BETE Fire Protection Nozzle Experience Water Deluge A customer was designing a water deluge system to protect an 11' x 40' x 8' high chemical tank. They needed complete coverage from 2 headers running parallel to the 40' long side.

BETE Applications Engineers provided several spray trajectories and the N series

was recommended because it offered the proper combination of coverage and droplet size, as well as industry approvals, such as Factory Mutual and UL.

BETE N series fire protection nozzles are recognized across the petroleum and chemical processing industries as the

first choice in dry, fixed fire suppression systems. BETE N series nozzles are used routinely in dry fire protection systems protecting offshore drilling rigs, LPG tanks, and LNG tanks, as well as other types of vessels containing flammable liquids.

Marine BETE N series nozzles are Factory Mutual and Lloyd’s Register approved for fire protection, a requirement for operation out of U.S. ports. These nozzles are used on ships with water systems, often replacing older CO2 based systems. N series nozzles are also used to protect outdoor escape routes onboard tankers and offshore oil-drilling platforms. Predicted spray patterns and trajectories provide estimated nozzle coverage under various wind conditions. Using this data, our customers are able to determine

the correct nozzle mounting locations.

BETE has supplied “Deck Edge” nozzles for U.S. Navy applications. The 3/4" NF300-80X and the 3/4" NF300-80 have been used in spraying Aqueous Film Forming Foam on the decks of aircraft carriers.

The 1/2" TF29-180 was developed for Navy magazine sprinkling on ships; it meets Military Specification MIL-S-24660 (SH). The 180° full cone pattern reduces the vertical clearance required between sprinklers and ordinance from 18" to 4".

Requirements for thermal radiation screening for personnel protection on ships have been met most effectively with the TF170 or TF150 series nozzles. The TF nozzles provide better absorption of thermal energy and dissipates the heat and energy from the fire. The multiple concentric cones provide a barrier to air reentering the fire while also minimizing spray wind drift.

Tunnel Fire Protection BETE Applications Engineers supplied spray pattern trajectory data for the fire suppression system in the 1.8 mile long Burnley Highway Tunnel in Melbourne, Australia. The data included different wind velocities to ensure that the nozzles specified

would offer sufficient coverage over a number of different wind velocities in the tunnel to control a fire. The system uses a combination of BETE N7W and N8W nozzles constructed in type 316 stainless steel.

In March of 2007, a serious auto accident occurred that resulted in a fire in the tunnel. The sprinkler system was activated and BETE N series nozzles succeeded in controlling the fire.

Water Wall A customer was developing a new water wall protection system on an oil rig to protect equipment and personnel from the extreme heat generated by the natural gas flare. The current system consisted of a few nozzles on the flare boom, but was inadequate for the amount of heat generated.

BETE Applications Engineers suggested a wide angle spiral would be appropriate, specifi-

cally, the N5W to match the specified flow rate. To confirm spacing, BETE modeling software was used to determine spray coverage trajectories from each nozzle when sprayed horizontally outward. These trajectories provided the customer the confidence that the new design would be more than sufficient to protect the rig.

BETE Product Performance Water Wall – Water is used as a barrier to shield against radiant heat, harmful gases, and flames to provide protection for personnel and equipment.

Nozzles: TF29-180, SRWM, in addition to water wall and water deluge nozzles

Nozzles: TF150/170, N, FF, NF

SRWM – pop-up operation for deck cooling/protection/decontamination; used where a permanently exposed nozzle would be an obstruction

TF150/170 – spiral nozzles with high flow rates, wide coverage in close proximity, multiple concentric cones; more effective than a fan

N – spiral with narrower angles than the TF150/170; regulatory approvals for fire protection applications

FF – provides a wide, single sheet spray with a 145°angle. Less effective cooling and barrier protection than spiral-type (TF, N) nozzles NF – greater choice of angles than FF (15° up to 120°)

Water Deluge – There are two general categories for water deluge fire protection systems.

1 Direct Extinguish - Large quantities of water are sprayed over the flames to control the blaze and extinguish the fire.

