The first step is to evaporate water and generate steam. The combustion system and steam boiler must be appropriately matched. As early as 1964, MARTIN directly integrated the steam boiler into the combustion system in the Rotterdam and Paris – Issy-les-Moulineaux – plants. This concept was further developed and used for WTE plants worldwide.
