Pneumatic furnace damper drives may be more common, but electro-hydraulic actuators provide several advantages to the more traditional control scheme. One fossil-fired plant in Taiwan achieved more ...

It also focuses on compartmentation and the dampers used to prevent the spread of heat, fire, and smoke as they contain products of combustion. Chapter 9 of the IBC contains requirements for ...

The main objective of this project is to develop and test a phased damping device, or “gap damper”, to act alongside a base isolation system for buildings or bridges. The gap damper provides ...

The International Fire Code (IFC) requires periodic testing of life safety dampers and smoke control systems. There are some state or local variations, but the requirements are essentially the same in ...

THIS column provides information about the use of outdoor air dampers in hot and humid climates and during hot and humid seasons in temperate climates in commercial buildings. Terms used in this ...

The inlet-air section of a utility boiler is a harsh environment for the dampers that control the flow of preheated air into the combustors. Over time, the hot air dries out the lubricant in the metal ...

Coil spring force line control is an important aspect of spring design for coil-over-shock suspension type applications, such as MacPherson strut and coil-over-shock trailing arm applications, from ...
