PROBLEM SOLVED™ PAPER
SOLUTION:
Martin® Air Cannons with Martin® Retractable Nozzles
INDUSTRY: Cement
LOCATION:
Cement Plant in Southern USA
PROBLEM
The Plant produces over a million tons of cement every year. Due to
such large production volumes, material was building up on the raw
feed material inlet chute to the feedshelf in the preheat tower. The plant
was incurring unscheduled outages due to buildup/blockages, costing
tens of thousands of dollars. In an attempt to improve productivity, the
plant reached out to Martin Engineering to help increase efficiency and
eliminate emergency outages.
The nozzle extends to fire and then retracts to protect the
exposed tip from extreme heat.
SOLUTION
MartinPLUS® service technicians installed two Martin® Hurricane Air
Cannons with Martin® Retractable Nozzles in the build-up area where
existing air cannons could not dislodge material because of their
location. The additional two air cannons with retractable nozzles
provided 360-degree effective cleaning area. The nozzle is controlled by
one solenoid, and the nozzle weldment is serviceable from the outside
of the riser duct. The 360-degree nozzle is less aggressive, eliminating
damage to refractory from improper use of compressed CO2.
MartinPLUS® technicians installed two air cannons with
retractable nozzles to eliminate material buildup.
RESULTS
To date, the plant is satisfied with the addition of Martin® Hurricane Air
Cannons with Martin® Retractable Nozzles. They are not aware of any
build-up in the previously troubled area and therefore not experiencing
any emergency outages.
The Martin® Retractable Nozzle is used for hard-to-reach
locations in cement towers and other high-temp applications.
