Steam capacities up to 600 t/h - steam parameters up to 570 °C, 170 bar.
Natural circulation steam generator in a compact design, largely prefabricated in the workshop. As a two-drum boiler in natural circulation design, prefabricated in modules. Steam generator in a natural circulation design with several vertically arranged boiler passes.
The first boiler pass is designed as an empty pass and is divided into a furnace and a radiation chamber. The other boiler passes accommodate the superheater, evaporator and economiser convection heating surfaces. All convection heating surfaces can be cleaned during operation with soot blowers. The superheated steam temperature is controlled by means of injection coolers between the superheater heating surfaces. Additional economiser heating surfaces at the end of the boiler, as well as, further heat exchangers for the provision of process or district heat increase the overall efficiency of the system.
