Engineering and expert office for steam boiler plants and refractory construction

We get to the heart of the matter – Competence and know-how at your service

Welcome to TROST Energy Consult — your engineering and expert office for steam boiler plants, refractory lining, circulating fluidized bed firing, and much more. Situated in Flensburg, Germany’s northernmost port, we have many years of experience in our specialized fields and a great team that builds on this solid foundation. Together, we are always on the look out for innovation and practical solutions - connecting well-founded and comprehensive expertise with a clear view of the future.

Our primary focus as engineers is on consulting. Here, we concentrate on furnace and power plants as well as thermal processing plants, especially within the fields of energy and the environment, but we also deal with the chemical and the metal industry. You will benefit from our expertise in circulating fluidized bed combustion, pulverized coal firing, and grate firing. We are familiar with all types of rotary kilns and boilers, as well as diverse plants, models, and fuels.

We are familiar with all requirements connected with the conditions on site at the plant and with design, installation and commissioning - here we are happy to lend you our keen eye for inspection and damage analysis. We prepare expert opinions and provide quality monitoring during construction. In this way we create security and optimize processes. Efficient life cycle management is just as much a part of our tasks as the development of remediation concepts and the planning and coordination of maintenance measures.

Experts for refractory 

Refractory construction or, to be more precise, refractory lining in plants is one of our areas of expertise. It protects the compounds of a plant from chemical dangers, high temperatures and the mechanical effects on boilers and rotary kilns during circulating fluidized bed combustion and grate firing. We are proven in theory and practice and bring the requirements and problems to the point. We are familiar with different lining systems and materials in refractory construction.

Experts for steam boiler plants

A further special field are steam boiler plants. More precisely, the optimisation of operation and maintenance of steam generators, as well as the planning and monitoring of plant revisions for fluidised bed and grate firing systems, firing systems for pulverised, gas and liquid fuels of fossil or biogenic energy sources as well as waste fractions and sewage sludge. We withstand the pressure to solve operational challenges.
