What are the sources of heat that are used to generate...

Key Concepts

Geothermal Energy

This source harnesses the naturally occurring heat from the Earth's interior. Water heated by geothermal processes can be directly converted to steam, providing an environmentally friendly method for energy production.

Solar Thermal Energy

Solar thermal systems concentrate sunlight to produce significant heat. This concentrated thermal energy heats water to generate steam, which can be used in power generation or other industrial applications.

Combustion Processes

This refers to the process of burning fuels, such as fossil fuels like coal, oil, or natural gas, to release thermal energy. The heat produced from combustion is transferred to water in a boiler, generating steam through the energy conversion from chemical to thermal energy.

Nuclear Fission

Nuclear reactors use the process of fission, where heavy atomic nuclei split to release a substantial amount of heat. This heat is then used to convert water into steam, which can drive turbines for electricity generation.

00:01 We're asked in a combined gas steam cycle, what is the energy source for the steam? well, the energy source, i mean, that's a simple answer.

00:14 And i'm not sure how much there is to expand on it.

00:17 But the energy source for the steam is the waste energy and the exhaust of the combustion process.

00:22 So basically, what we're doing in the combustion process, we have a cycle that looks something like this in the t.

00:29 Diagram.

00:32 And so when we're normally we'd be dumping heat out of here.

00:36 Right.

00:38 Putting, you know, this would be the combustion and we're getting creating putting heat in from the combustion process and then we're extracting some work and we're dumping some and then we're pressing again and you know.

00:50 So the problem the thing is is that we're dumping this heat out but in a gas, in a gas turbine, this is at a very high temperature.

01:01 So it's the exhaust basically coming out of the, you know, coming out of the combustion that went through the turbine.

01:07 And it's going to be at a really high temperature because we have a very high temperature turbine here.

01:13 So it's basically like, you know, the exhaust coming out of like that end, right? it is very hot.

01:20 And instead of just dumping that into the atmosphere, we can then take some of that exhaust or use that exhaust and then use it basically as a boiler...
