METHOD OF OPERATING GAS ENGINES WITH LOW-CALORIFIC CH-CONTAINING GAS AND MIXER TO THIS END

摘要

FIELD: engines and pumps.SUBSTANCE: invention relates to propulsion engineering, particularly, to operation of gas engine with low-calorific CH-containing gas. In compliance with proposed method, gas engines can run on low-calorific gas with CH-concentration makes under 25 vol. %, in particular, without engine modifications. Low-calorific gas is divided into two separate flows. Said first separate flow is fed to first Venturi gas mixer and mixed with airflow jet to make air-low-calorific gas mix. Said second separate flow is fed to second Venturi mixer and mixed with said airflow jet air-low-calorific gas mix. Air-low-calorific gas mix from second Venturi gas mixer is fed to gas engine or turbo compressor ahead of gas engine as combustible gas mix.EFFECT: high-efficiency mixer.15 cl, 2 dwg
