Scope of FTL Equipment:
2no. FTIII (bariatric size) cremator, connected to an existing Double Flow Mercury Abatement Plant, uninstall Danstoker boiler and retrofit 2 no. compact coolers, Automatic Coffin Loader, High Speed Cremulator and Ash Transfer Cabinet, major building works to a listed building and utility infrastructure upgrades. Supported with a long term all inclusive service agreement for 15 years
In Jan 2020 FTL were awarded the contract to install 2no FTIII cremators, compact coolers and ancillary equipment at an existing onsite location at Stonefall Crematorium. As this was an existing operational site, FTL had to carry out a multi phased install to make sure the site remained able to operate as per normal on a daily basis, with only minor disruption throughout the entirety of the programme. The project was particularly challenging even without working around Covid working regulations, this being due to the location of the existing cremators which could not be easily replaced either by site building or factory built without major building works. FTL were responsible for all works on site being Principle Contractor, and performing all CDM duties.
To enable the removal and controlled disposal of the existing 2no. Evans Universal 300/2 cremators FTL delivered and installed one containerised FT3 cremator, supplied within a specially adapted 20ft shipping container (this can be seen to the right of first photo). The container was placed external to the crematory within a compound- the unit was connected to the building with a temporary weatherproofed purpose-built corridor so enabling the externally located containerised cremator to be coffin charged from within the crematory. Once this containerised cremator was functional and site was cremation service secure, FTL could isolate and segregate the old cremators and begin the multi phased controlled removal and disposal.
Stonefall crematorium was an upgraded site that would house 2 new Single ended FTIII cremators, Compact Cooler Boilers all reconnected onto an existing Double Mercury Abatement system, FTL3 Loader, High Speed Cremulator (HSC), Ash Transfer Cabinet (ATC) utilising a new mezzanine space for maintenance, servicing and plant support.
Following awarding of the contract the design, procurement and manufacturing phases were undertaken. FTL attended monthly meetings with the client (HBC) and the clients’ consultants (NPS). During these stages, before site work commenced, designed designs were generated and discussed at end with client and architect, and on completion of design phase, the proposed final design was agreed and signed off by client. Unfortunately, the COVID pandemic struck the week prior to site establishment. Following discussions with client it was agreed that FTL would return to site (once Covid restrictions allowed) and begin works once a watertight building shell had been erected to store the equipment scheduled for delivery. FTL and NPS were in constant contact throughout this process so that the multi phased builders work could be completed and make the phased installation work for each specific stage. An external stone wall was removed in order to facilitate factory built cremators to be supplied so as to minimise FTL time on site. This was a complex task, performed by qualified stone masons, and due to planning requirements, the stone removed was all numbered and replaced
In May 2020 at the height of a worldwide Covid pandemic FTL commenced work on site, installing the 2no. FTIII Cremators initially, as ancillary equipment was to be erected around the 2no cremators whilst also in some cases utilising the cremators as structural support framework, this included both Compact Coolers (heat exchange boilers) located at high level as well as mezzanine framework which itself supports 2no. sets of coanda/combustion fans + frames. A 90 Tonne crane was used to offload all heavy plant, equipment and ancillary as well as aide in the preliminary mobilisation of the aforementioned plant and equipment.
After all the main plant and equipment had been delivered to site our team of installation engineers position, erect, and connect all mechanical elements of the supplied equipment, including all the flue gas ductwork from the FTIII’s to the Mercury Abatement system, chimney flues and compressed air pipework service. During the previous design meetings NPS and FTL had agreed and defined the installation’s flue gas ductwork routes etc. assuring that no service clashes were seen at the installation phase.
The next phase of works involved the installation of the heat-exchange water pipework circuit as well as integration of said pipework with the Air Blast Cooler, this was outsourced to Waites Mechanical Services Ltd who specialise in mechanical installation and are generally used for all our installations. Site visits were made in order to design the pipework routes and address enabling works to enable FTL to interface with the builders works from the start of the project.
Building and enabling works generally consisted of wall and roof penetrations to allow for equipment installation, having this completed pre-install, aids in less lead-time and prevents the project from drifting whilst also mitigating any unforeseen hurdles. The building contractor (Woodgreen) was also programmed around the cremation installation to perform the client specified building works, remodelling works and redecoration works and reforming the external stone wall to crematory. To utilise the waste heat produced by the new cremator abatement process, our site works also included the installation of a dedicated heat recovery module (plate heat exchanger) for the client to connection to the crematorium’s domestic central heating and hot water system or an alternative system at some future date.
Following on from our initial mechanical engineering installation, FT engineers then performed the electrical works on site, wiring up all the equipment. On this site in particular, the electric mains power supply into the building was inclusive of FTL’s remit to install, as per the tender’s scope of supply. FTL’s scope of works includes the supply of electrical power from the buildings incoming isolator to the 2no. FTIII cremator panel and Mercury Abatement Panel, these electrical works were performed using certified installation engineers, to regulation and all works fully certified thereafter. Once again communication between FTL and NPS was necessary to avoid electrical works and cable tray clashes with proposed building services future equipment were avoided.
Once all flue gas ductwork was installed and in place all duct and water-pipework runs were insulated and clad. This is outsourced to Powertherm Ltd, a specialist insulation installer who attended site prior to works so as to enabling the fabrication of pre-measured materials to insulate all exposed ducting pipework. FTL issue all flue gas ductwork drawings to the contractors to assist with any pre-work to be carried out prior to install.
Once all these phases have been complete, FTL take this opportunity to carry out and perform any snagging works which may need addressing, to ensure the product supplied is to the satisfaction of the end customer.
All the above-described works were performed in a single continuous multi phased programme with respect to the client’s project programme, and the crematorium was kept operational throughout the works on site. This was a very challenging site, but cremation services were maintained.
As a final installation stage, FTL commit our specialist commissioning engineers to perform all commissioning checks to an inhouse commission protocol, all steps logged electronically, and form part of the handover documentation. Once FTL have fully verified and logged all the aspects of the installed equipment and it is proven to be functioning correctly to the necessary required standards our commissioning engineer can start up the cremator and commence our formal on site staff training protocols.
Our formal training consists of a formal electronic tablet-based training course with which our commissioning engineer mentoring the operators via a step-by-step course in which we illustrate pre-heating the machines, getting the equipment up to operational temperature and generally operating the cremation equipment in a variety of operational scenarios. Training also covers the operation of supplied ancillaries such as the HSC and ATC. Additionally part of the training also covers in house maintenance including how to contact FT Technical Support and even covering how to perform simple maintenance tasks such as fitting spares and consumables (supplied by FTL) should they need replacing in the future.
Upon completion, a handover meeting is scheduled as to where the client will sign a handover certificate, confirming they and all other relative parties are satisfied with the product, allowing the project to draw to a close.
This is now a fully operational site.
