DP - Design and Pre-Engineering Consultancy Services
One of DP CleanTech’s core competences is the design and engineering of biomass and waste-to-energy combustion systems. Our original technology is present in some of the first biomass power plants in the world which are still running well today. Pre-engineering packages are often required to provide proof of concept for the technology; or to provide a headstart on the project whilst it is awaiting certain approvals. The pre engineering phase can be conducted by DP as a standalone exercise. DP employs cutting edge CFD software to simulate the internal combustion conditions of the boiler. Our detailed knowledge of biomass and waste fuels allows each new project to be optimally designed according to the specific fuels involved and local legislative standards.
CFD (Computational Fluid Dynamics)
Biomass fuels have more complex characteristics than fossil fuels; and their different physical and chemical characteristics can lead to situations such as heavy slag buildup or unstable combustion. This results in a high amount of unburnt fuel in the ash. For complex fuels and special equipment requirements, boiler dynamics need to be very specifically designed and DP’s expert engineering team uses advanced CFD modeling to optimize the boiler design. Air flow and temperature distribution in the combustion chamber; as well as the emission concentration (NOx and SOx) are simulated in order to optimize the boiler design.
DP creates 3D plant models during the Design and Pre-Engineering phase. This is an important design tool for both engineering and our clients. From the 3D model, clients can see the equipment design as well as its positioning in the plant, and can envisage the boiler equipment and equipment relationships. The model can also provide a simulated plant tour in 3D which is an important functionality for checking equipment and piping layout and planning as well as checking for collision and conflict during integration of DP equipment and other suppliers.
