TUBULAR-AND-ANNULAR COMBUSTION CHAMBER OF GAS-TURBINE POWER PLANT

摘要

FIELD: power engineering; gas turbines burning compressed natural gas. SUBSTANCE: each flame tube 1 of combustion chamber has mixer 7 placed in internal space 5 downstream of flow, behind flame 6, and secured to wall 10 of flame tube 1; mixer 7 is built up of two cones 11 and 12 concentrically arranged relative to wall 10 of flame tube 1. Air vortex generator 13 is installed between walls of cones 11 and 12. Holes 14 and slits 15 are made in wall of external cone 11. Tops 16 and 17 of this cone oppose air flow 18. Surfaces of cones 11 and 12 form annular channels contracting towards vortex generator 13. Space of gas collector 20 is formed by its annular walls 21, 22. EFFECT: reduced emission of nitrogen oxides and carbon into atmosphere. 4 dwge
