This standard applies to solid biomass fuel.

2 Normative references

The following documents for the application of this standard is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. GB/T 21923 Test code for solid biomass fuels

3 Method summary

Solid biomass fuel combustion in the sample mixed gas stream of oxygen and water vapor and hydrolysis, the sample is completely converted to the chloride and chlorine quantitative Dissolved in water. Silver indicating electrode, a silver - silver chloride as reference electrode, the potential of the standard silver nitrate titration method directly from the condensed liquid chlorine Child, calculate solid biomass fuel chlorine content in accordance with standard silver nitrate titration solution consumption.
