Regenerative Energie
High repair costs, outlay for flue gas cleaning systems and the stagnation of the waste availability are the challenges for economical operation of thermal recycling plants. Corrosion mechanisms in waste incinerators, biomass and alternative fuel plants are partly responsible for the high maintenance costs and require a series of measures in order to secure and increase the availability of the respective plants.
As is well known, thermal utilisation of waste in waste incinerators, biofuel and alternative fuel plants causes corrosion on the material qualities traditionally used, e.g. 16Mo3, P265GH, 13CrMo45, etc. In particular at high material temperatures, the elements chlorine and sulphur which are released in the flue gas cause extreme emaciation as a result of high-temperature chlorine corrosion and molten salt corrosion. The restricting of flue gas temperatures, the flue gas composition and the operating method can help minimise corrosion mechanisms. However, this makes it impossible to increase the level of efficiency and thus improve electricity production and at the same time it does not make for a clear reduction of damage. It is therefore imperative to take measures on the material side. As well as other measures, the method of weld cladding has emerged - this method makes it possible to increase corrosion resistance whilst still utilising the benefits (strength, weldability, formability and price) of traditional steel materials. The following chapters describe different individual weld cladding methods and constructional options, and the specific advantages and disadvantages are explained.

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
