In some cases the flame arrester cannot be positioned within a distance of 50 times that of the pipe diameter (50D) from the start of the flame (ignition source); a stable detonation may then develop. The force of such a detonation is substantial and our detonation-safe KITO® detonation type flame arresters should be used. The detonation flame arrester element is specially designed to withstand the resulting pressure wave whilst still maintaining its flame arresting properties (fig. 6).
German regulations do not require flame arresters certified against unstable detonation; nevertheless we developed a series suitable for this (fig.7).
Selection of a suitable detonation flame arrester is based on the gas group classification of the gas. Our manufacturing range covers KITO® detonation flame arresters for all explosion groups
(fig. 8, fig. 9, fig. 10).
Their use is normally certified for atmospheric pressure & temperature, but models are also available for increased pressures/temperatures.
KITO® Detonation flame arresters may be installed anywhere in the pipe line, and bi-directional, meaning they offer protection from both directions. The flame elements are economically designed for low pressure losses with ease of maintenance.
Under some operating conditions, such as installation in torch/flare lines or thermal afterburning plants, we recommend the fitting of a thermal sensor(s) at the flame elements. These sensors will signal a valve to close or similar method of isolating the gas flow thus preventing the possibility of continuous burning.
