Flame and Explosion suppression using Pyrobubbles
41,10 € *
ggf. zzgl. Versand

An alternative fire extinguishing agent "pyrobubbles" was investigated to suppress the spread of gaseous flame after explosion. Pyrobubbles are foam-like granules made from silicon dioxide or inorganic raw materials with a diameter of 1.5 to 5.0 mm and have the following superior properties, not inflammable, outstanding asphyxiation, and melting point above 1200 °C, floatable, very high flowability and quick filling ability, heat and cold insulation. Using pyrobubbles as fire extinguishing agent was tested for its ability to suppress the spread of gaseous flames after explosion. In order to demonstrate this experimentally, a flame quenching effect of pyrobubbles was tested in the laboratory under defined conditions with different explosible gas mixtures such as methane and hydrogen gas in two different laboratory equipments. In this book, the various mechanisms of explosion and detonations were discussed. The various methods to supressed gaseous flames as well as flame arrestors were also discussed. The results indicate that pyrobubbles are more effective with respect to suppression of gaseous flame.

Fire retardant polyolefines
34,70 € *
ggf. zzgl. Versand

The book presents a modern understanding of combustion and reducing the flammability of polyolefins by modifying various fire retardants, and methods of evaluating flammability of modified polymeric materials.All methods to reduce the flammability of polymers are based on the following principles: a) a change in the thermal balance of the flame due to the increase in various kinds of heat losses, b) reduction of the heat flux from the flame to the polymer due to the creation of protective layers, such as formed coke, c) reduction of the gasification rate of the polymer and d) a change in the ratio of combustible and non-combustible decomposition products material in favor of non-combustible. As flame retardants metal oxides and hydroxide, halogen, phosphorus and silica containing compounds, expandable graphite, nano clays and other modificators are described.

The Northern Light
60,70 € *
ggf. zzgl. Versand

In Nordic literature a remarkable discussion of the northern light appears in Kongespeilet (The King's Mirror) a thirteenth-century Norwegian chronicle. It is described in vivid detail as the following translated excerpts demonstrate: These northern lights have this peculiar nature, that the darker the night is, the brighter they seem, and they always appear at night but never by day, most frequently in the densest darkness and rarely by moonlight. In appearance they resemble a vast flame of fire viewed from a great distance. It also looks as if sharp points were shot from this flame up into the sky, these are of uneven height and in constant motion, now one, now another darting highest, and the light appears to blaze like a living flame. Three different theories for the origin of the northern light were suggested in this book. Numerous naturally occurring heavenly phenomena have been observed and enjoyed as long as the Earth has been inhabited, but hardly any of them has stirred man's imagination, curiosity and fear as much as the northern light. The northern light is certainly one of the most spectacular of nature's phenomena.

Propagation and Extinction Studies of Laminar L...
126,61 € *
ggf. zzgl. Versand

This thesis presents pioneering experimental and numerical studies on three aspects of the combustion characteristics of lean premixed syngas/air flames, namely the laminar flame speed, extinction limit and flammability limit. It illustrates a new extinction exponent concept, which enriches the combustion theory.Above all, the book provides the following: a) a series of carefully measured data and theoretical analyses to reveal the intrinsic mechanisms of the fuel composition effect on the propagation and extinction of lean syngas/air flames, b) a mixing model and correlation to predict the laminar flame speed of multi-component syngas fuels, intended for engineering computations, c) a new "extinction exponent" concept to describe the critical effects of chemical kinetics on the extinction of lean premixed syngas/air flames, and d) the effects and mechanism of the dilution of incombustible components on lean premixed syngas/air flames and the preferential importance among the thermal, chemical and diffusion effects.
