• B9106 Explosion Protection

    Many industries in which combustible dusts or gases are handled risk the devastating effects of an explosion. The amount of heat liberated during an explosion creates extremely high pressures which can result in damaged process equipment, loss of production and serious injury to personnel. Leading insurance firms estimate the average direct costs of an explosion in the hundreds of thousands of dollars, with many unprotected explosions leveling plants, or even closing businesses.

Data Sheet

  • X.1.26.01 Gas Cartridge Actuator

    The GCA consists of a 17-4 PH series stainless steel body containing two sets of bridge wires. This device is designed to operate by electrical input from a Fike system controller. Operation of the GCA occurs when the electric current is sent through the bridge wires causing an exothermic chemical reaction. This generates the necessary pressure to open the rupture disc and discharge the suppressant agent or pneumatically drive the gate closed on the isolation valves.

  • X.1.27.01 HRD Nozzle Assemblies

    High Rate Discharge (HRD) nozzle assemblies are mounted between the explosion suppression container and vessel wall. Nozzle assemblies are available in spreader, telescopic, and no-nozzle configurations. To equip an HRD suppression container for use, it is necessary to order a nozzle assembly and its compatible nozzle cover and bolting pad. Each part is sold separately to maximize design flexibility.

  • X.1.27.01 Suppression Dispersion Nozzles

    Dispersion nozzles are mounted directly to the agent storage container. These patented “Zero Restriction” nozzles do not add additional flow restrictions. In fact, the total area of the dispersion orifices is twice that of the nozzle inlet. In addition to the standard nozzle, Fike offers a flush-mount, telescoping nozzle for hygienic or abrasive applications.

  • X.1.28.01 Suppressant Containers

    Fike suppressant containers provide optimum performance in delivering chemical suppressant agent in suppression and isolation applications.

Application Profiles

  • EAP 1002 Product Drying

    In the production of powdered food or pharmaceutical products, one process step involves drying the product. This is commonly done by a fluid bed or spray dryer. Inherent to this process is the requirement to suspend the powder in air. The suspended powder may create a dangerous potential for an explosion and in cases where a flammable solvent or gas is present with the powder (hybrid mixture) this explosion potential is magnified.

  • EAP 1003 Dust Collection Systems

    Dust collection involves the removal, or collection, of solid particles from a flowing air stream, for the purpose of eliminating nuisance dust, the safety and health considerations of employees, product quality improvements, and the collection of powdered products.

  • EAP 1006 Protecting Spray Dryers with Explosion Suppression

    The powders produced from liquid feedstocks are suspended in the spray dryer at elevated temperatures presenting possible fire and explosion hazards. in the production of food or pharmaceutical products, there could also be residue solvents (hybrid mixtures), that increase explosion hazards.

  • EAP 1008 Bucket Elevators

    Bucket elevators are among the most common conveyors used for making vertical lifts of bulk materials. The materials being conveyed can vary over a wide range of sizes, from powders to pellets. Most of these bulk materials inherently produce dusty conditions within the bucket elevators, creating explosion hazards.

  • EAP 1009 Coal Pulverizer

    Raw coal is fed into the coal inlet, dried and ground to a fine dust on the grinding table. Hot air (inert gas) is used to pneumatically carry the coal dust upward through the classifier and into the transport pipe.

  • EAP 1010 Dust Collector

    A dust collector (bag house) is typically a low strength enclosure that separates dust from a gas stream by passing the gas through a media filter. The dust is collected on either the inside or the outside of the filter. A pulse of air or mechanical vibration removes the layer of dust from the filter. This type of filter is typically efficient when particle sizes are in the 0.01 to 20 micron range.

  • EAP 1011 Cyclone

    Dust laden gas enters the chamber from a tangential direction at the outer wall of the device, forming a vortex as it swirls within the chamber. The larger particulates, because of their greater inertial, move outward and are forced against the chamber wall. Slowed by friction with the wall surface, they then slide down the wall into a conical dust hopper at the bottom of the cyclone. The cleaned air swirls upward in a narrower spiral through an inner cylinder and emerges from an outlet at the top. Accumulated particulate dust is deposited into a hopper, dust bin or screw conveyor at the base of the collector.

