Title: Gas turbine combustor
Inventor: YAMANAKA CHIKAU
IPC: F23R3/16
Filed: 1982-09-09
Abstract: PURPOSE:To provide the titled device with an capability of maintaining a preset low ignition temperature, by arranging a group of columns transversely across a gaseous mixture stream between catalysts of honeycomb structure. CONSTITUTION:A visible radiation ray emitted between an upstream and a downstream sections can be shielded by a group of columns arranged in a zigzag manner between two catalysts of honeycomb structure. Moreover, a gaseous mixture is caused to change its flowing direction upon its collision with columns, resulting in bringing about a further mixing action. As a result, it is relatively easy to control the flow velocity of gaseous mixture at an even level after passed across the group of columns. The diameter, number and installation pitches etc., of columns may be determined with a basis on the magnitude of pressure drop required with an arrangement 8. The replacement of arrangements 8 can be performed conveniently by premounting the group of columns as a unit upon a cylinder which can be inserted into the inner diameter of combustion.
