The solution was based on FFE’s Talentum flame detectors and a high-pressure watermist system from Hydramist©. The complete system was designed and installed by FFE contractor Fireworks.
Each conveyor was divided up into fire zones, with each zone having a dedicated Talentum flame detector, zone valve, fire control panel and set of water pipes and spray nozzles. The flame detectors and nozzles were installed inside the conveyor covers to provide optimum protection of the biomass. The watermist system operates from a central high pressure pump set with 100% redundancy.
The entire system was then linked to a side-wide addressable fire panel which allows further automatic controls to be programmed, ensuring the desired number of zones will automatically operate when required and that the conveyors will stop as soon as the fire system operates.
Fireworks trained E.ON staff to operate the system and carry out fault-finding and remedial actions if required. The entire system requires minimal maintenance and is on constant standby 24 hours a day when the biomass handling depot is in operation.
“FFE’s Talentum optical flame detectors are ideal for this type of application. By utilizing infra-red (IR) sensing technology, they detect flames within seconds, irrespective of any dust, steam or smoke present.With the addition of an ultraviolet (UV) sensor the detector also becomes immune to false signals such as sunlight,” commented Dr Daniel Waldron, a research scientist at FFE.
FFE is a UK-based, global design and manufacturing business, dedicated to supplying specialist detection products to the fire industry. The company’s two leading brands are the Fireray optical beam smoke detector, with over half a million units installed worldwide, and the Talentum flame detector, one of the world’s most respected flame detector brands. FFE also leads the global market in providing fire extinguishers for aviation use and produces a range of vibration switches for industrial applications. It is a Halma Company.
