The specification discloses a proximate analyzer for the analysis of fossil fuels such as coal and coke. The analyzer includes a temperature-controllable and atmosphere-controllable furnace chamber, a balance having a weigh platform positioned within the furnace chamber, and a platter positioned within the chamber and adapted to support a plurality of sample-containing crucibles. The furnace further includes means for continuously depositing the crucibles in a predetermined sequence on the weigh platform and means for monitoring the weights of the crucibles to determine when analysis is complete and for calculating the proximate analysis results based on weight loss. A method of proximate analysis using the proximate analyzer is also disclosed.

A fossil fuel proximate analyzer comprising: a furnace; a balance having a weigh platform positioned in said furnace; support means for supporting a plurality of crucibles in a generally horizontal, circular configuration, each of the crucibles holding a sample of a material to be analyzed; oxygen line means for selectively flooding said furnace with oxygen to facilitate oxidation of the samples during analysis, said oxygen line means including a first end to be coupled to an oxygen source, a second end communicating with said furnace, and a valve means between said first and second ends for controlling the flow of oxygen through said line means; rotation means for rotating said support means to sequentially vertically align the crucibles with said weigh platform; elevator means for vertically shifting said support means to deposit and remove the aligned crucible on and from said weigh platform; control means for controlling said rotation means and said elevator means to repeatedly weigh the crucibles sequentially; circuit means connected to said balance for monitoring the weights of the crucibles to monitor the weights of the samples, said circuit means including means for determining when the weights of the samples have reached a generally constant value indicating that a proximate analysis step is complete.
