Technology Overview

Carbon Slurry Fuel (CWS)

CWS is a liquid mixture of finely milled coal or other carbonaceous materials with water or an aqueous emulsion:

CWS = Coal (58% ... 70%) + emulsion (29% ... 40%)

Usage of oil-based and organic water emulsions improves CWS calorific value.

CWS has almost the same viscosity as masut (Heavy Fuel Oil) what makes it suitable both for pumping on short and long distances and for spraying into a boiler via specially designed nozzles. Gas, oil/diesel, coal still could be used as a redundant fuel for boilers.

Raw materials for CWS Coal of most types: brown, gas, long-flaming,

skinny, anthracite

Carbonaceous Raw Materials: pyrocarbon (carbon after pyrolysis of tires, rubber), petroleum coke, etc.

Desired raw material ash content - up to 15 ... 16%

Production Process





How it works

1. Crushing (if needed)

2. Wet Milling 3. Storage or Transport





Why it is Better?

Burnout level for Fine particles is 98% and higher Higher efficiency of coal usage Low cost for heat energy production

Internal moisture of most of coals is already 15...30%, accordingly, the amount of added moisture does not exceed 25%. According to physics addition of such amount water and its evaporation in the boiler furnace is more efficient than pre-drying of raw material and further milling.

Presence of water slightly reduces average flame temperature – lower NOx emissions

CWS is a coal (carbon) in a liquid form• Transported locally by a pump – no dirtiness• Clean infrastructure• No risks for explosion

99% of particles are LESS than 150mkm

Advantages

Main Advantages of CWS Technology:

• Fuel costs reduction for coal-fired, oil-fired boiler of small and medium power for 30 ... 50%

• Complete combustion of coal (carbon) in the form of CWS, according to compared with layer combustion on coal boilers

• Significant Reduction of NOx emissions, possibility of compensation of SOx emissions

• Explosion proof

• The possibility of recycling sludge, waste

• Partical size (dependend on coal) 30...150 mm

Energy consumption:• Installed capacity 44 kW,

• Running consumption 10 kWh per t

Dimensions:• without conveyor, (L × B × H)

2280×1900×1750mm

• Weight 1600 kg

• Low costs CWS Production• Compact• Simple for operation• No foundations required





CWS Intermediate Storage

Local storage tank with mixer, 1…4m3

Pump

Air compressor of CWS spraying

Control Shelf

Metal frame

Fitted into a standard container





CWS Combustion

• CWS Spraying nozzle• Swirl prechamber for CWS combustion





Low Emissions

• Burning coal in the form of CWS reduces emissions of nitrogen dioxide (Nox) on 35…40% comparing to classcoal combustion

• Mechanical unburnout level of coal in a form of CWS does not exceed 1..2% while comparing to standard 10…30% for small-to-medium size boilers

• Environmentally friendly fuel at all stages of production and use,

• Accidental spills do not harm the environment

• Ashes from the combustion of CWS contains not more than 3% of less




Investment Efficiency CWS vs Other fuels

Economical Figures





Industries

Heat and steam for industries

Reduced fuel costs by 20 ... 40% on steam production for technological needs chemical redustions of sugar refineries, textile and other industries.

Steam boilers are the most adapted for the CWS reconstruction.

Recycling of pyro carbon / carbon

CWS from carbon after pyrolysis of rubber tires and other raw materials, is an additional fuel for liquid fuel boilers.

For public utility companies

Reduced fuel costs by 30 ... 60% compared with masut and by 20 ... 40% compared with classical combustion of coal. Reduction of NOx emissions by 20 ... 30%. The minimum cost of CWS reconstruction on coal-fired boilers

For asphalt plants, kilnes, etc

CWS is used as a primary or additional fuel heating asphalt furnaces, drying kilns for different industries, etc
