Fire extinguishing equipment with fire nozzle

A fire extinguishing equipment with fire nozzle, comprising:

• a gas-dynamic propelling nozzle, connected to a mixing chamber with inlets for the supply of high pressure air and water and foam in the mixing chamber, a chamber for the formation of a two-phase bubble-structured stream, wherein the fire extinguishing equipment is equipped with a water pump, wherein the fire nozzle is connected to a compressor of a gas-turbine engine or the fire nozzle is connected to a screw compressor connected to a diesel engine, the mixing chamber configured for the formation of a high-speed two-phase dispersive stream of a bubble structure is made in the form of a block of mixers having front partition and rear partitions, between the front and rear partitions are located pipe mixers,
• the rear partition is located in the chamber, wherein the chamber has an inlet for the supply of water and foam and an inlet for the supply of high pressure air,
• the inlet for the supply of high pressure air is situated between the front and rear partitions, and
• an inlet orifice of each pipe mixer has a confusor connected to a chamber for the supply of water,
• the pipe mixers are fitted from a side of the rear partition with side orifices and outlet orifices of pipe mixers are equipped with diffusors, outlet ends of the diffusors with gaps are located in the outlet orifices of pipe mixers in the front partition,
• and the required number of pipe mixers is defined so that as the total flow of pressurized water through one mixer is 1.9 to 2.1 litres per second and the flow of compressed air from the compressor through one mixer is 40 to 28 litres per second.
