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.

The present invention relates to the field of fossil fuel combustion arrangement. It relates in particular to a fuel distribution assembly for equal and homogenous pulverized fuel distribution in pulverized fuel conduits throughout. It also relates to a system for providing an equal and homogenous pulverized fuel distribution.

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.

A multi-deck burner assembly for a conveyor-type oven can include a central manifold feeding fuel to upstream and downstream arrays of burners. Other burner assemblies can include pilot burners disposed at approximately a midway point along a longitudinal direction of the burners, thereby enabling the use of longer burners, and thus more efficient burner assembly design. Some burner assemblies can include both a centrally located manifold feeding upstream and downstream arrays and pilot burners disposed at approximately midpoints along the longitudinal lengths of both the upstream and downstream arrays.

A split control unit in a distributed flow unit includes a flow inlet configured to receive a fuel flow, a first manifold having flow lines to supply fuel to one or more primary nozzles, and a second manifold having flow lines to supply fuel to one or more secondary nozzles. In an embodiment, the second manifold is in fluid communication with the flow inlet. A metering valve has a first port in fluid communication with the flow inlet and with the second manifold. The metering valve is configured to supply a metered fuel flow to the first manifold. A flow passage is in fluid communication with, and runs between, a flow line of the first manifold and a flow line of the second manifold to allow for a continuous cooling flow in the second manifold when all of the one or more secondary nozzles are closed.

Methods and systems for a fire device, comprising a common fuel line coupled to a fuel source via a first pressure regulator, wherein the first pressure regulator is configured to provide gaseous fuel from the fuel source to the common fuel line at a first pressure. A first fire display device is coupled to the common fuel line via a second pressure regulator, wherein the second pressure regulator is positioned downstream of the first pressure regulator and provides the gaseous fuel to the first fire display device at a second pressure that is lower than the first pressure.
