Improving High Altitude Habitability and Sustainability
The new Bukhari, designed and developed by DIPAS (DRDO), is a kerosene-fueled, safe, and efficient vented space heating device.
- Multiple level safety against back-draft-generated blasts.
- Back-draft resistant exhaust vent.
- Three impact braking plates between two chambers.
- No auto-ignition of the burner if extinguished.
- No build-up of harmful gases and fumes in the room.
- Uses only 500-700 ml kerosene/hr.
- Maximal extraction of heat, no thermal wastage in exhaust gases.
- Keeps the room comfortably warm by both convective and radiative heating.
- Each bukhari prevents about one ton of CO2 and 0.3 tons of black carbon per year from going to the environment.
- Two chambered designs, one for hot air blower and the other for flue gases.
- The hot air is circulated in the room with the help of a DC fan that is operated with power generated from a solar panel and stored in a small battery.
- An improved maintenance-free exhaust vent has been provided, which works on Bernoulli’s principle and does not allow air coming from any direction to extinguish the burner and thus prevent a fire hazard.
- For efficient heating, a three-burner stove has been developed that can also be used for cooking or warming food, heating water etc.
- Controllable blue flame, so no soot formation.
- Bukhari has been designed to extract maximum heat so that there is less wastage of heat at the exhaust level.
