The increasing pressure in the explosion-threatened space, housing or container triggers the explosion door lid to open automatically. The explosion venting reduces the explosion overpressure.
The reduced explosion overpressure pred has a value higher than the static response pressure of the explosion door. The value pred which is reached depends on several factors and in the design of the explosion pressure venting concept it must be defined as the highest value to be able to carry out thecalculation of the required vent area for the respective application.
In the event of an explosion the hinged door lid opens once the retaining force of the retaining mechanism is overcome. The lid acceleration is sudden. The lid is therefore damped by a design feature which can withstand the kinetic energy which builds up in the accelerated lid. This kinetic energy is dissipated by a baffle plate.

Constructional explosion protection measures limit the occurring explosion pressure to a calculable level without causing significant damage to the process vessel. Conventional protective systems, however, allow the ingress of atmospheric oxygen. The resulting stack effect often leads to the burning out of large parts of the production plant. With a newly developed explosion protection door (type FSL/Food Super Light), Thorwesten Vent is launching a trend-setting alternative to conventional relief devices in food and feed production. Transport, drying, separation and storage of organic dusts such as starch, gluten, etc. make the danger of an explosion seem omnipresent. Comprehensive explosion protection is therefore of significant importance for product and plant safety.
