A Software for the Calculation of Explosion Protection Devices for Dust, Gas and Hybrid Mixtures

In publishing the Guideline VDI 3673 Part 1, November 2002 the issue VDI 3673, 1995 is being recalled. Consequently WinVent 2.x and 3.0 must also be recalled and replaced with the new WinVent 3.1.

Based on the new release of the guideline VDI-3673 Part 1, November 2002, the book of W. Bartknecht "Explosionsschutz, 1993", the draft of the EN standard "Dust Explosion Venting Systems" and NFPA 68, "Edition 1998". The software calculates all the required information for explosion venting of vessels, silos and rectangular enclosures.

Complete calculations are given by the maximum recoil force, the duration of the recoil as well as the transferred impulse, flame and pressure development in the vicinity of vented equipment.

Versatile in choice of dust dispersion, type and shape of venting device and influence of the vent pipe.

Easy to use while WinVent runs under Microsoft-Windows 95 / 98 / NT / 2000 / ME / XP. The comprehensive and illustrated help gives additional information and practical hints.

WinVent 3.1e and European Standards. The question was often raised if the WinVent 3.1e program can still be used even the following 2 Standards are published: EN 14491-2006: Protective systems for the pressure relief of dust explosions and the EN 14994-2007: Protective systems for the pressure relief of gas explosions.

In Europe no obligation consists that the design of explosion venting devices has to be according to the EN standards. Other calculation methods, guidelines, standards can be used if these calculation methods are based on either published or experi­mental data that has been obtained from representative explosion venting trials.

The design of WinVent 3.1e is based on:
VDI 3673-2002:   Pressure venting of dust explosions.
Bartknecht, W.:    Explosionsschutz: Grundlagen und Anwendung,
                               Berlin, Heidelberg, New York: Springer 1993.

The new standards EN 14491-2006 and EN 14994-2007 are mainly based on VDI 3673-2002 and W. Bartknecht. Therefore the WinVent 3.1e corresponds still to the state of the art and can be further used..
