FEATURES
(1)Coking in wider carbonization chambers enables clean production
and increases lumpiness and strength of the coke.
(2) By using negative-pressure operation and coal charging at
stamping side etc., no fume or dust emission will occur during the
whole process of coal charging, coking and coke pushing. All
generated raw gas will be burnt out and transformed into heat
energy to heat the coal cake and make it into coke. At the same
time, the waste heat is used to heat the boiler to produce steam,
which is used to drive the turbo generating units for power
generation.
(3)There is no complicated gas purification process, thus no
harmful waste water produced, hence clean production and sustained
development can be realized.
(4)Mechanical stamping or hydraulic stamping is adopted. The
hydraulic stamping machine has low noise and needs less
maintenance.
(5)The waste heat produced from coking can be totally used for
power generation to realize comprehensive utilization of the
resource.
(6)Low coke melting rate (around 2%). The carbonization chamber and
combustion chamber of the LRJ 2000 coke oven are totally separated
to reduce the rate of coke melting during the final period of
coking maturation.
(7)weakly caking coal can be blended into the coking coal, thus
saving the resource of the coking coal and reducing the cost of
coke production.
(8) Good utilization of thermal energy. carbonization and
combusting chambers are completely separated, with a distance of
only 100mm, and the heat produced (generated) from the gas burning
can be utilized by the neighbored carbonization chambers
(9)Big coke size, high strength and high thermal stability
(10) Less investment and short construction period. Since the
LRJ-2000 coke oven adopts vertical type carbonization chambers, and
technical improvements have been made on the structure of the oven
body such as refractory bricks, iron members, oven machines and
flues etc., the investment in capital construction has been saved a
lot. As per the situation of the current markets, the investment
(containing that for waste heat power generation) for the said coke
oven is approx. 50%-60% of that for a horizontal heat recovery coke
oven with the same capacity.
(11) Wider application of the technology. Thanks to the fact that
the profile and the mechanical equipment of the LRJ-2000 are
similar to modern chemical product recovery coke ovens, the
existing recovery coke ovens that are going to be closed or shut
down due to their heavy pollution can be modified into LRJ-2000
heat recovery clean type coke ovens by simply revamping the oven
bodies. .
(12) Less in power consumption and easy in operation. No such power
as steam or low temperature water is consumed during the production
process, and the consumption of water and electricity is low. Its
technological process is simple and hence it is easy to operate.
Less occupation of land area.
(13) There are less production process control points, for which it
is easy to realize automatic control and regulation through
computer.
