The Global Burden of Disease 2010 ranked air pollution as a leading cause of death and disability in India accounting for 9% of the national disease burden. Availability of free biomass and agriculture residue will be an important reason for continued use of cookstoves among poor rural household. Hence, CSIR-NEERI has developed a domestic natural draft multi-fuel improved cookstove (ICS) “NEERDHUR” by adopting a comprehensive approach of technological innovations for improved stove efficiency, emission reduction and intensive stakeholder interactions to address issues of adoption such as stove cost, stove maintenance, fuel affordability, and availability. The NEERI stove “NEERDHUR” addresses adoption and sustainability related challenges of ICS. It is a multi-fuel (biomass, charcoal, agro residue etc.) stove with hybrid operation modes. NEERDHUR has been extensively tested in the lab and field for user’s perception and acceptability.
At present, NEERDHUR Cookstove is approved by MNRE on the basis of their performance testing and certified to meet the newly developed cook-stove emission standards by Bureau of Indian Standards (BIS 2013). NEERDHUR shows a thermal efficiency of 33.33% with emission levels as CO: 3.78 g/MJd, TPM: 340.10 mg/MJd at a power output of 1.70KW. NEERDHUR is rated best among the MNRE approved Cookstove in terms of thermal efficiency under the 2KW domestic natural draft biomass stoves.
Social Outreach and Implementation Status:
Know-how of “NEERDHUR” Improved Cookstove technology has been successfully demonstrated in 10 villages across 4 states, namely Maharashtra, Madhya Pradesh, West Bengal and Gujarat. Field trials and IEC have also been done in the above states.
- Total number of States covered : 4 (10 villages)
- Total Households Benefitted : 800+
- Total Beneficiaries : 4000+
Also, a detailed cost analysis has been performed for NEERDHUR: Domestic and benefit-cost ratio was found range between 9.1 and 22.6
CSIR-NEERI has also developed a community cook stove named NEERDHUR Community. This community stove is also approved by the MNRE, Govt. of India on 20.07.2017 after satisfying stipulated performance parameters and is certified to meet the newly developed cook-stove emission standards by bureau of Indian standards (BIS 2013). NEERDHUR shows a thermal efficiency of 28.37 ± 0.73% with emission levels as CO: 2.64g/MJd, TPM: 310.40 mg/MJd at a power output of 7.06 kW. NEERDHUR Community gives highest power output under the community natural draft biomass stoves. Ready for technology transfer and dissemination.
