Turbocharged engines[change | edit source] A turbocharger is a small fan pump that spins around a shaft. The pump is driven by the pressure of the exhaust gas. A turbocharger consists of a turbine and a compressor. They are both mounted on the same shaft. The turbine is a heat engine.
In the coal gasification process the air and stream are added to the raw coals then heat it to hundred degrees Fahrenheit. The carbon in the coal then react with the oxygen and the water then produces other gases such as carbon dioxide, carbon monoxide, hydrogen and methane. The carbon dioxide from the process is waste and can go to the atmosphere. The other gases can be burned or sent to the next process. Then the second process is after we get the processed and filtered coal, gas or water or carbon dioxide can be added to balance the amount of carbon monoxide and hydrogen.
Important thermodynamic information, such as the enthalpy of combustion, could be obtained by measuring the temperature change. The bomb is immersed in a quantity of water and surrounded by an adiabatic shield that serves as the heat insulator. In this experiment, a commercial bomb calorimeter (Parr) is used to determine the heat of combustion of an organic compound. The sample is held in a cup that is placed near the ignition wire that is used to start the combustion reaction as shown in Figure 1. Figure 1: Schematic of a constant volume bomb calorimeter.
Also, we watched as the water boiled and made observations as the temperature as it started to boil. This is done on a Virtual Lab. Materials: (Virtual Lab) * Water * Ice * Water-heating device or heater * Metals(Aluminum, Steel, Copper, Lead) * Electrical Balance Procedures: SPECIFIC HEAT OF METALS: * Weigh the mass of the metal samples * Fill up the calorimeter to 100mL. It should be at 25C * Heat up the Aluminum Sample to 200C * Drop the Aluminum Sample in the water and record the temperature changes. * Repeat with the rest of the samples.
This makes the temperature of the fluid in the system to change, and so does the temperature of the dividing walls between the two fluids. Examples of heat exchangers are; intercoolers, preheaters, oil coolers of heat engine, condensers, and evaporators in refrigeration units (Harriman 289). Various types of heat exchangers have been developed to meet the widely varying applications and are classified according to; nature of heat exchange process, physical state of fluid, constructional and design specs and relative direction of fluid flow. According to the nature of the heat exchange process, heat exchangers are classified as; direct and indirect contact heat exchangers. Plate and shell heat exchanger, combines both the plate heat exchangers and the shell exchangers for maximum efficiency.
