A roof turbine ventilator, colloquially known as a 'Whirly Bird' is an application of wind driven ventilation. Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems.
Wind-powered roof turbine ventilator. Mechanical attic ventilation fans may be powered in a variety of different ways. Most attic ventilators fitted to homes are powered off mains electricity. A trend towards solar-powered attic ventilators is observable in the interest of conserving electricity and lowering monthly utility bills.
Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.
MPI Resolution installing the foundation of an offshore wind turbine. MPI Resolution (formerly TIV Mayflower Resolution) is a wind turbine installation vessel deployed to install turbines at offshore wind farms. It was the first self-elevating Turbine Installation Vessel in the world. [1]
Moreover, the extra inlet-cooling kilowatt uses less fuel than the new turbine kilowatt due to the lower heat-rate (higher efficiency) of the chilled turbine. Other benefits may include the incrementation of steam mass flow in a combined cycle, the reduction of turbine emissions (SOx, NO x, CO 2), [21] and increase in power-to-installed volume ...
Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
Construction has been ongoing on the Vineyard Wind 1 project through the New Bedford Marine Commerce Terminal with vessels transporting the turbines to the wind farm site 15 miles south of Martha ...
