Environmental Upgrading of GTN-16 Gas-Pumping Unit Combustion Chamber FREE

The results of research into development of engineering approaches to environmental update of the GTN-16 16 MW gas-pumping unit combustor are presented. The built-in “disc” combustor of the GTN-16 is noted for having a small length and very low hydraulic resistances. The multi-burner low-NO_x combustor design was developed in a test rig. The “lean” fuel/air premix combustion was adopted as the basis for the design.

The proposed environmental update of the GTN-16 combustor does not bring about any changes in the most costly material-intensive and labour-consuming components of the combustor, viz. casing, frame, liners. No changes were also made in the automatic control system. It is noteworthy that a similar approach is appropriate for the “Turbomotorny Zavod” (Ekaterinburg, Russia) GTN-25 type 25 MW unit.
