Flare, flaring

Flares. Flares are used for the combustion of waste hydrocarbon gases in which the rates may vary over a wide range and for emergency releases. Steam injection is usually used to enhance mixing and the formation of a clean flame. 

Flares are mostly used for the disposal of hydrocarbons. Waste gases composed of natural gas, propane, ethylene, propylene, butadiene, and butane probably constitute over 95 percent of the material flared. Flares have been used successfully to control malodorous gases such as mercaptans and amines, but care must be taken when flaring these gases. Unless the flare is very efficient and gives good combustion, obnoxious fumes can escape unburned and cause a nuisance. 

Flare and Burners - Certainly the oldest and still widely used technology through some parts of the world is flaring. Flares are used in the petroleum, petrochemical, and other industries that require the disposal of waste gases of high concentration of both a continuous or intermittent basis. As other thermal oxidation technologies, the three T s of combustion of time, temperature, and turbulence are necessary to achieve adequate emission control. 

Flares Flares are used to burn the eombustible or toxie gas to produee eombustion produets, whieh are neither toxie nor eombustible. The diameter of a flare must be suitable to maintain a stable flame and prevent a blowdown (when vapor veloeities are greater than 20% of the sonie veloeity). 

In most hydrocarbon operations excess gas and vapors have to disposed of safety, quickly without environmental impact. Where the gas or vapor cannot be converted into useful energy they are routed to a remote point for safe incineration, called flaring. Flares are the most economical and customary means of disposing of excess light hydrocarbon gases in the petroleum and chemical industries. The primary function of a flare is to convert flammable, toxic or corrosive vapors to environmentally acceptable gases for release into the atmosphere. Both elevated or ground flares can be used.

Primers are not used exclusively for firearm ammunition, but have other uses which include blank cartridges, flares, flare trip wires, mortars, pyrotechnic cartridges, hand grenades, rocket-propelled grenades, ejector seat mechanisms, jettison devices, and other larger ammunition components.

Flares. Flares are considered an acceptable device for emission control. Instances where there is both a sustained high gas flow and a high VOC concentration are rare because the losses would be economically unacceptable. A flare would be effective for controlling intermittent short-term high-flowrate or high-concentration surges.
