Optimising production line maintenance for gas burners

WHENEVER flow of gases needs to be adjusted or monitored, Kobold, represented locally by Instrotech, has a model of UTS, which it is positioning as a “practical and affordable” variable area flowmeter for monitoring gas burners.
“This compact measuring instrument can be placed at various locations, precisely where required,” the company said in a statement.
Recently it was tasked with optimising gas burner production line monitoring in order to achieve a ‘No Product Rejection’ status.
Lighting machine manufacturers generally require several small and one large annual maintenance session on their production lines. This means shutting down (completely dismantling) the production lines. All failures need to be fixed, broken or worn parts replaced, burners and valves refurbished and production lines reassembled.
It is only after such maintenance, that production restarts. Each production phase of the renewed line must be re-sync’d, each burner reset at the correct temperature and the entire production process adjusted in order to manufacture the highest quality product.
“This requires not only precision but is time consuming and involves a significant quantity of reject product. The time consumed and the wasted goods costs money, increasing the final product cost and, also may result in a serious competitive disadvantage in the market.”
The Kobold solution was to equip production lines with UTS type variable area flow meters.
“One UTS is built into each gas circuit for gas burner control. Retrofitting of machines without major modification even with 10-20 flow meters is easy due to UTS’s compact design and small footprint,” the company said.
“When production line produces a perfect product, the displayed values of the instruments are recorded.”
Following the next shutdown of production lines and before starting the conveyor-belt, all burners are set up to the value recorded by UTS. “It takes only a few seconds to then set each burner. Users could re-start continuous production in a short time, as the quality of first finished product will be perfect.”
According to the company, the total investment is returned after only a few maintenance cycles. Typical examples include monitoring supply to gas burners or engines and the supply of laboratory equipment with different gases.
