Royal Darwin Hospital Contract Report Case Study
As part of a larger infrastructure upgrade project at Royal Darwin Hospital, CCM Energy Solutions were elected by the primary contractor (O'Donnell Griffin) to supply two new Limpsfield high-efficiency burners for the two main John Thompson boilers which provide steam to the hospital. In addition, new Autoflame Mk7 combustion control systems were incorporated into the design, along with in-situ Autoflame exhaust gas analysis units for real time combustion analysis and combustion 'trim', and a data transfer unit to allow communication between the burner control systems and the hospital's building management system (BMS). Variable speed drives (VSD) were also to be supplied for the control of the forced draft fan blower motors.
Details
This aspect of the project was expected to deliver a payback period within two years following completion -this figure was based on calculations made during the pre-tender scoping process by AECOM, the consultant contracted to perform the work by the Northern Territory Government (Department of Infrastructure).
Installation & Commissioning
The old burners and associated mechanical controls were removed in full, along with the redundant control systems from the existing control panels. All mechanical and electrical work during this phase of the project was carried out by the boiler service company on site at the hospital (AirDucter), with oversight from O`Donnell Griffin and Royal Darwin Hospital. The first burner was successfully installed and fully commissioned by 8 March 2013, with the second burner being completed by 19 April 2013. All mechanical and electrical work was completed by the local regular boiler service company (who are based on-site at the hospital). Once this had been completed, CCM Energy Solutions attended site and undertook full field testing and then oversaw the commissioning process. The burners were then commissioned (firing on diesel) with the following combustion characteristics throughout the firing range (low to high fire):
- 02 levels in the range of 2.5-3.5%
- CO levels at sub-10 ppm and
- C02 levels in the range of 13-15%
- Efficiency levels between 86-89%
