Good news and glory to God!
A larger-scale super turbo rice husk stove that injects super-heated steam into the burning chamber was recently developed for small cottage industry use. By injecting super-heated steam into the stove’s burning chamber, a luminous pinkish-flame, which is rich in hydrogen gas, is obtained. While cooking, the stove produces clean gas that is released to the atmosphere.
This technology is another breakthrough in biomass stove research and development of the Appropriate Technology Center of the Department of Agricultural Engineering and Environmental Management, College of Agriculture, Central Philippine University, Iloilo City. This project was collaboratively assisted by the following agricultural engineering students of CPU namely: Daniel Belonio, Lucio Larano, Ian John Fabellore, Mark Alvin Almazan, and Clark Ian Sansolis.
As schematically shown below, the stove consists of a conical hopper that is made of GI sheet no. 16 where rice husk is being fed for burning inside the combustion chamber, a 5 liter capacity steam tank which boils the water and converts it into super-heated steam, a combustion chamber cover having a diameter of 30 cm that also supports the steam tank, a 2-in. diameter air pipe which supplies the air needed for the combustion of rice husk, a char discharge lever that allows the removal of burnt rice husk during operation, a steam burner that is made of 2-in. diameter stainless steel pipe that ignites hydrogen gas from the steam, a 12-mm diameter round bar support to firmly hold the stove, and pot holder to support the cooking pot.
