23.04.2018 High-temp air cannon installation without production shutdown

Martin Engineering, Neponset, IL – with European had office in Walluf, Germany – has announced a new technology for installing air cannons without a processing shutdown.  The system allows specially trained technicians to mount the units on furnaces, preheaters, clinker coolers and in other high-temperature locations while production continues uninterrupted. Martin developed the patent-pending Core GateTM to reduce expensive downtime associated with traditional installation methods, which require that high-heat processes be halted to allow core drilling and mounting of the cannons.  The new system has been paired successfully with the firm’s Smart NozzleTM series, a family of air cannon nozzle designs which can be serviced or replaced during production, without removing the cannons themselves.  Currently the only technology to safely install air cannons and replace nozzles during production, the specialist equipment and process require no confined space entry.  With all installation and service performed from outside the vessel or process, the Core Gate system also contributes to a safer workplace by minimising the difficulty and hazards of installation and maintenance.
Replacing a conventional fan nozzle on existing equipment typically requires the removal of refractory material from around the nozzle opening, usually with a pneumatic hammer from inside the vessel.  The process invariably weakens the surrounding refractory and renders it more susceptible to spider-webbing and subsequent cracking.  In contrast, the Martin replacement system leaves the refractory undisturbed during service, and one worker can safely perform installations or maintenance from outside the vessel.
