Handling firewood is not an easy task. It needs years of experience and patience plays a huge part! But what is purchased makes a huge impact in the performance of the institutional improved cook stove (IICS)
Firewood suppliers may deliver fuel that is unsuitable for efficient combustion. Wet or oversized wood reduces the performance of the rocket IICS, increases smoke emissions, lengthens cooking times, and leads users to believe that the stove is not performing as intended.
Another challenge is ensuring consistency of supply. Firewood availability changes with the seasons, especially during rainy periods when drying is more difficult. Suppliers may initially provide high-quality dry wood but later substitute it with freshly cut or partially dried wood to meet delivery schedules. This inconsistency affects kitchen operations and makes fuel consumption unpredictable.
Selecting the lowest-priced bidder does not always produce the lowest cooking cost. Cheap, low-quality firewood often contains more moisture and less usable energy, meaning larger quantities are required to cook the same meals. Schools may therefore spend more over time despite paying a lower purchase price. This is why at Simoshi we not only train schools to build a storage place for their firewood , preparing their purchases well in advance to ensure the appropriate drying time is provided, but also consider fuel quality and energy value with the same importance as that of the initial cost.
