Performance Evaluation and Characteristics Co-product of Energy Efficient Institutional Bio-Char Rocket Stove

The vast majority of improved cook stoves, built today are for domestic cooking, often used by single families or households. However, there are also universities, colleges, hospitals, prisons, factories and large temporary settlements such as refugee camps or sites of religious festivals where a large number of people may need to be fed. This study was to evaluate performance of the stove for institutional cooking and characteristics the stove co-product (bio-char production) for soil amendment. The stove used as to pyrolysis of woodchip to form multi-face exhaust holes syngas flow to stove combustion chamber. Gasses start to come out from the pyrolysis chamber through the exhaust outlet after 8 minutes of pyrolysis, and pressurized the gasses come out at this time, it start burn in combustion chamber. After 20 minutes the water boiling was completed, the biochar had 4.634 PH value. At 60 minutes pressurize Syngas was stop and gives low combustion. The char was tested and found to be rich in carbon with a Ph of 7.235 and 1.35kg (30.17%) yield when syngas burn upto 60minutes. The results of experiment show that the fuel consumption 8.75kg, and overall Thermal efficiency 45.67% of stove and the bio char produced is good for amendment of soil and it was burnt at very high temperature.
