CyClean
ACHIEVE MACT LEVELS OF MERCURY EMISSIONS AT NO COST

REFINED COAL TAX CREDIT
The American Jobs Creation Act of 2004, Section 45 contains provisions to incentivize the production of Refined Coal that will reduce emissions of several pollutants to qualify for a tax credit of $6.00/ton. ADA-ES CyClean has been demonstrated full scale at several power plants and has shown that it can reduce NOx and mercury emissions to qualify for this tax credit.
ADA-ES and NexGen Resources have created a joint venture to produce and qualify
CyClean for the Section 45 Tax Credit.  We will work with your plant to test CyClean and build a qualifying facility that will be simple and cost effective.   

CYCLEAN PRODUCT BENEFITS

Achieve MACT levels of Mercury Emissions
Simple storage and additive system
Improved operations
Increased boiler turn down range
Increased fuel flexibility
Safer operations, less slag tap freezing
Potential tax credit qualification as Refined Coal


SIMPLE SYSTEM

ADA CyClean is a cost effective coal additive that is added to the coal just prior to the crusher, enabling it to be evenly distributed in the coal supply before combustion.  CyClean comes in a granular form that is added to a coal supply belt with a simple storage and conveying system. It will not harm coal crushers or coal conveying belts. (See picture)

CyClean Operational Experience

More than 10 full-scale tests

Completed two permanent installations Dec 2009

Operating 24/7 since July 2010

Treating 98% of coal burned in 4 boilers

Continued CyClean technology optimization

  • Science & engineering expert teams

  • PRB COAL AND CYCLONE BOILERS
    Most of the cyclone fired boilers have switched from their design fuel to PRB coal. This has been done to reduce SO2 emissions, lower NOx levels and reduce fuel costs. These boilers were designed for high sulfur Midwestern bituminous coal and using PRB in them is not without some issues.

    COMMON PROBLEMS EXPERIENCED BY CYCLONE OPERATORS THAT CAN BE ALLEVIATED WITH CYCLEAN
    • Slag layer in cyclone barrel is too thin for good combustion
    • “Eyebrows” of slag build up in cyclone
    • Slag freezes in the “monkey hole” and won’t tap easily
    • More coal burns in suspension and increases flyash loading
    • Incomplete combustion raises LOI in flyash
    • Less bottom ash produced
    • Must blend in bituminous “kicker” coal to unclog slag tap
    • Only one or two PRB coals are “acceptable” fuels
    • Unit cannot operate at lower load levels without slag tap freeze-up

    CAUSE OF THESE PROBLEMS
    PRB coals have a much steeper temperature vs viscosity curve than bituminous coals. This means that the temperature range for the slag to stay at the proper viscosity is much smaller than with the design fuel. Small changes in temperature can cause the slag to be too thin or too thick.
