REPLACEMENT OF BURNERS

Replacing burners is done without stopping the production, the burners are replaced one by one and it takes half a day, max 1 day.
In this case the exisitng burners were removed on ‘day 0’, the new burners installed on ‘day +1’, in the mean time no glass was coming in.
The job was done by the factory’s personnel.
On ‘day + 1’ the burners in the first 3 sections were replaced.
Our engineer supervised the job.

GAIN IN CONSUMPTION

For every first installation we make a study (for free) of the client’s situation and calculate the possible gain in consumption for the running article.
We visited this factory 3 months before but could not calculate the possible gain in consumption due to the mix Antonini – Weishaupt.
The factory decided nevertheless to replace the Antonini burners taking in account the results realized with our burners in the other lines.
We were surprised by the result 46 % gain (same article) but it probably is because Antonini burners are not designed to be used in CNUD lehrs.
Also, our burners give the possibility to measure and adjust the ideal gas / air ratio, resulting in a gain varying between 0 and 7 %.
When calculating the payback time of the investment, the price of the CO2 rights should also be taken in account.

RELIABILITY OF G-LEHRS BURNERS

Our burners practically never go in alarm, a week without an alarm is the norm.
If necessary, restarting is done at a push of the reset button or via the central supervising system.
The burner does not need to be dismantled for inspection or repair, replacing electrodes is extremely simple and does not require disassembly of the burner.
Cleaning the fan or other parts has never to be done.
We have no real explanation for this, it probably is because our burners close the connection to the tunnel when the burner is not burning, no hot air flowing in or out.
The maintenance staff always tells us that they are extremely satisfied with our burners, no alarms, no breakdowns, no maintenance.

MAINTENANCE

The burner does not need to be dismantled for inspection or repair, replacing electrodes is extremely simple and does not require disassembly of the burner. Cleaning the fan or other parts is not necessary because we close the connection to the tunnel when the burner is not burning.
It is the hot air flowing out when the burner is not burning that makes the fan dirty or leaves smooth on the torches.
The maintenance staff always tells us that they are extremely satisfied with our burners, no alarms, no breakdowns, no maintenance.
