Stacks, Cooling Towers and other Special Constructions

Tasks

a) Chimney

Gathering and processing of experience to ensure undisturbed chimney operation
Establishing and assessing operating conditions (operating modes, flow conditions, thermal and chemical influences)
Establishing structural design data
Evaluation of construction methods
Notes on execution, design recommendations
Outlining of design problem solutions for extraordinary operating conditions
Recommendations for condition monitoring
Active co-operation in context with the preparation or revision of relevant national and European standards (e.g. DIN EN 13084, EN 1993-3-2, DIN 1056, DIN 4133)

b) Cooling towers

Establishing and assessing basic data of cooling technology
Presentation and assessment of various cooling processes
Analysis of operating conditions and resulting effects on building structures
Optimisation of structural cooling facilities
Establishing structural design data for large cooling towers
Development of calculation and assessment processes taking into account the required serviceability and a corresponding stability concept
Definition of material requirements/quality assurance measures
Design and execution instructions
Exerting substantial influence on the applicable construction regulations and checks and approvals by authorities

c) Special structures

Planning, design and execution of vessels and silos
Design and execution of pipings (exhaust pipes, cooling water pipes, flue gas ducts after FGD)
Basic design and dimensioning for boiler supporting structures (under consideration of permissible subsidence values)

Advice in the planning, execution, repair or upgrading of chimneys and cooling towers
Information concerning planning and execution of protective coatings for concrete surfaces
Support with damage analyses and repairs
