Description

Background information Helsinki Parish Union is planning to build a new electrically powered crematorium at Malmi Cemetery. The crematorium will serve both the residents of Helsinki and the entire population of the Helsinki metropolitan area. At present, Helsinki Parish Union cremates approximately 5,000 deceased persons per year, and it is likely that the number of cremations will increase in the future. Helsinki Parish Union has two separate crematoria at Malmi and Honkanummi cemeteries, and cremation work is mainly carried out in two shifts. Approximately 5,000 cremations will be carried out annually at the crematorium. For the new crematorium, the authorities will require emission levels that necessitate flue gas cleaning equipment and the use of best available technology (BAT). In all other respects, the equipment must comply with the HELCOM emission limit values: https://helcom.fi/wp-content/uploads/2019/06/Rec-29-1.pdf In relation to temperature, the equipment supplier will be required to provide documentation approved by the environmental authorities concerning, among other things, the furnace combustion temperature and its effects on both the combustion process and emissions. Questions to the RFI: Furnaces and flue gas cleaning equipment 1. What kinds of electric furnaces do you offer? 2. What is the structural design of your electric furnaces, and can a furnace be installed on site as a ready-made modular package, or is it constructed on site? 3. In your furnace, is the coffin inserted from a different end from that at which the ashes are shovelled? Is the shovelling of the ashes carried out automatically by brushes, or manually by the crematorium operator? 4. On average, how many cremations can be carried out with one furnace during an eight-hour work shift? 5. What kind of electrical power input does the furnace require? 6. What types of flue gas cleaning system that comply with HELCOM emission limit values do you offer for an electric crematorium? Can you provide certification of your equipment’s emission values? If your equipment does not comply with HELCOM values in certain respects, for example in relation to combustion temperature, can you provide documentation confirming approval by an environmental authority? If you already have such documentation, please attach it to your response. 7. What type of technology is used in your flue gas cleaning systems, for example cyclonic, activated carbon or fibre filtration? What operational and seasonal maintenance measures do they require? What kind of waste do they generate, and how should that waste be handled appropriately? Information systems 8. What kind of information systems (software) does your flue gas cleaning equipment use? Are the cremation furnaces controlled using the same software, or how is software compatibility with furnace control ensured? Does the software include 24/7 support services? Can the software be supplied in Finnish? Heat recovery and electricity generation systems 9. What kind of heat recovery or electricity generation systems (e.g. ORC equipment) that can be connected to the flue gas cleaning equipment do you offer? What requirements do these systems have for connection to the building’s heating system, the district heating network, the cooling system for cold storage rooms, or electricity generation equipment? 10. In your opinion, what is the most cost-effective and impactful way to recover heat and reduce flue gas temperature? Questions relating to all equipment / systems 11. What space requirements do your equipment / systems have (e.g. height, width, length, weight and any other requirements relating to space and installation, taking into account operation and maintenance)? 12. What is the delivery and implementation timetable for the equipment, and is installation work included in the overall package you supply? 13. Do you offer maintenance agreements for the equipment, and what is their typical duration? What is the maintenance response time? Where are maintenance personnel and spare parts sourced from? What warranty terms apply to your systems? Other matters 14. What expertise do you currently have for implementing the project, and can the necessary other expertise be acquired e.g. via subcontracting? What references do you have over the past five years regarding the design and implementation of electric furnaces and flue gas cleaning equipment? 15. What are the biggest risks in the project, and how could they be mitigated?
