1. Improved Cook Stove (ICS)
Journey to Intelligent Green Cooking

2.  A stove is the combination of heat generation and heat
transfer to a cooking pot .
 Cook stoves are commonly called “improved” if they are
more “efficient” than the traditional cook stoves.
 “Efficient” mean Energy efficiency
 The core question concerning the efficiency of two
alternative stoves is: “With which of the two stoves do I use
less fuel to prepare my meal?”

3. These stoves may be built under ground
or over ground.
Heat transfer to the cooking pot is very
low, resulting into low efficiency.
Mud-built cylinder with three raised
points.
Because of the large size of the flue gas
exits lowering conventional heat transfer.
Emits smoke, which affect the health of
the users
Incomplete combustion of biomass fuel
TRADITIONAL COOKING STOVE

4. DIFFERENCE BETWEEN SMART ICS
WITH TRADITIONAL COOKING STOVE
Issues Traditional ICS Smart ICS
Heat Trapping No
Yes through sealed body
with glass wool and black
coated outer side of inner
body
Self Heat Consumption
Yes, made of cement, sand
and crushed brick, these
material consumes heat
faster and release faster
Negligible amount as SS
sheet is used
Corrosion Problem
Yes, cause dimension
change of body, air inlet/
Outlet and feed holes
No

5. DIFFERENCE BETWEEN SMART ICS
WITH TRADITIONAL COOKING STOVE
Issues
Traditional cooking
stove
Smart ICS
Installation Type
Most are fixed, site
selection is important
Portable
Ready to go
After installation required
certain time for ensuring
dry stove is thoroughly
rubbed
Ready to use immediately
Body fracture/crack
Required smoothen the
ICS body with mud or
cow dung at least twice a
week
No such problem

6. DIFFERENCE BETWEEN SMART ICS
WITH TRADITIONAL COOKING STOVE
Issues Traditional ICS Smart ICS
Chimney Clogging
Problem
Yes, required cleaning
once in a week
No cleaning required
Dimension Change
Problem of Air inlet/Feed
hole
Yes, Due to the corrosion
of cement or mud the air
inlet or feed hole
dimension may change,
result of improper
combustion
No

7. TYPES OF ICS
A) Fixed:
i. Single stove with filter plate
ii. Single stove without filter plate
iii. Double stove with chimney
iv. Double stove without chimney
B) Portable:
i. Single stove with filter plate
ii. Single stove without filter plate
iii. Double stove without chimney

8. COMMON PROBLEMS OF EXISTING ICS:
Required installation, hence additional cost of installation, labour
charge are concerned issues.
After installation required certain time for ensuring stove is
thoroughly rubbed else wet and partially damp stove consume large
amount of fuel and flexibility.
improper combustion, excess firewood use

9. COMMON PROBLEMS OF EXISTING ICS:
Chimney blockage by deposition of soot on the inner wall and cause
flame and hot flue gas coming out through feed hole during cooking
instead of releasing through chimney.
Body fracture/crack due to heat pressure after continuous use of stove
for a week.
Required smoothen the ICS body with mud or cow dung after 5-7 days
of use for preventing body corrosion.

10. COMMON PROBLEMS OF EXISTING ICS:
Advance preparation of cooking stuff is required, so after cooking one
item immediately another item has to place in stove to save energy of the
stove. (Heat trapping system absent).
For double mouth ICS both mouth should be in use cooking at same
time whereas it is tough to manage cooking simultaneously in two
mouths.
After using for long time, the diameter of hole of grate becomes larger,
as a result some piece of firewood will fall down through the grate
without burning, which ultimately increase the fuel use.

11. FACTORS BEYOND THE DESIGN CONCERN
Heat transfer into the pot & Heat Trapping
Handling of the fuel
 Handling of the stove
Management of the cooking process
Cooking environment

12. TEN DESIGN PRINCIPLES
Principle-1: Whenever possible, insulate around the fire using lightweight,
heat-resistant materials.
Principle-2: Place an insulated short chimney right above the fire.

13. Principle-3: Heat and burn the tips of the sticks as they enter the fire.
Principle-4: High and low heat are created by how many sticks are pushed
into the fire.

14. Principle- 5: Maintain a good fast draft through the burning fuel.
Principle-6: Too little draft being pulled into the fire will result in smoke
and excess charcoal.

15. Principle-7: The opening into the fire, the size of the spaces within the stove
through which hot air flows, and the chimney should all be about the same
size.
Principle-8: Use a grate under the fire.

16. Principle-9: Insulate the heat flow path.
Principle-10: Maximize heat transfer to the pot with properly sized
gaps.

23. SALIENT DESIGN FEATURES
Robust design with dual body layer to constrain heat inside the
burning chamber for long time.
 Efficient insulating material : glass wool (Thermal conductivity: 0.04W/m.K) is
used in the middle of the dual bodies to isolate outer body from adjacent chamber
body hence heat transfer through stove body is baulked.

24. SALIENT DESIGN FEATURES
Inner body containing burning chamber is coated black in
outer surface to keep maximum amount of heat inside the
chamber.

25. SALIENT DESIGN FEATURES
 Intelligent smoke outlet system engineered to prolong smoke
exertion from the burning chamber and forged to maximize the
existence of heat into the stove.

26. SALIENT DESIGN FEATURES
Separate feed hole and air inlet with insulated door make efficient
heat collapsed stove.

27. SALIENT DESIGN FEATURES
 Perforated fuel carrier, which stands at the middle of air inlet.
Therefore, easy access of air to fuel wood for ensuring optimal
combustion of fuel wood hence maximizes the stove’s efficiency.
 Additional water boiling system is adjusted with the system, where
smoke exerting from burning chamber is maneuvering to heat the
water for using extend purpose.

28. SALIENT DESIGN FEATURES
This tank is also constructed with dual part where inner body is coated
black outside for storing heat inside. Moreover, this additional part can be
used for ordinary heating, boiling of food preparation.
After heating tank body smoke is proceed to flow through long chimney
(78 inch) to ensure releasing clean smoke to the environment.
