COAL ANALYZERS
C
10 patents (7 Invention patents), the only type of
elemental analyzer which can replace the combustion
crucible automatically
ELAn-35, Carbon Hydrogen & Nitrogen Analyzer
ELAn-35
Application:
Carbon Hydrogen & Nitrogen Analyzer can be used to
determine the the carbon, hydrogen and nitrogen content
in coal, coke and other combustibles.
Conformance with Standards:
15029541 Solid mineral fuels Determination of total carbon,
hydrogen and nitrogen content Instrumental method
ASTM D5373-02 Standard Test Method for Instrumental
Determination of Carbon, Hydrogen. and Nitrogen in
Laboratory Samples of Coal and Coke
61311-476-2008 Standard Test method for Determination of
Carbon and Hydrogen of Coal
No disassemble or cooling required, easy to
replace the combustion crucible.
For the elemental analyzers, the combustion residues
will remain in the combustion crucible, after some
quantity of tests (about 100). it needs to be replaced.
For other brands. it is complex and time wasting,
operators need to wait for the furnace cooling down
and disassemble the analyzer, then replace the
crucible manually. For us operators only need to click
on the software, the crucible to be replaced will be
presented from the combustion furnace to the
crucible replacing door automatically. Once the
crucible is replaced, tests can be conducted
immediately.
Convenient to replace the reagent furnace
Separate design of combustion furnace and reagent
furnace makes the replacement of the reagent easy
and convenient.
Ultra-low drift infrared cell and thermal
conductivity cell
With high-performance infrared light supply and
superior optical glass, precise thermostatic control as
well as pure gold infrared path, the drift of the
infrared cell and TC cell have been optimized which
are developed and designed by US.
Low operation cost
Purity oi 9915% oxygen and nitrogen can meet the
test requirement.
During the test. He consumption is only 0.7L/min.
High automation
Up to 34 samples can be loaded and after that,
operators can be freed for other tasks. The analyzer
will finish the whole test automatically.
Improved test precision
Samples are carried into the combustion furnace
by oxygen blow, which can make sure all the gases
obtained by combustion are collected into the gas
chamber to improve the test precision.
Shorten preheating time
Preheating time is less than 2.5 hours.
Easy to handle
●
Easy-to-use Windows -based software.
●
Easy data handling, rear time data can be
transmitted through internal network.
●
With CAN bus interface, several elemental
analyzers can be controlled by a single PC.
●
Connect with balance and network by standard
interface RS232.
