| Make Gas & Kerosene last longer |
| |
| Do you know that housewives can save upto
30% of cooking gas or kerosene by following a few simple ‘fuel–saving
tips’?
We at PCRA have conducted a series of experiments on how
to save cooking gas or kerosene. This was done in collaboration
with the Indian Oil Corporation Ltd. (R&D Center), and
the Institute of Hotel Management and Catering & Applied
Nutrition, NEW Delhi. Our experiments have revealed that it
is possible to save upto 30% of cooking gas or kerosene by
following good cooking practices. It will be surprising to
discover that certain cooking habits cause substantial waste
of fuel.
Given below are a few tips on how to minimize losses and
get value for the money you spend on cooking gas or kerosene:- |
| |
 |
A few minutes of planning
ensures a big fuel saving |
| |
Every thrifty you can avoid an idle flame if you
prepare and keep all materials required for cooking
within reach, before lighting the stove. Experiments
have revealed that keeping the flame of the larger burner
burning unnecessarily in a gas stove, results Even a
few paise saved everyday will amount to a sizeable saving
by the end of a month. |
| |
 |
| |
Remember
Light your stove only after you have kept all the ingredients
within your reach and ready for cooking. Put off an
idle flame at once. |
|
| |
|
| |
| Pressure cooking saves fuel |
 |
| |
Pressure cooking is one of the fastest and most economical
ways of cooking. Experiments have shown fuel (kerosene
or cooking gas) savings of 20% on rice, 46% on soaked
gram dal and 41.5% on meat, as compared to ordinary
cooking. The savings in cooking time were equally high.
To obtain further savings from a pressure cooker, use
the separators of the cooker to cook different items
such as rice, vegetable and dal, all at the same time.
Just think of the fuel and money you will save! And
have your entire meal ready quickly. |
| |
 |
| |
Remember
Pressure cooking saves duel and time. Use separators
in the pressure cooker to cook different items at the
same time. |
|
| |
|
| |

|
Use optimum quantity of water |
| |
The quantity of water used differs for various dishes.
And even for the same dish, different housewives use
varying quantities of water. Since water is extensively
used in cooking, you should remember that surplus water
wastes fuel. Besides, when the excess water is drained
subsequently, precious nutrients are lost. An experiment
on cooking rice with double the required quantity of
water has revealed that fuel consumption increased by
65% So use only the optimum quantity of water for cooking. |
| |
 |
| |
Remember
Surplus water consumes additional fuel which could otherwise
be saved. |
|
| |
|
| |
| Reduce the flame when boiling
starts |
|
| |
When a vessel’s contents reach boiling point,
a low flame is enough to keep them boiling. Addition
of more heat at the boiling stage causes further evaporation
of the liquid without serving any useful purpose. Hence,
when water or any other liquid is boiling, reduction
in the flame will reduce wastage. This is possible in
a gas stove by turning the know to ‘simmer’
position or in a kerosene stove by lowering the wicks.
Experiments conducted have revealed a saving of 25%
fuel when the flame was reduced after boiling had started.
Try it yourself. You will find that the time taken to
cook is just the same. |
| |
 |
| |
Remember
Always reduce the flame once boiling starts. |
|
| |
|
| |
|
Soak before cooking |
| |
Experiments have shown that soaking ingredients such
as dal and rice for various intervals of time before
cooking saves fuel. 250 gms of kabuli chana (chick peas)
when soaked overnight in water consumed 22% less fuel
as compared to the fuel required for the same quantity
of unsoaked kabuli chana. |
| |
 |
| |
Remember
Sizeable savings in fuel are possible if you soak cereals
in water before cooking. |
|
| |
|
| |
| Shallow, wide vessels save
fuel |
|
| |
A visible flame touching the sides of vessel wastes
fuel since it gives out heat to the surroundings. But
if you cover the flame as much as possible by using
a broad vessel, you will save fuel. Our tests have established
that for most stoves, a vessel of 25 cm. Diameter is
ideal for cooking. A vessel of this diameter tends to
cover the flame completely. Where a narrower vessel
cannot be avoided, try and reduce the flame so that
it does not creep up on the sides of the vessel. |
| |
 |
| |
Remember
Hide the flame with broad bottomed, vessel. Do not use
vessels which are narrow as they allow the flame to creep
up on the sides. |
|
| |
|
| |
|
Put the lid on heat losses |
| |
It is a good practice to cover cooking vessels and
pans with a lid, as an open vessel loses heat to the
atmosphere which means a waste of fuel. A vessel of
100sq.cm. opening , containing not water at 96°C
would waste 7.2 GMs Of gas per hour. The heat loss would
increase by 2-1/2 times if there is wind blowing through
the kitchen. If the vessel is covered by a lid , the
heat loss would drop appreciably to 1.45 gm. Of gas
per hour as heat is retained within the vessel. |
| |
 |
| |
Remember
Always place a lid on an open cooking vessel or pan. |
|
| |
|
| |
| The small burner saves fuel |
|
| |
A cooking gas stove has a big burner and a small
burner. The small burner consumes 6% to 10% less gas
than the big burner ! An experiment on cooking 250 GMs
Of potatoes revealed that the small burner consumed
6.5% less gas but look 7 minutes more than the big burner.
Similarly in a kerosene stove, by cooking at lower flame
you will use less fuel. You can now imagine how much
fuel is being avoidably wasted.
True, the small burner of the lower flame takes a little
more time to complete cooking, but then you are not
always in such a hurry that you can afford to waste
fuel. |
| |
 |
| |
Remember
Use the small burner or lower flame more often, as the
case may be especially when you have time to spare. |
|
| |
|
| |
|
A clean burner helps save fuel |
| |
It is important to/clean the burner of your gas range
regularly and trim or replace the wicks of the kerosene
stove. Soot clogged gas burners and charred wick-ends
of a kerosene stove increase fuel consumption. Regular
maintenance of your stove helps you save fuel. In case
stove knobs do not more freely, get them attended to. |
| |
 |
| |
Remember
A bright, steady blue flame means efficient burning.
If you see an orange, yellow on non-uniform flame, clean
the burner or wick as the case may be. |
|
| |
|
| |
| For additional saving |
|
| |
The use of ‘ISI’ marked kerosene wick
stoves in place of non-‘IST’ marked stove
saves upto 25% of kerosene and the use of higher efficiency
‘ISI’ marked LPG stove (the thermal efficiency
level of which is 68%+) saves upto 15% of gas. |
|
| |
|
| |
|
Clean vessels help too |
| |
A coating of undissolved salts is usually found on
the insides of kettles and cookers. Even a millimeter
thick coating can reduce the flow of heat to the vessel’s
contents. This increases your fuel consumption by as
much as 10%. |
| |
 |
| |
Remember
Cooking vessels should always be scrubbed clean. |
|
| |
|
| |
| Allow frozen food to reach
room temperature before cooking |
|
| |
Cold milk, frozen meal or any other cold food-stuff
from the refrigerator should not be taken straight to
the cooking pot. Keep it out of the refrigerator should
not be taken straight to the cooking pot. Keep it out
of the refrigerator for some time before putting if
on the stove. Very cold food consumes a larger amount
of fuel. |
|
| |
|
| |
|
Plan your meal timings |
| |
If all members of the family eat together, which
signifies togetherness and increases joy, frequent reheating
of food before serving can be avoided. If eating together
is not possible, store cooked, hot food in insulated
containers to serve it hot later. |
