Rota - Stacks, Chimneys and Ducting for Power Plants

Rota specializes in the design, consultancy, manufacturing and erection of industrial systems. Rota provides complete engineering solutions for power and process industries. One of Rota's specialities is stacks, chimneys and ducting for power plants. Its full range of capabilities is as follows:

• Power plant equipment, including stacks, chimneys, ducting, silencers, diverters, dampers and expansion joints
• Cogeneration with gas engines
• Vessels / storage tanks
• Heat exchangers

Stacks / chimneys for power plants

Rota designs, manufactures and erects cold (inner) insulated or non-insulated by-pass and main stacks at high temperature in the service of cogeneration and combined cycle power plants. The compact insulation design compensates the material extension and elongation due to the high temperature.

Rota also produces all types of process stacks. Various kinds of carbon and stainless steel and alloy steels are the materials most commonly used in these kinds of stacks.

Rota's experienced personnel and international engineering practices combined with a quality assurance system ensure high-quality and reliable products and services.

Internally insulated ductwork for power plants

Rota power plant stacks and ductwork are internally insulated with ceramic fibre or rock wool material that is covered by a stainless-steel tile system. The internal insulation maximizes heat retention and minimizes external thermal growth, eliminating frame distortions and stresses.

Dampers and expansion joints

Many types of dampers and expansion joints are in the Rota production line and have been installed all over the world for years. Turnkey solutions on design, manufacture and erection of tight shut-off louver and fully sealed multi-louver dampers provide gas flow control and/or isolation of power and industrial systems and equipment.
