Introduction to Coal Fired Power Plant

From a coal stockyard, coal will send to mill bowl through the coal bunker before it goes to boiler to heat water to the superheated steam. The superheated steam at the correct temperature and pressure flows into a turbine which spins a generator to produce the electricity before introducing to the transmission line. The bled steam is cooled, condensed back into water and it will return to the boiler to start the same process over. The following image illustrate the general process how coal fired power plant generate or produce the electricity.

Arizona to Get Large Solar Power Plant

Currently it is in planning stage for Spanish company to build the largest solar power plant in Arizona. The operational of the Arizona solar power plant will produce 280 Megawatt solar energy and the plant will sell around $4 billion in clean electricity over 30 years.

Arizona Solar Power Plant in Project Planning Stage

The solar plant located is 70 miles of Phoenix, near Gila Bend Arizona scheduled to be operate in 2011. If the solar plant energy is approved, it will be the largest solar power plant in the world and the construction could be begin as early as next year.

My Handphone - Nokia 2100

Currently I use this handphone on daily basis. It is already one year I used this Nokia 2100. Even this handphone is cheap and very simple compared which existing in the market with various function and latest technology, my Nokia 2100 gave me no problem at all since I bought it last year.

Nokia 2100 Specification
- Monochrome Graphic
- Monophonic
- Phonebook 100
- Standard Li-on 720Ah Battery

I am sure most of my colleagues already change their own hanphone with the sophisticated and the latest technology. Camera, GPRS, 3G, polyphonic, great audio and etc. Me? I might thinking of it but at the same time I will not spend unwisely just to get a new one. Haha... In the future post, I will consider to write about the latest technology handphone which can be reviewed by my readers. Enjoy!

Beautiful Night Scene at Coal Fired Power Plant

I found this photo in flickr. This coal fired power plant night scene is very beautiful.

Three chimneys or stacks photo shot with good angle and the color is beautiful. The reflections are great. Do you know where it is located? Or it just an illustration. Never mind, anyway it is a nice pic!

Digital Temperature Transmitter

At first in my previous post I think this instrumentation device is called temperature or RTD's converter. But when I surfed the internet about this equipment, it's name 'Digital Temperature Transmitter'. Currently used at Turbine Generator area and some areas in power plant.

Digital Temperature Transmitter

Application
- Machinery, Plant Construction
- Process Industry

Special Features
- Universal via Window PC
- Isolation voltage 1500VAC between sensor and current loop
- Signalling configurable for sensor burnout and sensor short circuiting

Designation of terminal connectors

Connection of Programming Unit PU348


Accessories

On the accessories, I found that there is one configuration software which need to be ordered separetely by enduser. My specification required for this instrumentation device is;

Pt100 3/L/f
DC 9....36V
4 to 20 mA
0.... 160 degree C

How to order? If this device need to be configured first, we need also the software configurator.

Hydroponic pH Meter Application

I stumbled upon this hydroponic pH meter which is widely used in agriculture industry. Just for sharing among my readers this instrumentation test equipment is very important especially in water content analysis.

Hydroponic Deep Water System

Hydroponic relatively low maintenance and highly very efficient.

Hydroponic pH Meter

Monitoring the level of pH is quite essential. When the pH is not at the proper level the plant will lose it's ability to absorb some of the essential elements required for healthy growth. Most of the plants will growth in acid environment 6.0 to 6.5 pH event the pH level is vary from plant to plant.

Heat Exchanger

Heat Exchanger is a package equipment built for efficient heat transfer from one medium to another medium. Car radiator is one common example of heat exchanger which hot engine-cooling fluid transfer heat into air flowing through the radiator.

Heat Exchanger is widely used in space heating, refrigeration, air conditioning, power plant, chemical plant, petroleum refinery and natural gas processing.


This is the common view of heat exchanger in my power plant. Only the color is different. Just want to match with common color in this weblog. Haha...

Nature of Fluid Flow Through The Plate Heat Exchanger

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. The idea behind this concept of a heat exchanger is the use of pipes or other containment vessels to heat or cool one fluid by transferring heat between it and another fluid.
