Re: Drying Of Coking Coal
We have done a lot of work in fluidized bed drying and this technology would likely help you here. It is continuous and can be designed for high throughputs. I note that the particle size distirbution of the coal is quite wide, which can impact bed hydrodynamics and the drying uniformity. Hence the dryer would require some careful design and operation. Conical vessels can help in this regard to assist with bed turnover while reducing particle entrainment. ■

Dear Johan,
We have expirience on big dryers in minery industry.
Normally when we do the pre-project we calculate the sieze of the installation, the consumptions operating costs and the installation prices.
I attach you a catalogue of our dryers equipments (thera are not indicate the big sizes).
If you want more information don't hesitate to contact us to

Drying Of Coking Coal
Dear Mr. van de Vijver,
NLI products as, supply indirect steam dryer units for continous processes within the mineral industry.
For our drying process your 1st option is preferrable, due to grain sizees. The smaller particles, the better heat transfer ratio and hence smaller dryer units.
We have experience with drying of low rank coal (Lignite).

Re: Drying Of Coking Coal
Please contact with us. Our new coal drying technology is going to apply for patent, we can only give you the following features now:
1, lowest energy cost
60-75% of net energy can be saved, compared to conventional dryer.
2, emission reduction
3, higher drying rates, shorter drying time
4, fire and explosion risk free

Lf Pumping - Ultimate Dryer Of A Growing Range Of Materials
With energy prices set to rise over the next 5 years, we know this system will be of great interest to you, either as a pre-dryer for your existing drying systems or as a standalone drying, pumping or material handling unit.
The key Points associated with this unique environmental system, compared to any known rotary, ventura, vibrating fluid bed, or static fluid bed drying systems for materials are:-
•Guaranteed energy savings, as there is no requirement for any gas, gas/oil or diesel fuels, to generate heat source to dry materials.
•Reduced carbon footprint.
•Operational advantages throughout the transportation, drying, and delivery process.
•Compact size.
•Guaranteed Low maintenance costs.
•Minimal disruption of integrating system in to current process line.
•Liquids, sludges, and aggregates up to 75mm.
•Bespoke systems can dry sand from 60% moisture content down to 0.3%.
•Bespoke systems can handle up to 500 tonnes per hour.
We have been specifically been working with a number of coal power stations in the UK, crushing and drying coal, in vast quantities.
What materials can be dry, pump, or material handle? http://lfpumping.com/material-handling.php
We are confident that this system offers to you the very latest cutting edge technology, packed with financial and delivery savings. We look forward to discussing all your transporting, drying, crushing, and grading applications. ■
Microwave Dewatering
Hi,
It could be worth considering microwave de-watering.
See www.drycol.com I can help if you have any questions.

Drying of coking coal
Drying of coking coal
I started a feasibility study for the application of a CMC (Coal Moisture Control installation) in our coking plant.
Here in Europe, as far as I know, there are no CMC-plants in operation, so I ask for your help.
Data of our coking plant:
2 batteries with in total 100 ovens
Coke production = 1.27 Mton / year
Coal use = 1.6 Mton / year
Moisture content = 7.5 to 11%, we want to reduce this to 6% continuous.
Coal blend consists of 8 coal types,
1th option is after crushing:
Coal conveyor line capacity = 400 ton/hr in service 12 hours / day.
average conditions (2007):
H2O= 9% average, minimum = 7.2%, maximum = 10. 5%
Grain size < 0,150mm = 15.5%
Grain size 0,15 / 0,21mm = 6.4%
Grain size 0,21 / 0,50mm= 18.5%
Grain size 0,5 / 1mm = 16%
Grain size 1 / 2mm= 15%
Grain size 2 / 3,15mm= 12%
Grain size 3,15 / 4,5mm = 9%
Grain size 4,5 / 5,6mm= 2.7%
Grain size> 5,6mm= 5.1%
VM (Volatile Matters) = 22.5%
Ash= 8.1%
S= 0.69%
2nd option:
Placing a CMC before the coal silos and dry also the coal for the powder coal injection of our blast furnaces. The capacity of the conveyor belt is 1500 ton/h. discontinuous. The grain size varies between 0 – 50mm
Who can help me with information?
- information of drying coking coal?
- Where are CMC-plants in operation.
- Information about the influence of pr-drying the coal blend and the effects on the coking process.
- the energy consumption,
- the costs of
- a complete installation, maintenance & operational costs
Thank you for your help
