A Study on Methane and Nitrous Oxide Emissions Characteristics from Anthracite Circulating Fluidized Bed Power Plant in Korea

Table 2

Repeatability of elemental analysis for carbon (C) and hydrogen (H) in coal.

Times	Sample type	Injection weight (mg)	Element content (%)
			C	H
1	BBOT	1.686	72.53	6.09
	Unknown^1	1.832	72.90	6.04
	Absolute difference (%)		0.37	0.15
2	BBOT	1.686	72.53	6.09
	Unknown^1	1.832	72.63	5.84
	Absolute difference (%)		0.10	0.25

¹Unknown is that using the same BBOT sample but not inputting the information of the sulfanilamide element content.
