Traditional cooking fires have several problems including fire spreading outside the cooker, low thermal efficiency requiring more fuel, smoke making pots dirty and causing indoor air pollution, and only allowing one pot to be used at a time. Smoke from traditional rural kitchens causes eye problems, lung problems, and death for 500,000 women and children in India each year. The Firenzel Unnat Chulha is a smokeless stove that is lightweight, fuel efficient, saves 70% on fuel costs, and burns wet wood. It has higher thermal efficiency and lower CO/CO2 ratios than traditional mud stoves.

1. Traditional stone cooking fire-Problems?
Fire touches bottom of pan
Fire spreads out of cooker
Thermal efficiency is 5 to 15 %.
Take more time to cook so needs
lots of fuel.
The smoke makes the cooking pots dirty
this increases the work load of women.
Smoke entering into the kitchen room leads to
‘Indoor air Pollution’( IAP)
Every year IAP is responsible for the death of 1.6 million people - that's one
death every 20 seconds
This creates a risk of burns and
scalds.
Only one cooking pot can be used at a time.
