scope:

In the practical example used in this standard two thermal waste incineration process plants both with grate firing are compared. The consideration of both technologies (at various stages of development) preserves the objectivity of the comparison, as both procedures are treated equally. A serious evaluation of this type can only take place under the concrete framework conditions of the individual case. The two units under consideration essentially differ in target energy (electricity and/or heat) and in flue gas treatment.

The operational data required for the evaluation, e.g., thermal power, operational availability, air to fuel ratio are based on existing units to make the example more realistic. However, particular requirements arose for the necessary information due to the demand to demonstrate the different assessment methods using the same example. These could not be fulfilled from the available practical data set sourced from just one actual plant. Therefore, data and information from different sources was compiled into one unified data basis. In the development of this standard, it was neither possible nor intended to give a representative overview of plant types or technologies. For this reason, the calculation results of this standard cannot be interpreted as actual statements on real units or typical waste management procedures. This standard focusses rather on the individual work steps including the necessary assumptions and the applied data, the calculation procedures for individual assessment methods in detail, and thereby draw attention to methodical problems and ways of solving them. This standard also demonstrates which types of statements can be expected from the different assessment and calculation methods. Overall, the practice- based demonstration of procedures, necessary prerequisites, and typical results of different methods in this standard offer additional assistance for those involved in waste management to help select a method for individual cases of application and to make themselves familiar with the execution of the chosen method.
