BREEZE LFG Fire/Risk provides users with four fire models to choose from for their model run; Confined Pool Fire, Unconfined Pool Fire, BLEVE, and Vertical Jet Fire. These fire models calculate the thermal radiation flux associated with a potential explosion and fire, as well as many other parameters, so users can efficiently analyze the potential risks associated with a specific scenario.
Users have the ability to select between the four fire models by simply clicking the fire model icon on the user-friendly interface.
Confined Pool Fire
Originally developed for the Gas Research Institute (GRI) to model fires that occur when liquid is ignited in a confined area, such as a dike or a tank. The dike may be circular or rectangular. The model calculates the distance to various radiation levels specified by the user and also allows for the calculation of the dynamic temperature rise of a nearby target.
Unconfined Pool Fire
Originally developed for the GRI to model fires that occur when an unconfined spreading pool of liquefied fuel gas ignites. The model calculates the distance to various radiation levels specified by the user (e.g, the 5 kW/m2 level specified by the U.S. EPA in the 112(r) RMP regulations, or the radiant flux levels specified in the U.S. federal standard 49 CFR 193.2057 for LNG facilities) and calculates the radiation flux as a function of time at a given distance as the pool spreads.
Originally developed by the U.S. EPA, the Boiling Liquid Expanding Vapor Explosion (BLEVE) thermal radiation model calculates the thermal radiation level produced by the fire, including the radius within which a specified radiation level will be exceeded. Additionally, the BLEVE model calculates the total amount of thermal radiation exposure over a given time.
Vertical Jet Fire
Originally developed by the GRI to model fires that may result from the leak or rupture of a pipeline containing a compressed or liquefied gas under pressure. The model calculates the distance to various radiation levels specified by the user and can calculate the dimensions of a high velocity jet flame ensuing from a ruptured pipeline.
