5 Environmental Effects and Tradeoffs of Biofuels

5. Environmental Effects and Tradeoffs of Biofuels. Petroleum extraction, transport, refining, and combustion have many known negative environmental effects, including disruption of sensitive ecological habitats and high greenhouse-gas (GHG) emissions.Biofuels, too, have their environmental costs (NRC, 2003, 2010a), but displacing petroleum-based fuels with biofuels can reduce the nations

Gas turbine - Wikipedia

A gas turbine, also called a combustion turbine, is a type of continuous and internal combustion engine.The main elements common to all gas turbine engines are: an upstream rotating gas compressor; a combustor; a downstream turbine on the same shaft as the compressor.; A fourth component is often used to increase efficiency (on turboprops and turbofans), to convert power into mechanical or

Injector - Wikipedia

An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts, excepting a valve to control inlet flow. A steam injector is a typical application of the principle used to deliver cold water

Boiler Feed Water Pump Working Principle and Operation

Jul 18, 2018 · Today we will discuss about (BFWP) boiler feed water pump working principle and operation of a boiler feed water pump. The boiler feed pump function is to supply pressurized feed water to the boilers maintain the water inventory at various operating loads. Boiler feed water pumps are commonly centrifugal pumps.To ensure a high enough head and pressure, Boiler feed Pumps have

Boiler explosion - Wikipedia

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.

Throttle - Wikipedia

A throttle is the mechanism by which fluid flow is managed by constriction or obstruction.. An engine's power can be increased or decreased by the restriction of inlet gases (by the use of a throttle), but usually decreased. The term throttle has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal.

Exhaust Gas Boilers And Economisers for Marine Machinery

The consequences of starting a circulating pump with the exhaust gas boiler tubes at elevated temperatures could be disastrous. On vessels with an exhaust economiser by pass valve, water temperature is a critical factor in preventing condensation and acid formation on the gas side.

Boiler Drum Level Control Systems | Instrumentation Tools

Drum Level Control Systems are used extensively throughout the process industries and the Utilities to control the level of boiling water contained in boiler drums on process plant and help provide a constant supply of steam.. If the level is too high, flooding of steam purification equipment can occur. If the level is too low, reduction in efficiency of the treatment and recirculation function.
