Turbine generators

Power Generation. The power generation turbines can be further divided into three categories ... 

This type of turbine is similar in all respects to the steam power-generator turbine but is considerably simpler, not having as many wheels, nor the same power plant economics to consider. For a general description, see Table 14-15. Neerken is an excellent reference to steam turbine... 

Electricity is produced by the conversion of heat energy (produced in a boiler and transmitted as steam) into mechanical work by use of a turbine, which is connected to an electrical generator (turbine generator). 

Methanol is a clean-burning liquid that can be used to power electricity-generating turbines as well as a fuel for automobiles and other vehicles. It can also be a valuable feedstock for a variety of chemicals (e.g., in the manufacture of acetic... 

Most electric power plants produce electricity from steam that is used to rotate a power-generating turbine. The heat contained in the steam after it condenses is lost to the environment. In many industrial processes steam or heat is produced during production, but the mechanical energy in the steam or heat is not utilized. 

Find the temperature at the exit of the compressor T ), the temperature at the exit of the gas generator turbine (T4), the temperature at the exit of the power turbine compressor work required per unit... 

Find the temperature at the exit of the compressor (T2), the temperature at the exit of the gas generator turbine (I4), the temperature at the exit of the power turbine (Fsa), compressor work required per unit mass, gas generator turbine work produced per unit mass, power turbine work produced per unit mass, heat supplied per unit mass, net work produced per unit mass, total power produced by the cycle, and cycle efficiency. 

For example (Table 3), one operator had a production power peak load of 14 mw. Two 15-mw power generation turbines were provided for the duty. Liquid fuel consumption would be too great for the large units, before gas was available, so smaller power generation sets were provided thU... 

Phasing allowed use of a nonused drilling power turbine later in the life of the field. Hence, only 4 x 3.3-mw units were selected for the production side of the operation. During a short period of simultaneous drilling and production, if a 3.3-mw power generation turbine went down, a water-injection pump would need to be dropped temporarily. This was accepted by the operator as a minor handicap. 

At the completion of drilling, all former power-generation turbines dedicated to drilling would be turned over to production as backup/standby or available for future increments of production/reservoir support power loads. 

Gas cooled reactors use carbon dioxide under pressure as a recirculating heat transfer medium (coolant) between the hot nuclear reactor core and water in a secondary circuit in order to raise steam and electrical power in an otherwise conventional high pressure steam generator/turbine/condenser loop. The role played by ion exchange is denoted by systems A-D in Figure 8.22. 

The power conversion vessel contains the turbomashine and three compact heat exchangers. The turbomashine consists of a generator. turbine and two compressor sections, mounted on a single shaft suspended by magnetic bearings. 

This discussion for the case study comes from Couch and Leonard (2006). The purpose of using this case study here is to show the benefits of integrating power generation turbines with the existing steam system. 

The secondary circuit comprises the steam generators, turbine, condenser, condensate pumps, deaerator, feedwater pump, feedwater heaters, bypass line, connecting pipes and control valves.
