The main characteristic technologies are as
follows:
Coke oven asymmetric flue technology, single
oven pressure control technology, coal moisture control technology, CDQ and
waste heat power generation technology, etc.
Coke Oven Asymmetric Flue Technology:
By using the characteristics of fluid
dynamics, the waste gas box and flue are arranged on the coke side of the coke
oven, and the mixed gas and air inlet device is arranged on the pusher side of
the coke oven, so that the gas flow and air flow of the heating flues from the
pusher side to the coke side can be conveniently adjusted, the waste gas flow
can be conveniently discharged, and the longwise heating uniformity of the coke
oven is facilitated.
Single Oven Pressure Control Technology:
The coke oven adopts single oven pressure control
system to realize smokeless coal charging. The single coking chamber pressure
control can avoid the smoke and fire out of the coke oven and improve the
environment, the functions of high-pressure ammonia water for smoke elimination
and ground dedusting station can be replaced to reduce the investment and
operation cost, and simultaneously reduce the emission of raw gas.
Coking Coal Moisture Control Technology:
SDM independently developed a new
generation of patent technology of integrated coal moisture control and
crushing, which mainly uses the hot flue gas to make the moisture of coal
charged into the oven stable and controllable. This technology has the
advantages of other coal moisture control technologies as well as the following
unique advantages: simple and direct process flow, convenient operation, low
operation and maintenance cost, and low comprehensive energy consumption
Small occupied area, especially suitable
for the modification of existing production systems, basically no increase in
production operation and maintenance personnel
Low investment, 60~70% of other processes
under the same conditions
The system is safe and reliable, and has no
limit to the moisture content of the raw coal.

CDQ and Waste Heat Power Generation Project of Tangshan Rongyi Coking Gas Co.,
Ltd.
Coke Dry Quenching (CDQ)Technology:
CDQ uses cold inert gas (waste gas or
nitrogen after combustion) to exchange heat with hot red coke in CDQ furnace,
so as to cool and extinguish red coke and recover sensible heat of red coke, to
improve coke quality, reduce environmental pollution, save energy and reduce
emissions.
