manifold (30A, 30B) to a second manifold (30B, 30A), in the event of excess fuel pressure in the first manifold. The invention also relates to a turbine engine combustion assembly including said architecture.

摘要： 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.

摘要： The present invention relates to a metering system for the steady, continuous, dosed supply of a bulk material in powder form made of light, polydisperse particles from a supply device (B, SG) into a plurality of conveying tubes (FR1, FR2, FR3) to a consumer arranged downstream. 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.
