Geothermal Power Plan

Geothermal energy is one of the renewable energy sources because the amount is very large and will not run out. Indonesia is lucky to have many geothermal sources because Indonesia is traversed by a ring of fire where there are many volcanoes along the ring of fire and of course it can be a benchmark for how many geothermal sources there are. Geothermal sources that will be used to become geothermal power plan, what is geothermal power plan?

Geothermal Power Plan

Geothermal power plant, this plant utilizes geothermal energy as a source of energy. The working concept is almost the same as a boiler, only the heat source comes from geothermal, not from burning coal.

The working concept is like a kettle, it's just that the kettle referred to here is the layer of soil below the earth's surface. Geothermal uses geothermal resources, this heat comes from melted rock in the earth or called magma, this magma is usually in an inactive volcanic area. Magma lies deep below the earth's surface. For years rainwater falls and enters the earth through gaps or cracks in the earth's surface and gathers in reservoirs above the ground, this magma will heat the water to temperatures above 500 degrees Fahrenheit or about 260 degrees Celsius.

To get the fluid in this case the steam from the heating of the water in this reservoir, wells are drilled to a depth of 1000 meters to 3000 meters from the earth's surface. These wells are called production wells, these production wells will bring geothermal liquid to the surface because naturally the high pressure in the reservoir due to heating, this liquid will automatically be pushed out. After coming out to the surface, this liquid will enter the processing facility. What are the facilities for processing pressurized liquids from deep within the earth?

1. Well Head

Well head serves to regulate and monitor the flow of hot liquids from the earth because the well head has a valve and several instruments such as pressure and temperature monitoring.

2. Separator

After leaving the well head, the hot liquid will enter the separator. This separator serves to separate hot steam from hot water, because the only thing that will enter the system is my hot steam. Meanwhile, this hot water will be accommodated in the pool for further pumping back into the earth or reservoir to be reheated. The separated hot water is called brine.

3. Piping

All of these processes of course require a reliable piping or piping system, to drain this hot steam, the pipes used must be insulated so that the temperature inside the pipe is properly maintained so that the hot steam can work optimally, in addition to protecting living things around such as humans. and animals to avoid direct contact with hot pipes. This pipe usually crosses a very long line of more than 3 kilometers to get to the generating facility, because this pipe network is very hot and will expand when filled with hot steam, therefore every few hundred meters is installed what is called an expansion circle where the pipe is installed. slightly twisted.

4. Scrubber

Sebelum masuk ke fasilitas pembangkit uap panas ini terlebih dahulu masuk ke proses pemurnian terakhir untuk membuang semua kotoran dalam fasilitas scrubber.

5. Turbin & Generator

Just like a boiler, hot steam that has been purified will enter the turbine to drive the generator turbine. This turbine is connected to the shaft to an electric motor or we call a generator to further generate electricity.

6. Cooling Tower

Cooling tower serves to cool the residual steam coming out of the turbine

Thus a brief discussion of geothermal power plants, may be useful.

Text And Mtext In Autocad

The Difference Between "Text" And "Mtext" In Autocad And How To Convert It In operating AutoCAD we often encounter or use writing with the aim of providing information, showing something, etc. so that our drawings are easier to understand. To write in AutoCAD, we know that there are two options, the first is "TEXT" and the second is "MTEXT". So what are the differences between the two? TEXT For "text" itself we can call it single text or single writing. So if we use "text" we can only write one sentence in one piece of text. The disadvantage of this "text" is that it doesn't have any editing menu, we can't adjust or adjust our needs in this paper, instead we must first enter the properties menu. This means that from this "text" we can only edit the written content. To use this "text" we can use the command type "DT" then press enter. MTEXT As for "mtext" itself is an ab

Genset Heating Procedure

Genset Heating Standard Procedure Genset is one of the equipment that functions to convert mechanical energy or rotation of the rotor into electrical energy. The generator has two main parts, namely the motor generator and the generator engine (usually a diesel engine), both of which are connected by a shaft. The generator itself has two main parts, namely the rotor and stator. The stator is the stationary part, while the rotor is the rotating part. This generator works when the genset control panel receives input if the power source from PLN dies, then the PLC or ATS (automatic transfer switch) will give an order to the genset control panel to turn on the generator, this is done automatically. What if the generator has to be turned on manually, for example when heating the generator? Genset as one of the supporting utility facilities of a building must of course be maintained regularly, one of which is heating the generator as one of the genset maintenance procedures. To warm up the g
