2. It is a first super thermal power plant of RAJASTHAN
state.
It is located at SURATGARH in GANGANAGAR
district.
It has 6 units right now in the working.
 Here each and every unit has 250MW capacity.
It’s total capacity is 1500MW.
There are two another units are also on construction
which has capacity of 660MW each.
This power station continue supply from 1999 .

4. WHAT IS THE BOILER:-
Boiler is a closed vessel in which the water under pressure is transferred into
steam by the application of heat.
FUNCTION :-
The function of boiler is to transfer the heat to the water in the efficient
manner.
WORKING:-
The chemical energy convert into the heat energy by the combustion process
which is absorb by the boiler.
QUALITY:-
A boiler must be designed to absorb the maximum amount of heat release in
the process of combustion.

7. Fire in tube or hot gas send through
the tubes and boiler feed water in shell
side.
Fire tubes submerged in water.
Applications
It is used for small steam
capacities.
(up to 25T/hr and 17.5kg/cm2 )
Merits
Low capital cost and fuel
efficient(82%)

8. Water flows through the tubes
Water tubes surrounded by hot
gas.
Applications
For steam range 5.5 to 130T/hr
Used For power plant
Merits
Used as high capacity steam
boilers.
Demerits
Efficient control system need.
Capital cost is high.

9. It is comes as a complete
package that’s why it is
called package boiler. It is
generally shell type with
fire tube design,
Large number of small
diameter tubes leading to
good heat transfer.
It has higher thermal
efficiency compared to
other types boilers.

11.  Dry bottom furnace .
 Slag type or wet bottom type ,
 Oil fired furnace .

12. Boiler drum is the secondary part of the boiler where the water absorb the
heat and converted into the stream ,that steam send to the turbine after
reheating by the super-heater .

13. 1:- Heat loss due to un-burnt carbon.
{This loss can be reduce by using of proper grinded fuel}
2:- Heat loss due to dry flue gasses.
{This heat can be minimize by the completely utilize of heat of
flue gasses}
3:- Heat loss due to moisture in the fuel.
{For minimizing this loss we must use of dry fuel as possible
as}
4:- Heat loss due to surface radiation .
{we can minimize this heat loss by proper maintenance of the
furnace }

14. Combustion is a chemical reaction between fuel and
oxygen which results is release of heat.
~Oxygen is required to burn the fuel that is provides
from the atmospheric air.
REACTIONS :-
Carbon (C) + Oxygen (O2) Carbon-Dioxide(CO2) + Heat
Hydrogen(2H2) + Oxygen(O2) Water (H2O) + Heat

15. The Efficiency of Boiler May Be Defines by:-
A:- Combustion Efficiency.
“ This efficiency is related to the combustion of fuel and air
inside the furnace “
B:- Thermal Efficiency .
“ This Efficiency is related to the heat transfer to the water
inside the boiler drum”
C:- Fuel And Fluid Efficiency.
“It indicates the overall efficiency of the boiler inclusive
thermal efficiency of the heat exchanger , Radiation and
Convection losses output divided by input”

16. $ Direct Method:-

*100
$ Indirect Method :-
In this method we find out the total loss of boiler and then subtraction that
losses (%) from 100.
𝐵𝑜𝑖𝑙𝑒𝑟 𝐸𝑓𝑓𝑖𝑐𝑖𝑒𝑛𝑐𝑦 (%)=100 - Total loss(%)
