How to use Coal Catalyst CC-88

CC-88 is a dry powdered combustion catalyst. CC-88 effectively, economically and safely reduces: fuel use, fireside deposits, fly ash, sulfur and nitrogen oxides emissions. It can provide these benefits to a wide variety of boilers of almost every design and size. This would include boilers fired with raw coal, washed coal, pulverized coal, heavy oil, refuse, wood fueled stoker fired or Fluidized bed design.

Coal Catalyst CC-88 is usually mechanically fed or injected into the boiler to create a catalyst bed in the bottom of the combustion chamber. For consistent results, CC-88 catalyst is added continuously into the burner or combustion zone with the fuel or alongside the fuel through separate piping. CC-88 application methods vary with the method used to fuel the furnace, the size and configuration of the boiler system components and the type or existence of flue gas cleaning (pollution control) equipment.

When the coal is burned in a stationary bed, CC-88 is usually dosed onto the bed by blowing it into the combustion chamber using piping. However when the boiler is small, CC-88 may be dosed onto the bed manually by the boiler operator.

When the coal is fueled as bricks or briquettes, it is best to introduce CC-88 onto the coal surface during the compression process while manufacturing the briquettes.

Feed rates of CC-88 vary depending on the type of coal, the dynamics of the furnace, and what end results are needed. If the primary goal is to reduce slagging, a feed rate from 1kg to 2kg per tonne of coal is normal.

CC-88 Applications vary with goals and objectives

Objective - To save fuel: CC-88 works as a catalyst to accelerate the oxidation-reaction of carbon to produce more heat per unit time, in other words, less fuel is used for the same heat production.

Objective - To reduce cold end soot and boiler fouling: CC-88 works as an oxidizing agent. CC-88 oxidizes carbon during combustion at temperatures lower that normal ignition temperatures; this speeds combustion and uses more carbon and reduces soot deposits in the system.

Objective - To maintaining optimal boiler function: Coal Catalyst acts as a slag modifier to alter slag deposits and provide cleaner heat-transfer surfaces reducing boiler cleaning costs. CC-88 will extend operating cycles of boilers, and enable operators to operate their boilers with new and improved operating capacity, even using high ash coal that typically tends to plug air passages and create unscheduled shutdowns.

Objective - Pollution control: CC -88 sequesters sulfur, reducing the quantity of sulfur dioxide in the flue gas. CC-88 also reduces the carbon carry-over that normally provides seeding of fly-ash particles, thereby decreasing particulate emissions and wasted carbon carry over.
