After 1981, the ships were sold and re-equipped with what were more fuel-efficient diesel engines at the time, but the increase in engine size reduced cargo space. Several experiments have been conducted with cars powered by gas turbines, Chrysler’s largest. More recently, there has been some interest in using turbine engines for hybrid electric cars. For example, a consortium led by microturbine gas company Bladon Jets has secured investments from the Technology Strategy Board to develop an ultra-light range extender for next-generation electric vehicles. Air breathing jet engines are gas turbines optimized to produce thrust from exhaust gases or guided fans connected to gas turbines. Jet engines that produce thrust from the direct impulse of exhaust gases are often called turbojets, while engines that generate thrust with the addition of a guided fan are often called turbofans or fan jets.
All this often makes the construction of a simple gas turbine more complicated than a piston engine. For a turboprop engine, there will be a certain balance between propeller power and jet thrust that provides the most economical operation. In a turbojet engine, only enough pressure and energy is extracted from the current to drive the compressor and other components. The remaining high-pressure gases are accelerated by a nozzle to provide a jet to propel an aircraft. A combustion engine in a power plant used to switch natural gas or fuels from liquid energy to mechanical energy is known as a gas turbine.
Power companies often use gas turbines in the size range of 5-40 MW to provide incremental capacity and grid support. A significant number of UAA-based CHP systems are in use in a variety of applications, honeycomb seal including oil recovery, chemicals, paper production, food processing, and universities. T Rotates turbine blades by heating a mixture of fuel and air to extremely high temperatures to produce power.
This converted energy is used to power an electric generator that generates the electrical current used from power lines to businesses and homes. Several pollutants have been significantly reduced, including sulfur dioxide, carbon dioxide and nitrogen oxides. Open-cycle gas turbines emit waste heat into the atmosphere, which can adversely affect the environment. Combined cycle gas turbine plants do not have this problem because they reuse waste heat to generate more energy. CCGT technology is undoubtedly a popular choice for many natural gas plants.
After the organization of the petroleum exporting countries’ dramatic price increases in the mid-1970s, operations were constrained by rising fuel costs. Some modifications were made to the engine systems of these ships to allow the combustion of a lower fuel type (i.e. marine diesel). Lowering fuel costs was successful using another, untested fuel in a marine gas turbine, but maintenance costs increased with the fuel change.