2 Cooling - Water is sprayed onto the exterior surface of vessels that are under pressure and/or contain volatile materials, cooling the vessel and preventing explosion. Nozzles: N, MaxiPass, TFXP, TF150, TFXPW, FF

N, TFXP, TF150, TFXPW – all spirals provide a spectrum of drop sizes with concentric rings of larger droplet, high momentum spray containing fine droplets between the rings. The high momentum, large drop rings punch through the flame while the smaller drops vaporize quickly, combining maximum flame penetration and heat transfer. This multiple cone strategy minimizes wind drift and prevents oxygen from reentering the spray area

N – spiral nozzle with advantages listed above plus tighter tolerances to meet insurance approvals. Protective blow-off covers available

MaxiPass – used when coverage diameter is more important than atomization and headroom is adequate. The MaxiPass produces larger droplets than an equivalent flow rate spiral causing improved wind resistance. High-pressure operation narrows the spray angle for greater penetration and resistance to crosswinds

TFXP – spiral nozzle with advantages listed above but with maximum free passage

FF – used for surface or equipment protection when relying on rundown for protection is acceptable

Marine – Marine applications include deluge, foam, and water wall systems where the nozzles are subject to extreme weather conditions and exposure to seawater.

TF29-180 – very wide coverage for limited headspace areas (such as storage rooms on ships)

Halon Replacement – Professionals are turning to fine water mist systems in lieu of environment-damaging Halon systems. Exceptionally fine water droplets are sprayed over the fire where they evaporate and displace the oxygen, extinguishing the fire. The low volume flow and high evaporation rate minimize water damage to sensitive equipment. Nozzles: MicroWhirl, L, PJ, P, MicroWhirl Head

MicroWhirl - high-pressure nozzle producing very low flow, extremely fine, misting protection

P, PJ – higher flows than the MicroWhirl; produces a very fine mist by means of an external impingement pin

L - higher flows than the PJ with fine atomization

MicroWhirl Head – standard, stock manifold for up to seven (7) individual MicroWhirl nozzles

Foam – The nozzles are used to spray low-expansion foam, such as AFFF, onto ship decks and in smaller enclosed areas to help subdue the fire. Nozzles: TF, N, NF, NFX

TF, N – spiral nozzles are placed so that the spray is perpendicular to the surface to be covered

NF, NFX – flat fan nozzles are oriented to spray parallel and very close to the surface to be protected

Tunnel Fire Protection – A well-

designed fixed fire suppression system in a traffic tunnel protects against loss of human life and minimizes structural damage in the case of a fire or explosion. Spiral nozzles can be more effective than traditional sprinkler systems due to higher flame penetration by the multiple cones. Nozzles: N, TFXP, TF150, TFXPW

N, TFXP, TF150, TFXPW – all spirals provide a spectrum of drop sizes with concentric rings of larger droplet, high momentum spray containing fine droplets between the rings. The high momentum, large drop rings punch through the flame while the smaller drops vaporize quickly, combining

maximum flame penetration and heat transfer. This multiple cone strategy minimizes wind drift and prevents oxygen from reentering the spray area N – spiral nozzle with advantages listed above plus tighter tolerances to meet insurance approvals. Protective blow-off covers available

TFXP – spiral nozzle with advantages listed above but with maximum free passage

Water Mist – Water mist systems use a finely atomized, low flow water spray to extinguish fire. They are ideal for protecting assets that would otherwise be destroyed by water damage in deluge systems.

Nozzles: MicroWhirl, L, PJ, P, MicroWhirl Head MicroWhirl - high-pressure nozzle producing very low flow, extremely fine, misting protection P, PJ – higher flows than the MicroWhirl; produces a very fine mist by means of an external impingement pin

L - higher flows than the PJ with fine atomization

MicroWhirl Head – standard, stock manifold for up to (7) individual MicroWhirl nozzles

Toxic Gas Mitigation – Water spray systems are used to remove water soluble, toxic gases from the air in the event of an accidental leak. These systems prevent the spread of hazardous vapor clouds. BETE TF16FCN and TF20FCN nozzles were chosen for mitigation systems of accidental releases of hydrofluoric acid (HF) by the Industry Cooperative Hydrogen Fluoride Mitigation Assessment Program. Nozzles: TF, TFXP, N

TF/TFXP - finer spray nozzles with standard flow rates; good for scrubbing chemicals N - spiral nozzle with advantages listed above plus tighter tolerances to meet insurance approvals. Protective blow-off covers available

Dust explosion protection – Water

spray systems are used to prevent explosive combustion triggered by dust build up or static electricity in storage tanks and transfer conveyors for items such as coal and grain. Nozzles: MicroWhirl, L, PJ, TF, SRWM

MicroWhirl, L, and PJ – fine mist with no wetting. Increases humidity and lowers static discharge risk

TF – adding enough moisture to prevent/ knock down dust

SRWM – installs flush to the vessel wall and extends when activated; used in extremely dirty or dangerous areas where an exposed nozzle would be destroyed
