Stand-alone CWSF production unit is a unique development from Amalthea-Service and Effective Energy Technologies GmbH (Austria). Unit has low-energy consumption for producing CWSF and characterized with stable CWSF characteristics and wide range of possible coals.
Amalthea-Service proposes new 'production+combustion' solution which includes equipment and services for swithicng from coal to CWS. Solution is targeted for 
Rotary-pulse apparatus (RIA) is designed for processing liquids, pastes and slurries. In the purpose of CWS production it used for preliminary water activation which is pass to wet-milling device.
Steam/Air atomizing nozzle
Swirl furnace 'Tornado' is developed for high-efficient Coal-Water Slurry combustion in a boilers of different models and design.Prepapring
CWSF is prepared as a result of crushing and consequent milling of raw coal, mixing it with water and (if required) additives.For crushing and milling of raw coal standard crushers and mills are used. For mixing of fine dispersed coal with water modified mills and mixing devices are used.
Major CWSF characteristics are below:

|
Value |
|
Part of coal |
58...70% |
|
Coal particles in CWSF |
250mkm - <97% |
|
Density, ρ |
About 1200 kg per cubic meter |
|
Ash |
5...50% (зависит от марки угля) |
|
Calorific value |
2900...4300 kcal/kg depending on initial coal |
|
Viscosity |
0.7...1.2Pa*s-1 |
|
Ignition temperature |
450-500°С - CWSF from brown and gas coals 550...650°С - CWSF from forge and athracites |
|
Incineration temperature |
950...1100 °С |
|
Stability |
from 30 days |
If CWSF produced from law-ash coals it could be used in gas/oil boilers without needs to install ash removing system. Low-ash CWSF could be also produced by processing of initial CWS.
