A closer look at BS&B's Explosion Venting IQR System

What is your product/technology?

BS&B Safety Systems has launched a bespoke explosion venting system for the waste management sector based on established systems developed for other industries. The Explosion Venting IQR System is designed to protect process equipment installed indoors, intercepting flames and quenching them to provide a safe environment for personnel.

How does it work?

Any industry which handles fine organic dusts is at risk of these materials burning and exploding. The explosion vent works by responding to the rapidly building pressure of an expanding fireball, opening to relieve the pressure. As the developing fireball passes through the explosion vent, it is intercepted by a quenching module.

A three-dimensional stainless steel precision mesh, retained by a frame, stops the flames. This quenching module also absorbs the pressure and temperature of the flames and retains potentially toxic burning dust.

While the temperature of a dust explosion can typically reach 500 °C, the IQR quenching module typically remains below 100°C, rapidly cooling down further due to its large surface area.

Where would it ideally be used?

The product can be used in all sectors of waste management including the biofuels industry, recycling plants and in industries where there is wood waste e.g. from shredding or pelleting.

How is it different?

The Explosion Venting IQR System follows the latest industry standards and is designed to meet the requirements of modern industry practices.  It is recognised by industry codes and standards relating to fire and dust explosions including NFPS 68, NFPA 654 and the European ATEX directive, and eliminates the possibility of a secondary ignition and subsequent explosion.

BS&B also differs from many other explosion protection companies as it provides active systems for both explosion protection and prevention, which can be used in tandem.

What benefits does it offer? 

By investing in explosion protection, organisations can protect themselves economically, follow appropriate health and safety standards and protect workers from potential risks. The effects of accidental fires or explosions can be devastating in terms of lives lost, injuries, damage to property and the environment, and to business continuity.

Where it has been used?

The system is used by a wide range of industries where combustible materials are handled including waste management, wood and furniture production, building suppliers, food manufacturers and solids and bulk handling sectors.

Cost?

Price depends upon the number of locations where the system is required and the size of the process equipment which requires protection.

Any savings?

A fire or explosion within a plant can cost organisations millions. The system protects organisations financially as it eliminates secondary ignition and subsequent explosion external to the protected system. Company employees are protected by providing safe working conditions.

Production schedules are safeguarded, minimising downtime and protecting market share. The system can also lead to a decrease in insurance premiums.

What about maintenance?

Minimal servicing is required as it is a passive safety device, but annual inspection is recommended by trained personnel. BS&B provide a range of support to users including 24-hour technical support, installation service and training, specialised testing and plant audits. Should the system be activated, there is minimal external clean up compared to an open vented dust explosion. The IQR system can typically be refurbished after activation for quick and economic process restart.

What is its life span?

If the system is kept well maintained and serviced annually then it will be operational for many years.

How is it future-proofed?

The system conforms to current European Union legislation, under the ATEX Directive 94/9/EC. Directive 94/9/EC provides the current technical requirements to be applied and the relevant conformity assessment procedures before placing equipment and protective systems intended for use in potentially explosive atmospheres on the European market.

How many have you sold and where?

The Explosion Venting IQR system is sold all around the world into a wide range of industries, but the waste recycling industry is showing the largest growth in terms of industry sales and installations. 

Anything else?

We can offer site demonstrations of our explosion protection and prevention systems and we always present our products at the Resource & Waste Management (RWM) Exhibition.
