Award: Silver-PECIPTA 2022
The inclusion of hydrogen as an energy carrier for a renewable energy-based sustainable future required a major technological shift. In a quest to integrate the solid waste management sector, a systematic study has been conducted to investigate the feasibility of green hydrogen as a primary combustion fuel for waste incineration. The study is in continuation of our previous investigation on the hydrogen-based scale able and portable incinerators, where it has been concluded that the use of green hydrogen is feasible as a combustion fuel for incineration due to its high flame temperature and flame length. Herein, an improved design of a hydrogen-based modular incinerator has been presented for medium to large-scale applications. The improved design has a circular primary combustion chamber with detachable hydrogen burners located at the peripheral ring for uniform heat distribution.
Another improvement is the use of high-pressure air intake at the bottom of the combustion chamber specially designed to provide oxygen to assist combustion as well as to provide an air cushion to create a fluidized bed effect. Still another improvement is the use of a rotating grate to improve both ash collection as well as heat exposure of waste to high temperatures equally. An easy to operate two-door waste input assembly has been provided for waste input without exposing the operators or operating tools to high temperatures. The first waste intake chamber will also act as a drying stage for waste. Furthermore, a cyclone types secondary combustion chamber and sodium hydroxide solution containing tank have been provided to completely burn the remaining unburnt objects and carbon dioxide capture respectively.
