On the basis of the monitoring and testing method for energy saving of industrial boilers(GB/T15317-1994),the thermal performance test code for industrial boilers(GB 10180-2003) and the emission standard of air pollutants for boilers(GB 13271-2001),the heating power parameters of a biomass briquette combustion equipment under eight different working modes were investigated. This paper lays an important basis for designing and improving the biomass briquette combustion equipment.
Changes in energy content and biomass quality were studied in terms of dry weight and of carbon, nitrogen and energy content.
We used a combination of soil incubations, size fractionation and acid hydrolysis of SOM, [C], [N], and stable isotopic analyses, and biomass quality indices to examine how fertilization and haying can impact SOM dynamics in Kansan grassland soils.
Among the three groups of factors, climate and biomass quality had the most influence on decomposition rates.
Classification of the algal biomass quality by the agar industry is based on the apparent 'conchilla' content from visual examination.
Ergosterol production was followed as additional parameter of biomass quality.
