Fires oxygen-rich

For flexibility, supplementary firing of the oxygen rich exhaust gases can give additional heat. The following summarizes the potential of both the diesel and GT for waste heat recovery ... [Pg.193]

When oxygen-rich air is blown through a copper matte a large amount of SO2 is produced. This is contaminated with dust from the ores and hence it is cleaned by scrubbers and electrostatic precipitators and then fed to the (attached) sulfuric acid plant. This plant consumes all the SO2 and produces sulfuric acid. However, due to copper converter operations, the percentage SO2 and the gas flow vary considerably. External heating sources (oil fired burners) are provided if required and similar workings are used for zinc smelters and to use the SO2 produced for sulfuric acid production. [Pg.14]

Potential targets (5) Hospital staff personnel and/or patients with possible exposure to oxygen-rich conditions creating a potential for fire or explosion... [Pg.111]

At 16 percent you will feel disoriented and between eight percent and 12 percent, you will generally become unconscious. If the air has too much oxygen (over 23.5 percent) it is considered oxygen rich and becomes an explosion or fire hazard. [Pg.151]

Caution Clothing on which liquid oxygen is spilled or clothing exposed to an oxygen-rich atmosphere can pose a serious hazard of fire or explosion due to the rapid chemical reaction between the two substances. [Pg.30]

When the oxygen concentration is more than 35%, an individual may suffer from oxygen toxicity. However, the primary hazard is one of fire or explosion. Many materials not normally combustible will burst into flames in oxygen-rich environments. In an oxygen-rich environment, care must be taken to reduce the inventory of combustible materials, eliminate sources of static electricity, and prohibit smoking. [Pg.256]

Natural uraninites with compositions above UO2.07 usually show broad diffraction lines, which are probably indicative of a range of compositions. Shaner has shown by metallography that samples fired at high temperatures in controlled atmospheres do not quench but separate into two phases, one oxygen-rich and the other oxygen-poor. The details of the two-phase field UO2+A—U4O9 in Fig. 1 were determined in this manner. Natural samples probably behave in a similar manner in that the oxidation to UO2.2J probably occurs stepwise, affecting only part of a sample at a time. [Pg.46]

The error bars show the range of experimental C-J pressures measured in various geometries. The correlation is good for all the high performance explosives except PETN. PETN is the most oxygen-rich, has the fastest kinetics, smallest reaction zone, fastest Forest Fire rate, and least build-up of any of the explosives. [Pg.267]

Oxygen-Rich versus Fuel-Rich Fires The distinction between an oxygen-rich or fuel-rich fire is used to describe the state of the fire relative to a nominal or stoichiometric combustion process. In the oxygen-rich state there is sufficient oxygen to allow for, theoretically, complete combustion of the available fuel. Remember that the combustion process is a series of competitive equilibrium chemical reactions therefore, it is fair to assume that not all of the intermediate products will be fully converted in the reaction chain. Growth of a fire in the oxygen-rich state is marked by direct heat transfer from the flame to the additional fuel supply. The exhaust gases mix readily with available fresh air and are cooled and diluted. [Pg.370]

Reburning is a process involving staged addition of fuel into two combustion zones. Coal is fired under normal conditions in the primary combustion zone and additional fuel, often gas, is added in a reburn zone, resulting in a fuel rich, oxygen deficient condition that converts the NO, produced in the primai y combustion zone to molecular nitrogen and water. In a burnout zone above the reburn zone, OFA is added to complete combustion. [Pg.447]
