measurement of heating value of rice husk by using oxygen

Measurement of Heating Value of Rice Husk by Using Oxygen

The maximum higher heating value of rice husk, i.e. 15944±55 J/g, is obtained when the mass ratio of rice husk and benzoic acid is 1.2:1. At high mass ratio of rice husk and benzoic acid, e.g. 2:1, due to the weak effect of combustion adjuvant [10], lower measured higher heating value is obtained.
