A jet fire, also known as a spray fire if the fuel is a liquid or liquefied gas, is a turbulent diffusion flame of flammable material. [3] The characteristics of a jet fire depend on a number of factors. These include: fuel composition; release conditions; release rate; release geometry; direction; and ambient wind conditions.
A gas non-return valve (NV), which: prevents dangerous gas mixtures. ensures the gas only flows in the intended direction. and a flame arrestor (FA), which: cools the flame to below the ignition temperature of the gas or gas mixture. prevents flashback. In addition to these two basic safety functions a flashback arrestor can also have a:
A rupture disc (burst) Pressure-effect acting at a rupture disc A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
In traditional systems over-pressure is dealt with through relief systems. A relief system will open an alternative outlet for the fluids in the system once a set pressure is exceeded, to avoid further build-up of pressure in the protected system. This alternative outlet generally leads to a flare or venting system to safely dispose the excess ...
Naval InFrared Thermal Imager. A device used aboard naval ships to help locate hotspots where fire or personnel may be located in a dense smoke environment. Nozzle A device attached to the end of a fire hose that directs, shapes and regulates the flow of the water or fire fighting agent pumped into the hose. May have a control valve.
A ribbon style (long with holes), inshot (torch-like), or oil type burner is located in the heat exchanger. Ignition is provided by an electric spark , standing pilot, or hot surface igniter. Safety devices ensure that combustion gases and/or unburned fuel do not accumulate in the event of an ignition failure or venting failure.
The fourth category of furnace is the high-efficiency condensing gas furnace. High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as ...
