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.

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.

Portable pH Calibrator

I am just surfing the internet to find a good thing on our instrumentation device. Then I found this one of the ABB products. Portable pH Calibrator is using to simulate variable pH and also can be as pH analyzer and calibrator. It is extremely useful for grab sample pH measurement as well as bench setup and field calibration or troubleshooting of process pH analyzers.

Model TB100 Portable pH Analyzer/Calibrator

When it comes to deal with process pH instrumentation, I personally thinking that this kind of calibrator is very essential and very good to have one. Very easy to use and the result can be much better. I am not sure how much it will cost. But you will save a lot of money when you can cut your cost to purchase buffer solution to do monthly calibration.

Trial Instrumentation Field Device ECP Flow Switch Chlorine Application Failed

Again, this morning operation raised defect to us on Electro Chlorination Plant (ECP) flow switch problem. After a few days switch has been installed with minor modification on the probe; new spring changed to stainless steel and the flapper is coated with anti-oxide hoping that the lifetime can be longer than before, but the result frustrated. There is already a few times I mentioned in this blog that the unreliable flow switch urgently needs to be replaced as the ECP Cell downtime very frequently happened.

Recently, Vega and Endress Hauser tested their probes on the ultrasonic type. It took one week to complete in January. The tuning of the parameters has been done for a few times to get a good result but at the last stage it failed. The reason it failed is the flow rate is not stable due to two medium mixture, water and air bubbles. In this case, air bubbles will absorb the signal from the ultrasonic then cause the reading fluctuating. At the end, they would like to trial another type of measurement either magnetic or different pressure DP type. But I am still waiting for them to their recommendation which has been promised in February.

I still remember that the current Flotech flow switch that we are using already more than two years. But recently in these 3 to 4 months, the flow switch flapper and the spring brittles and easily broken. Actually this is not the first time we change to a new brand on ECP flow switch. If I am not mistaken, it is already third or fourth times since 2004. So far most of our instrumentation field devices when comes to a new solution doesn’t give us much trouble. Aaarrrgghh… meaning that I have to find out other new brand or new type of flow switch to cut this problem from happens and happens again.

At this moment, I have to contact various manufacturers to recommend the suitable flow switch on the chlorine application which urgently required including ABB, UE and Kelco. Since the stocks balances at the store for the old type (Flotech) are very critical low therefore we need to reorder for temporary used.

New Pressure Gauge to be Fitted at The Condenser Inlet Pipe

The reason to fit the pressure gauge is to investigate the Cooling Water Pump problem and condenser performance. On each inlet and outlet leg there are stubs fitted with isolating valves and blank flange. Isolate, remove flange and drill and thread to suit pressure gauges. (Note one inlet leg has no isolating valve) Suggest gauges have to be as fitted on CW discharges i.e. SS 150MM dia, range 0 to 6 bar. See attached Photos.


On the outlet sides propose to fit gauges at lower level to make reading easier by piping impulse line down to suitable mounting location.

Unit No.1 High Pressure Heater No.6, 7 and 8 Emergency Control Valve Not Fully Shut

HP HTR 8 level transmitter showing very low reading. Check at local gauge glass found actual level low. Check at the emergency control valve found, High Pressure Heater No.7 and No.8 valve position not fully shut and causing the HP HTR level drain to the flash box. DCS command to the control valve already fully shut. Suspect not enough air pressure to close the control valve (air to close).

After doing some checking, not enough air pressure to close the control valve from the volume booster. The function of volume booster is to boost big volume air to the valve diaphragm either fast closing or fast opening. Servicing done for all volume booster HP Heater and reading back to normal operation.

Checking at the store found that the stock level for this volume booster is also low and need to raise new purchase request. I enclose here the photo and the specification for you to review.