  • EAP 1012 Electrostatic Precipitator

    In an electrostatic precipitator, particles suspended in the air stream are given an electric charge as they enter the unit and are then removed by the influence of an electric field. A high DC voltage (as much as 100,000 volts) is applied to the discharge electrodes to charge the particles, which then are attracted to oppositely charged collection electrodes, on which they become trapped.

  • EAP 1013 Storage Bins

    In an electrostatic precipitator, particles suspended in the air stream are given an electric charge as they enter the unit and are then removed by the influence of an electric field. A high DC voltage (as much as 100,000 volts) is applied to the discharge electrodes to charge the particles, which then are attracted to oppositely charged collection electrodes, on which they become trapped.EAP 10

  • EAP 1014 Dust and Pipes

    Transport pipes and ducts are enclosures that move coal dust from one piece of equipment to another, or that brings heated gases into the equipment for process operation. These enclosures can range from lightweight sheet metal to heavy wall pipe. They can be round with diameters up to approximately 5 feet, or rectangular with cross sections up to approximately 2’x3’

  • EAP 1016 Explosions in Cement Plants

    Cement manufacturing is one of the largest mineral commodity industries in the United States, with an estimated production capacity of greater than 73 million metric tons annually.

  • EAP 1018 Cyclone and Dust Filter

    Most manufacturing processes require the removal or collection of dust particles, whether that is eliminating nuisance dust or collecting powdered products. After removal or collection of dust particles, the solid particles typically must be separated from the flowing air stream. One method of separating the solid particles involves using a cycling and dust filter (see figure on page 3). Heavier dust particles are first separated from the air stream into the cyclone through centrifugal forces, then the smallest particles are separated from the air into the dust filter

  • EAP 1020 Elevator Silo Filter

    At an elevator facility, a truck unloading system is used to move grain from the truck into storage silos. While conveying grain throughout the system, fine dust will become airborne creating a risk for dust explosion in practically every process section: (see Figure on page 3 from left to the right) truck unloading hopper, bucket elevator, silo and dust aspiration/filter system.

  • EAP 1004 Pulverised Coal Systems

    The pulverisation of coal to improve burning efficiency and maximize energy output is a method that has been used for more than 75 years.Pulverised coal processing and storage systems are typically found in power generation, steel and iron manufacturing, cogeneration, cement drying, and other industries that employ injection furnaces.

  • EAP 1005 Protecting Dust Collectors with Explosion Suppression

    The nature and operation of dust collection equipment present possible fire and explosion hazards, due to the greater concentration of small particle material. Dust collectors experience more explosions than any other process vessel types.

  • EAP 1017 Cement Kiln

    A cement kiln is the world’s largest moving manufacturing machine. Cement kilns are cylindrical ovens, some as long as 1000 feet and as much as 24 feet in diameter. They rotate one to three times every minute. The kilns are mounted at a slight incline. The inside is lined with fire resistant brick. Powdered coal, oil, gas, liquid waste-derived fuel, and solid waste fuel are used to fuel the kiln. Raw material enters the kiln and is heated to over 2700°F. The material leaving the kiln is called clinker.

  • EAP 1019 Manual Fill Hopper

    This process includes a hopper for manually feeding product into a powder handling plant (see figure on page 2). Filling of product hoppers can cause dust particles to become agitated and suspended in air. This dust laden atmosphere can then support a deflagration if an ignition is introduced. A dust collector is installed onto the hopper to pull vacuum, which in effect limits the amount of dust that will become airborne both inside and outside the hopper when feeding the product.

  • PHEP 001 Bus Network Technology

    Fike introduces the use of bus network technology to the explosion protection industry. Fike’s explosion protection control system uses bus network technology to exchange information between its components, and to “connect” protection controllers to ‘enlarge’ the protected area if required.

  • PHEP 002 Eplosion Pressure Detectors

    Single detection is sufficient for most applications, however paired detection is an option dependent on customer preference (some users have a tradition of using 2 detectors in tandem at each detection point (location) or 2 detectors may be required to achieve a stable working system for specific high demanding applications (see ‘paired’ below).
