Physical Properties of Rice Hull as the Fuel

Abstract

The authors measured the physical properties of rice hull which are considered to be useful for the future fuel and obtained the following results;
(1) Decrease values of volatile matter with respect to the temperatures took the maximum at around 250°C (Fig. 3).
(2) A locality differece was recognized in the ash content of the hull, while no local difference and little variation existed in the carbon.
(3) Average calorific values per dry matter and per non-volatile rest were measured as shown in Tab. 6.
(4) A negative correlation of calorific values against ash contents was recognized in the same groups of variety (Fig. 4).
(5) The uneasy volatile matter had a higher calorific value than the easy volatile matter, but this value was much lower than those of hydrocarbon gasses (Fig. 5).
