Application of Modified NiCrMo Alloy Systems for Boiler Tube Surface Protection in Waste-to-Energy Environments
Internationally, Waste to Energy and Incineration markets continue to grow in capacity as fossil fueled facilities decline and nuclear generation is curtailed. With this comes a greater need to burn more corrosive materials combust at higher temperatures and extract more energy. The reliability burden that this places on operators of plants is re-opening opportunities for thermal spray solutions as a cost effective solution for boiler tube protection. Where maintenance costs, opportunity costs and access restrictions may preclude alternative in-situ technologies, thermal spray technology may fill a gap in providing new reliable and flexible process and materials technologies for both mid- and long-term protection of water wall and superheater tubes. While historically thermal spray coating solutions have had a spotty record in waste to energy environments, advances in both process and materials technology specifically for WTE environments is such that coating performance now approaches the performance of high alloy wrought materials. This is verified through accurate laboratory modeling and scale tests and trials conducted by OEM’s and plants.
The need for incineration capacity for waste materials, whether from municipal solid waste or from industrial waste requirements has increased as a result of zero landfill andprogressive recycling policies. For many European and Japanese markets waste incineration is the only viable alternative to previous methods of waste disposal. The European Union Landfill Directive (1999/31/EC) specifically precludes certain materials such as hospital waste, tires, and certain reactive and flammable materials from land filling.

New Waste-to-Energy Facility Energy Works Hull, United Kingdom
© Thomé-Kozmiensky Verlag GmbH (9/2016)
Energy Works Hull (the Project) is a milestone project for the UK’s waste and renewable energy sector. It will be one of the largest gasification facilities receiving MSW in the UK, indeed in Europe. It is one of the first advanced conversion technology Projects to receive its renewable electricity subsidies through a Contract for Difference, the mechanism by which the UK Government determined to move from Renewable Obligation Certificates following its Electricity Market Reform process. It also plays a significant part of the urban regeneration of the City of Hull. The level of community engagement and benefit has resulted in the project receiving a GBP19.9M grant from the European Union’s Regional Development Fund.
Resource Recovery from Waste Using the Input Flexibility of Waste Gasification Technology

Nowadays, gasification of waste or biomass is becoming the great interest all over the world. Especially, gasification of municipal solid waste (MSW) has been well-researched in Japan. The development of MSW gasification technology was started in the 1970s in Japan because of oil crisis. Several technologies have been researched and developed. The Direct Melting System (DMS), which is the gasification and melting technology developed by Nippon Steel & Sumikin Engineering Co., Ltd., is one of the developed waste gasification technologies in this era. This technology was introduced for commercial use in Kamaishi City, Japan in 1979. As well as this waste technology, other gasification technologies have been developed for commercial use and installed.
bifa-Text Nr. 57: Die Abfallwirtschaft im Jahr 2030 - Eine Szenarioanalyse nicht nur für Bayern

In einer neuen Studie des bifa Umweltinstituts werden mögliche Entwicklungen der regionalen, nationalen und internationalen Rahmenbedingungen für die bayerische Abfallwirtschaft im Jahr 2030 dargestellt sowie deren Auswirkungen auf die Abfallwirtschaftsstrukturen und auf die Ökoeffizienz. Das Projekt wurde im Auftrag des Bayerischen Staatsministeriums für Umwelt und Gesundheit durchgeführt. Die Ergebnisse bieten auch anderen Behörden, Unternehmen und Verbänden in Deutschland eine Basis für die eigene Positionierung und Strategieentwicklung.

Enhancing of the Energy Efficiency of an Existing Waste Incineration Plant by Retrofitting with a District Heating Network
© Thomé-Kozmiensky Verlag GmbH (9/2016)
The German Cycle Economy Act (Kreislaufwirtschaftsgesetz KrWG) and discussions on the turn of local energy policies led to intensive examination of options for optimising utilisation of heat produced by the waste incineration plant (MKW) in Weißenhorn. This has been carried out by the waste management firm(Abfallwirtschaftsbetrieb – AWB) of the district of Neu-Ulm over a long period of time. This was also prompted by knowledge that utilisation of already generated energy in the form of combined heat and power generation (CHP) is one of the most efficient ways of achieving climate protection targets. This results from considering which courses of action are available for climate protection.
