A seven-flue chimney in a four-storey Georgian house in London, showing alternative methods of sweeping. A flue is a duct, pipe, or opening in a chimney for conveying exhaust gases from a fireplace, furnace, water heater, boiler, or generator to the outdoors.
Schematic diagram of an industrial process furnace. Fuel flows into the burner and is burnt with air provided from an air blower. There can be more than one burner in a particular furnace which can be arranged in cells which heat a particular set of tubes. Burners can also be floor mounted, wall mounted or roof mounted depending on design.
External access point for fire sprinkler and dry standpipe at a building in San Francisco, US Antique wet standpipe preserved at Edison and Ford Winter Estates. A standpipe or riser is a type of rigid water piping which is built into multi-story buildings in a vertical position, or into bridges in a horizontal position, to which fire hoses can be connected, allowing manual application of water ...
A diverterless supersonic inlet (DSI) consists of a "bump" and a forward-swept inlet cowl, which work together to divert boundary layer airflow away from the aircraft's engine while compressing the air to slow it down from supersonic speed. The DSI can be used to replace conventional methods of controlling supersonic and boundary layer airflow.
In a water boiler, draft is the difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage. [1] Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow.
Q = discharge of inlet (ft 3 /s) W = width of the chute or inlet (ft) H = depth of flow over the crest (or floor) of the inlet (ft) H e = specific energy head in reference to the crest of the inlet, or the head over the crest of the inlet (ft) v a = mean velocity of approach at which the depth H is measured (ft/s) g = 32.16 ft/s 2
Breeching is a horizontal strap that goes around the horse's haunches allowing the horse to slow a vehicle or hold it back when going downhill. It is usually hooked to the breeching dee on the shafts by breeching straps. Used for a single horse, a pair, or in a larger team, only for the wheelers (the animal or pair closest to the vehicle). The ...
An illustration exists of a unitless E – Y diagram and how Energy and depth of flow change throughout a Parshall Flume. The two blue lines represent the q values, q 1 for the flow before the constriction, and q 2 representing the value at the constriction (q = Q/b = ft 2 /s, or flow over width in a rectangular channel).
