Eccentric Flame Arrester

In-line eccentric flame arrester is designed for horizontal installation to achieve a lower pressure drop and avoid condensation on flammable gases that can condense at the lowest points of the installation. They are useful in biogas plants to avoid that the water vapor that contains the biogas from the digester can condense in the body of the flame arrester and be deposited in the lower part of the flame arrester, reducing its passage section. Its flat bottom prevents the accumulation of water, allowing gas to push the condesmands along the line. They can be installed to avoid detonations and/or deflagrations. They are usually installed together with sediment pots and traps that collect condensates from the line.

Our flame arresters comply with ISO 16852 standards, set out in the ATEX Directive 94/9 / CE. There are different types of flame arresters depending on the gas and the type of explosion. To ensure the integrity of the equipment to be protected, it is vital to correctly select the type of flame arrester.

For your correct choice you must know:
◆ The gas group of the mixture IIA, IIB or IIC
◆ The origin of the possible ignition point and the distance to the flame arrester
◆ Direction of the advance or the recoil of the flame

The PZHQ-B series of In line eccentric flame arrester is distinguished by its eccentric housing shape.
When condensate accumulates within the flame arrester unit, the design enables theliquid to drain without collecting large amounts in the housing.

The eccentric design of the device has decisive advantages in comparison to the classic flame arresters when pipes are intalled close to ground level.

Features:

● Eccentric design prevents the collection of condensate.

● The modular design enables each individual discs to be replaced.

● Easy maintenance with quick removal and installation of discs.

● Eccentric design allows installation in close to ground level.

● Bidirectional operation as well as any flow direction and installation position.

● Protects from deflagration and stable detonation.

● lnstallation of temperature sensors possible.

As National, provincial, and local governments air quality regulations become more stringent, incineration of gases becomes a more viable option rather than venting to atmosphere. In addition, there are regulations that require gas with any significant sour content be flared because of foul smell and toxicity. Companies that engage in this type of activity understandably have important safety concerns and protection against flashback in systems that contain flammable liquid products becomes a serious issue.

Flame arrestors have been utilised in a variety of applications over the past fifty years.In special environments, the In line eccentric flame arrester is an ideal choice.Old and new applications would include:

● Storage tank vents
● Offshore drilling platform vents
● Oil/petrochemical refineries
● Chemical Processing plants
● Marine loading systems
● Natural gas supply lines
● Flare stacks
● Pulp and paper NCG processing
● Vapour incineration systems
● Vapour recovery systems
● Landfill gas incineration
● Sewage treatment vapour processing
● Pharmaceutical
