The King 7510 series of variable area flow meters brings both energy savings and quality improvements to leading brick and tile manufacturer in the UK.
Premier Control Technologies were asked to help in identifying a product that would ensure a balanced gas delivery to kiln burners. Our client had identified that during the manufacturing process there was gas wastage which was costly. Of equal significance there were inconsistencies with the curing process.
The environment was hot and had an atmosphere containing 0.75 ppm of Sulphur Dioxide, compatible materials were important. Each kiln had individual burners and it was necessary to ‘balance the burn’.
Due to the numbers involved (over 400) cost was a consideration. PCT suggested the 7510 series rotameter manufactured by King Instrument Company. It is not only robust but offers clarity; furthermore King offers a bespoke flow scale service, offering many volumetric flow units. We were able to supply a volumetric flow scale with the specific gas characteristics the application required.
The meters were positioned on the inlet to the burners along with a needle valve. The operator was then able to trim each burner by either increasing or restricting the gas flow. This ensured that the flame quality was optimised and that the temperature was maintained evenly over the kiln.
The savings in terms of energy cost and yield more than justified the investment.
