Peats ultimate analyses

It is for these reasons that we have initiated this correlative study of peat petrography and peat industrial-chemical (coal quality) properties. Note that the information reported herein represents preliminary results based on a limited number of different types of peats that were analyzed for only a few coal quality tests (i.e., proximate analysis, ultimate analysis, and BTU content). Future studies will involve measurement of other petrographic parameters and include other industrial analyses (such as, gas and liquid yields, physical properties, organic chemical yields, and so forth). 

Some wastes, which are combustible, are burned in a high-temperature furnace, like a boiler or incinerator. The heat released by the combustion process is recovered by producing high-temperature steam to supply heat or to drive a turbine to generate electricity. The heating values of some combustible materials are shown in Table ll.ll.26 The proximate analyses and heating values of municipal refuse, wood, and peat are listed in Table 11.12.26 If the ultimate analysis is known for a waste, the heating values can be estimated by means of Equation 11.44.

Representative Ultimate Analysis for Peat and Various Coal Types... 

Proportions of premacerals and botanical constituents composing selected peat samples from Minnesota, Maine, North Carolina, and Georgia were determined by microscopic analysis of oriented microtome thin sections. These results were compared with proximate and ultimate analyses of the same samples.
