A fracturing device, including a power unit, wherein the power unit comprises a muffling compartment, a turbine engine, an air intake unit, and a starter; the air intake unit is communicated with the turbine engine through an intake pipe, and configured to provide a combustion-supporting gas to the turbine engine; the air intake unit is located at the top of the muffling compartment, the muffling compartment comprises an accommodation space, the turbine engine and the starter are located in the accommodation space, and the starter is configured to start the turbine engine, the starter comprises a first electric motor.

There is provided a fuel tank system comprising a fuel tank; and a lattice in the fuel tank for impeding the propagation of a flame front within the fuel tank, the lattice defining a plurality of openings to allow a fluid to pass through.

The technology relates to a submersible water lifting assembly and automatic fire fighting system for unmanned platforms having said system (1) that is efficient yet simple to install, energy saving, noise free and economical. The submersible water lifting assembly can comprise a High flow Ratio ejector Pump (30/30A) that utilizes under water arrangements of unmanned platform and enables the fire-fighting system to efficiently lift water from the sea water; using the force of existing water injection system; eliminating the requirement of diesel engine driven pump, for lifting the water. It avoids fire risk of the safety system itself, even in conditions of a large fire, unlike that of the prior art.

An oil, water, and gas separator assembly connects a fire extinguishing assembly. When the extinguisher assembly is in operation, sensors indicate an indication to a processor system. If the indication, after processing by the processor system, indicates an unwanted fire condition, the processor actuates the movement of fire extinguishing agent or suppressant from a source of supply to and through a distribution network and into the various hollows delimited by the separator assembly and to the external environment.

A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.

A fire protection sprinkler system includes a horizontal barrier that covers two adjacent racks, and the vertical flue space between the racks. The horizontal barrier is provided at a predetermined height, and has a width that is at least equal to a width of the rack, and a depth that is at least equal to a sum of a depth of the rack, a depth of the other rack, and a depth of the vertical flue space. In addition, the horizontal barrier is a sheet having one or more apertures. The system also includes a rack level fire protection sprinkler connected to a fluid supply conduit, and being disposed in the vertical flue space below the horizontal barrier. The rack level sprinkler has a K-factor of 11.2 gpm/(psi).sup.1/2 or greater, and is vertically spaced from commodities stored on the rack and the other rack covered by the horizontal barrier.
