Abstract
Embodiments described herein relate to firefighting foam generators. The generators may include a receptacle for receiving liquid. A gas supply may be provided for supplying gas into the liquid to create foam. At least one turbulence creator may be provided for creating turbulence in the receptacle. Advantageously, the firefighting foam generators create turbulence to assist with mixing the gas and liquid when creating the foam. The embodiments provide for improved mixing and evenness of foam, without foam flooding, when compared with known foam generators. The embodiments are also simple to manufacture when compared with known foam generators.
Claims17
A firefighting foam generator including:
- a receptacle for receiving a flow of liquid;
- a gas supply for supplying pressurized gas into the flow of liquid to create foam, the gas supply comprising a tube which extends into the receptacle transverse to the flow of liquid, the tube includes a plurality of gas outlets, and
- a first and second turbulence creator, each for creating turbulence in the receptacle,
- the first turbulence creator including a baffle positioned within the receptacle at a first location spaced apart from and upstream of the tube, relative to the flow of liquid, and
- the second turbulence creator including a baffle positioned within the receptacle at a second location downstream of the tube, relative to the flow of liquid,
- each turbulence creator comprising an edge, positioned transverse to the flow of liquid which extends between and contacts the receptacle at a first position and a second position.
