Babcock Wanson energy centre cuts Kodak bills by 18 per cent 19 December 2012

Kodak's new energy centre, which is based on a Babcock Wanson UK ESM8000 steam generator, is now delivering 18% energy savings at its Harrow plant in NW London.

The new plant – launched by Kodak as a project in 2011 – will take over from the site's combined heat and power (CHP) plant to reduce energy consumption at weekends and other periods of low demand.

Kodak CHP plant, which is based on a 50-tonne water tube boiler, was built during the heyday of film processing, so is is sized for a historically much larger factory operating seven days a week.

The new steam generator has been designed to supply 8,000kg/h of steam to maintain the steam service for non production needs, allowing the CHP plant to be switched off at the weekend and restarted on Sunday night.

As space in the existing boiler house was at a premium, Babcock Wanson designed a separate energy centre to house its coil type steam generator, which uses modern controls to maintain a close ratio between burner firing rate and water input, with inverter drive for both the combustion air and feed water pumps.

According to Abid Khalil, project manager for Kodak's paper manufacturing operations, Babcock Wanson's ESM was selected for its operating efficiency and quick Autostart facility, which can be controlled remotely from Kodak's main process control centre.

"The new plant set up has driven an estimated 18% reduction in total energy cost for the site," states Khalil.

"Reduced energy consumption is also driving a reduction in greenhouse gas emissions of NOx, CO and CO2," he adds.
