TECHNOLOGY

The machineries e3coal will use in their facilities are build in the UK. All equipment regarding the heat process is coming from CDS Group based in Stoke-on-Trent UK. 

CDS was Founded in 1983 by  current Chairman Terry Dunne, CDS originally specialized in devising complete ceramic drying solutions for a range of organizations and remits. It has always been our ethos to work on projects from their initial planning stages through to final completion; this has allowed us space to innovate, delivering products that supersede industry trends by their very design.

It’s this commitment to continual redevelopment that has lead to us being recognised as a worldwide authority in the field of thermal processing technology.

 

At the forefront of thermal technology innovations and developments, CDS has developed, patented and introduced into the marketplace a ‘new’ concept in process drying “R-O2 Technology”

Using dry superheated steam as the heating medium to replace the traditional air/oxygen methods of drying. This dramatically improves the efficiency of the drying process whilst at the same time using a safe, invisible dry gas being used at atmospheric pressure.

The R-O2 thermal advantages are revolutionizing the process drying industry. Achieving validated energy saving against conventional systems, minimal percentage drying losses of product and tremendous advantages in drying cycle times and efficiencies.

WHAT IS R-O2 DRYING?

R-O2 dryers are uniquely designed to operate in either a conventional mode or super heated steam mode, or a combination of both to optimize the drying cycles.


R-O2 Drying Advantages include:-

  •  Specific heat of steam is twice that of normal air, hence it can transfer more than twice the amount of heat for the same mass air flow.

  • Viscosity of steam is approximately half that of air at the same temperature creating a much greater effect, in particular on difficult shaped products.

  • R-O2 dryers, are designed to operate in a direct ring mode if required. A fully modulating air valve is added to the burner to give stoichiometric control and minimize the oxygen input into the system during the main drying phase.

HOW DOES STEAM REPLACE AIR?

  • The steam is generated from the moisture contained only within the product.

  • When water boils & becomes steam its volume increases by a factor of 1,670.

  • As the water evaporates, each Kg of water occupies a volume of 1.67 m3.

  • R-O2 Dryers operate on full recirculation so no new air is required to enter the system.

  • As both the recirculation mix and the product get hotter, 1.67m3 of increasingly humid air is vented as each Kg of water is evaporated. This process continues until the Dryer is virtually free of air which is replaced with dry superheated steam.
