Practical Distributed Control Systems (DCS) for Engineers and TechniciansLiving Online
This workshop will cover the practical applications of the modern Distributed Control System (DCS). Whilst all control systems are distributed to a certain extent today and there is a definite merging of the concepts of a DCS, Programmable Logic Controller (PLC) and SCADA and despite the rapid growth in the use of PLC’s and SCADA systems, some of the advantages of a DCS can still be said to be Integrity and Engineering time.
Abnormal Situation Management and Intelligent Alarm Management is a very important DCS issue that provides significant advantages over PLC and SCADA systems.
Few DCSs do justice to the process in terms of controlling for superior performance – most of them merely do the basics and leave the rest to the operators. Operators tend to operate within their comfort zone; they don’t drive the process “like Vettel drives his Renault”. If more than one adverse condition developed at the same time and the system is too basic to act protectively, the operator would probably not be able to react adequately and risk a major deviation.
Not only is the process control functionality normally underdeveloped but on-line process and control system performance evaluation is rarely seen and alarm management is often badly done. Operators consequently have little feedback on their own performance and exceptional adverse conditions are often not handled as well as they should be. This workshop gives suggestions on dealing with these issues.
The losses in process performance due to the inadequately developed control functionality and the operator’s utilisation of the system are invisible in the conventional plant and process performance evaluation and reporting system; that is why it is so hard to make the case for eliminating these losses. Accounting for the invisible losses due to inferior control is not a simple matter, technically and managerially; so it is rarely attempted. A few suggestions are given in dealing with this.
Why are DCS generally so underutilised? Often because the vendor minimises the applications software development costs to be sure of winning the job, or because he does not know enough about the process or if it is a green-field situation, enough could not be known at commissioning time but no allowance was made to add the missing functionality during the ramp-up phase. Often the client does not have the technical skills in-house to realise the desired functionality is missing or to adequately specify the desired functionality.
This workshop examines all these issues and gives suggestions in dealing with them and whilst not being by any means exhaustive provides an excellent starting point for you in working with a DCS.

I have attached this report where we find out the actual reason steam turbine Deaerating Condenser Performance degradation which was written on June 06, 2012.That time I was in Haripur Power Limited (HPL) ,A 360 MW CCPP of Pendekar Energy Bangladesh Ltd.
The report outcome showed that the Steam turbine load could be reached to its maximum capacity after those valve maintenance works on the next Steam Turbine Major inspection on 2013.We hope we can increase our steam turbine load to 5-7 MW/D on that time.
The operational guys were indicating Circulating water pumps (CWP A&B) were not performing to its design capacity & Ejectors/vacuum pumps are not performing well.So,Mechanical Maintenance Team (MMT) team find this successful outcome after several study.
Condenser vacuum condition has improved a lot after maintenance of the valves on last Major Inspection on 2013.
It is a sample report where we can realize that identifying actual reason for an equipment performance is not only a job of operational people but also a responsibility of the maintenance guys.

A boiler is a device that produces steam or hot water for heating or industrial purposes. Boilers are used in a variety of applications, including:
Heating homes and businesses
Generating electricity
Cooking food
Sterilizing medical equipment
Processing chemicals
There are many different types of boilers, each with its own advantages and disadvantages. The most common type of boiler is a water-tube boiler, which uses a series of tubes to heat water. Other types of boilers include fire-tube boilers, which use a series of tubes to heat fire, and steam generators, which use a series of tubes to heat water and produce steam.
Boilers can be powered by a variety of fuels, including natural gas, oil, coal, and wood. The type of fuel used will affect the efficiency of the boiler and the cost of operation.
Boilers require regular maintenance to ensure that they operate safely and efficiently. This maintenance typically includes cleaning the boiler, inspecting the pipes and valves, and replacing worn parts.
Boilers are a complex piece of equipment, and it is important to have them installed and maintained by a qualified professional.
Here are some of the benefits of using a boiler:
Boilers can provide a reliable and efficient source of heat for homes and businesses.
Boilers can be used to generate electricity, which can help to reduce reliance on fossil fuels.
Boilers can be used to cook food, sterilize medical equipment, and process chemicals.
Here are some of the drawbacks of using a boiler:
Boilers can be expensive to install and maintain.
Boilers can be a fire hazard if not properly maintained.
Boilers can produce emissions that contribute to air pollution.
Overall, boilers can be a valuable asset for homes and businesses that need a reliable source of heat or hot water. However, it is important to weigh the benefits and drawbacks before deciding whether or not to install a boiler.

3. WHAT IS BOILER?
A boiler or steam generator is a device used to create steam by applying heat
energy to water.
A boiler or steam generator is used wherever a source of steam is required.
The form and size depends on the application.
A boiler incorporates a firebox or furnace in order to burn the fuel and
generate heat.

1. Fire Tube Boiler
2. Water Tube Boiler

MAIN PARTS OF BOILER
5. BOILER STEAM DRUM
A steam drum is a standard
feature of a water-tube boiler.
It is a reservoir of water/steam at
the top end of the water tubes.
The drum stores the steam
generated in the water tubes and
acts as a phase-separator for the
steam/water mixture.
6. FURNACE
A boiler incorporates a firebox or furnace in order to burn the fuel and
generate heat.
Temperature in furnace control by air fuel ratio.
7. SUPER HEATER
The Super heater has an
elaborate set up of tubing
where the steam vapor picks
up more energy from hot
flue gases outside the tubing
and its temperature in now
super heated above the
saturation temperature.
The super heated steam is
then piped through the main
steam line to the high
pressure turbine.
8. AIR PREHEATER AND ECONOMIZER
An air
preheater heats
the air sent into
the combustion
chamber to
improve the
efficiency of the
combustion
process.
An Economizer
use the heat
from the
exhaust gases
to heat the feed
water.
9. The Condenser is a tube in which
cooling water is circulated
through the tubes.
The exhaust steam from the low
pressure turbine enters the shell
where it cooled and converted to
water by flowing over the tubes.
The condenser generally uses
either circulating cooling water
from a cooling tower to reject
waste heat to the atmosphere, or
once through water from a river ,
lake or ocean.
CONDENSER
10. DEAERATOR
A steam generating boiler
requires that the boiler
feed water should be
devoid of air and other
dissolved gases,
particularly corrosive
ones, in order to avoid
corrosion of the metal.
Here, steam is used to
maintain the tank water
temperature at around
105°C, which removes air
from the water.
11. Boiler blowdown is water intentionally wasted from a boiler to avoid
concentration of impurities during continuing evaporation of steam.
The water is blown out of the boiler with some force by steam pressure within
the boiler.
A steam boiler evaporates steam from liquid water; and requires frequent
replenishment of boiler feed water for the continuous production of steam
required by most boiler applications.
BLOW DOWN TANK
12. DESULFURIZATION
Flue-gas desulfurization (FGD) is a set of
technologies used to remove sulfur
dioxide (SO2) from exhaust flue gases of
fossil-fuel power plants, and from the
emissions of other sulfur oxide emitting
processes.
13. BOILER CONTROL
Boilers are the primary source of steam and hot water generation in industrial
processing plants where steam demands vary very frequently according to the
requirements.
Hence, a well designed boiler must be capable of giving immediate response to
these load demand variations.
While doing so it must also maintain its efficiency and safety features.
In order to achieve this, various techniques of boiler control are available, like
DDC(DIRECT DIGITAL CONTROL) or DCS(DISTRIBUTED CONTROL
SYSTEM)
Here we use DISTRIBUTED CONTROL SYSTEM for Boiler Control.
