The boiler is designed as a horizontal waste heat boiler with three empty passes and utilizes the waste heat from the flue gases of a rotary kiln combustion process for various types of waste (2s 1100°C). The heating surface cleaning is carried out using a Shower Cleaning System (SCS) and pneumatic rappers. Evaporators, superheaters, and eco-bundles are integrated into the horizontal pass.
Technical data:
- Flue gas: 47500Nm³/h, 1150°C
- Steam production: 26t/h, 32bar(a), 330°C (+3.5t/h saturated steam for flue gas reheat)
Scope of services:
- Thermal design
- Design of the natural circulation system
- Basic Engineering incl. load plan and 3d model
- Detail Engineering incl. fabrication drawings for the steam drum
- Guiding drawings for critical elements (headers, buckstays, supports etc.)
- Statical calculation of the supports using FEM methods (high seismic loads)
- Pipe stress analysis for relevant internal piping
- Project coordination
