バイオマス固体燃料の実用的な発熱量推定法

In order to promote the use of biomass, we derived an equation for estimating the calorific value of biomass solid fuel with varying water content, taking into account the presence or absence of ash and its amount. The usefulness of the derived estimation equation of calorific value was verified using sugi sawdust and fermented poultry manure samples. As a result, the estimated gross calorific value obtained from the estimation equation of calorific value derived using the measurement results of sawdust and poultry manure in the initial condition agrees very well with the gross calorific value of the samples with and without ash, whose water content was changed by drying sawdust or pelletizing poultry manure. From the above results, the usefulness of the derived estimation equation of calorific value was demonstrated, and using this equation, it was clarified that the gross calorific value of the biomass solid fuel at any water content could be estimated. In addition, by using the derived estimation equation of calorific value for the gross calorific value of the sawdust sample on a dry/ash-free basis and the ash content ratio of the poultry manure sample on a dry basis, the gross calorific value of the fermented poultry manure at any water content could be estimated to some extent.
