TL;DR: In this article, the authors describe a turbine-driven carbon-blck production system with a turbofan engine, an afterburner downstream of the turbine, and a furnace-type carbon-black reactor.
Abstract: Apparatus and method are disclosed for manufacturing carbon blck. The apparatus includes in contiguous axial alignment, a turbofan engine, an afterburner downstream of the turbine and a furnace-type carbon black reactor having means for radial introduction of feedstock. In a preferred embodiment, the turbine provides a first stream of high temperature, high pressure oxygen-containing gas to the afterburner for further combustion and subsequent use as supply air for a first carbon black reactor, and also provides a second stream of lower temperature and pressure air for cooling the first reactor shell and for use as supply air to a second carbon black reactor. This abstract is not to be construed in any way to define or limit the invention set forth below.

TL;DR: In this paper, an integrated after-burning system for drying ovens can operate continuously and uses the heat generated in the after burner to heat the drying oven, which is controlled by a damper in a by-pass round the mixing chamber.
Abstract: Integrated after-burning system for drying ovens can operate continuously and uses the heat generated in the after burner to heat the drying oven. Regulation of the heat input to the oven is controled by a damper in a by-pass round the mixing chamber. The burner feed is adjusted synchronously with this damper in order to maintain a temp. of 600-800 degrees C in the afterburner. The heat present in the flue gas is used in a heat exchanger to warm the fresh air necessary to maintain the furnace atmosphere below the lower explosive limit.

TL;DR: In this paper, a gas turbine and an afterburner are operated with a dual liquid fuel system, and logic controls are provided for initiating a transfer from operating fuel to a flushing fuel after predetermined conditions are satisfied.
Abstract: A gas turbine and an afterburner are operated with a dual liquid fuel system. During protective stops, logic controls are provided for initiating a transfer from operating fuel to a flushing fuel after predetermined conditions are satisfied. After fuel transfer, shutdown is completed without setting trips and restart can be achieved without special prestart preparation of the fuel system.

TL;DR: In this paper, an improved fire fighting arrangement has no superfluous components and it is hence compact without losing its efficiency, which can be used for fighting fires in mines and also for preventing explosions in mines.
Abstract: The fire fighting arrangement is based on a gas turbine engine. An inert gas is used for fire fighting and this can be used for fighting fires in mines and also for preventing explosions in mines. The improved fire fighting arrangement has no superfluous components and it is hence compact without losing its efficiency. The gas turbine blows air into an afterburner chamber into which is blown fuel through a distribution. This afterburner chamber is water cooled and the cooled inert combustion gases are used for fire fighting purposes. The igniter (5) chamber (8) of the afterburner chamber (3) is connected by a pipe (9) with the high pressure zone of the engine (1). The fuel distributor outlets may face the air stream for better fuel distribution.

TL;DR: In this paper, the authors present ways and means for incinerating organic wastes in a multiple hearth furnace equipped with an afterburner, where air is introduced to complete the oxidation of the partially oxidized substances carried by gases and vapors from the furnace.
Abstract: The following disclosure teaches ways and means for incinerating organic wastes in a multiple hearth furnace equipped with an afterburner. In the furnace, the wastes are pyrolyzed in an oxygen deficient atmosphere which is regulated to only partially complete the oxidation of the organic substances which are pyrolyzed from the wastes. In the afterburner, air is introduced to complete the oxidation of the partially oxidized substances carried by gases and vapors from the furnace. The air supply to the afterburner is controlled so that, at temperatures above a predetermined temperature, the quantity of air introduced is increased with increasing temperatures and is decreased with decreasing temperatures. In other words, the pyrolyzing furnace is caused to operate with a deficiency of air over its operating range, while the afterburner is caused to operate with excess air and the amount of excess air supplied is used to control the operating temperature by quenching.

TL;DR: In this paper, a four-stroke engine which normally runs on a lean mixture comprises between an afterburner and combustion chambers exhaust pipes which are not in communication with the atmosphere.
Abstract: Four-stroke engine which normally runs on a lean mixture comprises between an afterburner and combustion chambers exhaust pipes which are not in communication with the atmosphere, so that unburnt fuel in the exhaust gases is oxidised in the afterburner only by 02 residues contained in the exhaust gases. Means are provided for enriching the mixture to produce the stoichiometric mixture ratio under thermal overloading of the afterburner. The afterburner may contain heat-sensitive elements which actuate the mixture adjuster according to temp. in the afterburner. The ratio of air-to-fuel is pref. below 16.
