FIELD: fire-fighting.

SUBSTANCE: invention relates to a system for ejecting a powdered extinguishing agent and to a fire engine. Said system for ejecting a powdered extinguishing agent includes: a container for fluidising the powdered extinguishing agent; a high-pressure gas source communicating with said container for fluidising the powdered extinguishing agent, configured for pressure adjustment; an apparatus for ejecting the powdered extinguishing agent, communicating with said container for fluidising the powdered extinguishing agent and configured to push out the fluidised gas-powder stream; and a forced injection apparatus configured to direct the flow of forcedly injected gas at a preset pressure to said apparatus for ejecting a powdered extinguishing agent to ensure a preset ejection pressure required for said apparatus for ejecting a powdered extinguishing agent.
