At CSIR-NEERI (National Environmental Engineering Research Institute), NEERDHUR, a multi fuel improved cookstove has been developed with high overall thermal efficiency, reduced fuel consumption and reduced emissions through design improvements and technological innovations.
Its USP is that besides wood it can consume several fuels including coal, cow dung, charcoal, biomass and other agricultural residue. Designed as a hybrid with technology innovations, it uses much less fuel with lower emissions.
At present, NEERDHUR cookstoves approved by MNRE on the basis of their performance testing conducted by Improved Cook-stove Test Centers and satisfying stipulated performance parameters.
NEERDHUR is 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 among the best cookstoves in terms of thermal efficiency under the 2KW domestic natural draft biomass stoves
