Problem Addressed
Traditional bukharis (heating systems) may cause lung infections, breathing problems, and carbon monoxide poisoning. Their cost and maintenance prove challenging, with charcoal or fuel wood being burnt inefficiently.
Technology
Firewood is placed on a preheating tray to dry for cleaner burning and ignited through a door above. The heat generated is distributed evenly across the room. Around the rim of a copper water tank are vertical rods containing heat-retaining indigenous clay. The room is heated evenly, from 0 to 20 C within five minutes. Flue gases warm up the water to be used for various purposes. The innovators have also modified it to be used as a stovetop.
Societal Impact
The Advanced Portable Bukhari remains warm for a longer time using less fuel. This three-in-one model is capable of burning charcoal, wood and waste oil, the latter being almost smokeless.
Current status
They were awarded by NIF for their earlier innovative Bukhari, which has been improved in this version. To scale their efforts, they established Rafiq Innovations Pvt. Ltd. to manufacture and market their innovations.
