Cardiff EfW

Cardiff Timelapse

Trident Park Energy Recovery Facility in Cardiff is now only a few months away from completion.

Once fully operational the facility will be handling 350,000 tonnes of residual waste, or post-recycling waste, per year, generating 28MW of electricity - enough to power around 50,000 households.  172 tonnes of that waste will be coming from five Councils that make up the Prosiect Gwyrdd partnership: Cardiff, Newport, Monmouthshire, Vale of Glamorgan and Caerphilly. 

LATEST UPDATE FROM SITE - 21 September 2014 @ 1540

The facility is currently in commissioning phase.    As part of that process we are currently conducting refractory dry out and boiler flushing.  This is a one-off process during commissioning only to ensure that the furnace can operate at the level required for operational conditions.  

This process has been completed on the first boiler (two boilers in total) and is currently underway on the second boiler.  Whilst the completion of this boiler was hoped for today, this has been slightly delayed and testing will continue into next week.

This procedure involves firing the burners using low sulphur diesel (<0.1% sulphur content) and slowly building the heat up within the boiler.   On reaching 350oC, the temperature is held for 24 hours, after which it is slowly reduced and the burners are turned off, completing the process.

This procedure may create a darkish plume of smoke from the stack. This is a normal part of the commissioning process only and will not form part of normal operations.

During this testing the burners heat up the boiler drum water and the water that circulates through the boiler walls.   At the current time the turbine and Air Cooled Condensers (ACC) are not in use, therefore the steam must be vented directly into the atmosphere and will be visible from the boiler hall zone of the plant.  This is also a normal part of the commissioning process and will not form part of normal operations.

The first delivery of waste has arrived on site and the first burning of waste is scheduled for Monday 29 September. Steam blowing is also planned for the end of September and is required to clean out the internals of the steam pipes following the construction process.  Steam blowing will also produce a visible plume of steam and can be a noisy process consisting of a loud rumbling noise.   The blowing process will involve a single blow each day (including the weekend) between 10am and 12pm lasting for approximately 15 minutes.

Steam blowing is also a standard and safe process that is part of the commissioning process only.   Exact dates and timing of the steam blowing will be published on this site as soon as they are confirmed.
