In this assignment I will research one part of a gas turbine engine, I have chosen to describe the combustion chamber.
A combustion chamber is a specific part of an engine where fuel is burned. The combustion engine changes heat energy into kinetic energy. There are two types of combustion engines, one which is internal and the other is external.
In an internal combustion engine, the fuel inside it is burned in the air at the top of its pistons. Most internal combustion engines are mainly used in small vehicles. In the 19th century external combustion engines were commonly used to power large steamships and trains. The combustion chamber of an internal combustion engine is limited in part. When the fuel is burnt in the combustion chamber, hot gasses can straight away push the piston down. Due to the pressure of the gas being high it quickly increases to follow the piston and to continue pushing on it. As the gas pressure goes low, the gas has then pushed the piston to its bottom place. The heat in an internal combustion chamber is made inside the engine, because it can quickly perform on the engine pistons. This then lets the internal combustion engine to be smaller and lighter than the external combustion. Due to this internal combustion engines are commonly used for mobile applications with low power. In an Internal combustion engine the increase of high temperature and pressure gases made by combustion applies straight force of the engine. Like the pistons, turbine blades or a nozzle. This force changes the component over a distance, which makes mechanical energy. ‘Internal combustion’ refers to an engine which the combustion is alternating.
In the internal combustion engine it is an engine where combustion is not the same,...

...ed through the internal mechanism.
In an internal combustion engine the actual performance of the engine is 20% and the loss by heat is 80%. The age of diesel or petrol engine is 900.000.km. There are plenty of fuel however will finish within 15 years. An external combustion engine motor changes the chemical energy that is made inside the explosion chamber, into mechanical energy. The pressure made by the explosion is directly transmitted to the piston. The heat generated by the explosion is released straight through the exhaust pipe. If this doesn’t reach the cylinder zone then this is not spread in the rest of the engine. The temperature in the engine should be around 50 degrees Celsius. But the external blasting chamber is cooled off on its own. The internal combustion engines leave solids in the cylinder. This increases the wear of the engine due to friction.

    For the first phenomena, he noted how all combustions involved the formation of fire or light. With that in mind, Lavoisier also observed that this combustion occurs only through dephlogisticated air / pure air. Other airs (e.g. carbon dioxide) act as a fire extinguisher similar to that of water. Another combustion phenomenon he outlined was how the weight of the burnt material directly relates to the amount of air used in the reaction. Moreover, he also described how certain substances turn into acids after it has been burn...

    This requires the engine to have a state-of-the-art coolant system. Big tunnels through the perimeter of the engine allows coolant to flow all around the motor at all times and keep the engine cool. The radiator is also much thicker from the factory, and is angled at 45 degrees in the engine bay to maximize air flow. The number one reason why these engines stop functioning is due to a problem with the coolant system.

    4. Exhaust: After the Air/Fuel mix has been burnt, the remaining chemicals in the cylinder (water and CO2 for the most part) must be removed so that fresh air can be brought in. As the piston goes back up after combustion, the exhaust valve opens allowing the exhaust gasses to be released. Ideally an engine takes in air (oxygen and nitrogen) and fuel (hydrocarbons) and produces CO2, H2O, and the N2 just passes through.

    Combustion is a rapid, continuous reaction that usually takes place in the gas phase. Wood is an organic compound primarily comprised of cellulose. For wood, the phase change from a solid to gas is almost instantaneous as combustion occurs (Coleman, et al. 95). Ignition occurs when an outside source is no longer needed to sustain combustion (Coleman, et al. 87).

    One type of engine is a called a fuel cell. A fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes sandwiched around and electrolyte. Oxygen passes over one electrode and hydrogen over the other, generating electricity, water and heat. Hydrogen fuel is used to make all this work. Fuel cell emissions are nothing but water vapor.

    For over a century people have relied on automobiles, planes and trains as means of transportation, industry and agriculture, it has become such a successful necessity in the modern world that it has become a need for people to use them to get by. Now sure the three basic means of transportation are entirely different in the way the function and their use. All of these means of transportation would not be possible without this invention transportation could not be possible, The Internal Combustion Engine. You might be wondering what is exactly is an Internal Combustion Engine? It’s actually a simple concept but the way it’s performed can becoming very complex. The function of is to create a pulling force through a controlled explosion of compressed air and fuel inside a combustion chamber which then pulls a crank. Depending on what type of platform the engine is on will determine what the crank turns, for an example in a car the crank then turns either a front or rear axle which that axle transversely turns a wheel. In order for this engine to function in needs three elements - air, fuel and spark and without one of these elements the engine will not function, so it takes precise timing and careful planning by the Engineers to make the engine work as required.

    The invention of internal combustion engines in the early 19th century has led to the discovery of utilisation of cheap energy that is petroleum and this enabled the world to develop and progress into the modern world today. Humans were able to accomplish more work done with little manual labour, using internal combustion engines powered by fossil fuels. Internal combustion engine are mechanical power devices that convert heat energy to mechanical energy with the combustion process taking place in a system boundary (Rolle, 2005). Among the internal combustion engine invented in the 19th century were the Otto engine, Diesel engine and gas turbine engine. Gas turbine engine is one of the popular engines used today due to its high torque per weight ratio relative to other types of internal combustion engines. As explained by Cengel and Boles (2011), the gas turbine engine works on a 6 stages process, namely air intake, compression, fuel injection, combustion, expansion and exhaust (refer to Figure 1 in Appendix 1).

    This along with the lighter construction of a two-stroke makes it the preferred motor used in small vehicles and tools (Two Stroke Engine). A two-stroke engine is operated by first drawing the mixture of fuel and air into the chamber by the vacuum caused by the upward stroke of the piston. During the downward piston stroke, the poppet valve is forced closed due to the increased pressure within the chamber. The mixture is compressed in the chamber throughout the stroke. As the stroke ends, the intake port is exposed allowing the mixture to escape into the main cylinder, expelling the exhaust gasses in the process and some of the fuel mixture as well. Momentum then causes the piston to rise, compressing the mixture as another stroke is beginning. Once the stroke reaches its peak, the spark plug will ignite the mixture causing the fuel to expand driving the piston down thus completing the cycle while additionally initiating a new

  • Steam Turbine Essay

    805 Words  | 2 Pages

    A steam turbine's two main parts are the cylinder and the rotor. As the steam passes through the fixed blades or nozzles it expands and its velocity increases. The high-velocity jet of steam strikes the first set of moving blades. The kinetic energy of the steam changes into mechanical energy, causing the shaft to rotate. The steam then enters the next set of fixed blades and strikes the next row of moving blades. As the steam flows through the turbine, its pressure and temperature decreases, while its volume increases. The decrease in pressure and temperature occurs as the steam transmits energy to the shaft and performs work. After passing through the last turbine stage, the steam exhausts into the condenser or process steam system. The kinetic energy of the steam changes into mechanical erringly through the impact (impulse) or reaction of the steam against the blades.
