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

Abstract

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-NOx 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.

“…The calculation of a particular mixture's combustion temperature is a rather difficult task, as the initial temperature, pressure strongly afect the mixture's composition (Soudarev et al, 1997). The increase in temperature and pressure of the initial components leads to the combustion temperature increase (Sukhinenko et al, 1995).…”
