Automatic Control of Firing in a Brickmaking Tunnel Kiln. A Demonstration at Salvesen Brick (Manchester (GB))

摘要

At the Denton brickworks of Salvesen Brick, a computer control system retrofitted to two gas-fired tunnel kilns has successfully reduced energy consumption by 17.2% and increased output by 11.8%. The total cost of the installation was Pound 225,000 and the financial benefits accruing from it total Pound 167,000/year giving a simple payback period for the project of 1.35 years. The system was installed to provide automatic control of the kilns and to allow improved combustion conditions. Energy and cost savings were expected from lower firing temperatures, improved product quality and reduced staffing requirements. (ERA citation 11:056326)
