Literature - Technology
Combustion-related problems in boilers include slagging, fouling, high temperature corrosion and cold-end corrosion of heat transfer surfaces and other boiler components. Deposition is related to the presence of impurities in the fuels being burned while combined with combustion practices. High temperature deposition will occur when molten ash derived from fuel impurities, comes into contact with the metal surfaces of the boiler and solidifies. When this “slag” contacts a metal surface, additional ash particles become trapped within the sticky molten mass, this results in fouling and uncontrolled heavy slagging. Once deposits have formed, corrosion can result beneath. Soot blowing may not be able to remove these tenacious deposits. Continuous build up, will result in lost efficiency and reduced throughput of the boiler. High temperature corrosion causes metal loss and eventual tube failure.
SOOT CLEANER LIQUID combines with various ash constituents to raise their melting points and weaken their deposit structure. This permits the ash to pass through the boiler as a solid and increases friability of any deposits, which do form, making deposit removal easier by means of soot blowing or off-line cleaning. Sulfur trioxide (SO 3 ) is formed from the combustion of sulfur contained in fuels. It combines with water vapor in the flue gas to form Sulfuric Acid. The acid corrodes metal surfaces that are below the acid dew point. This condition is typically referred to as low temperature or cold-end corrosion. In addition, the corrosion products can block gas passages between tubes.
SOOT CLEANER LIQUID reduces the catalytic conversion of Sulfur dioxide (SO 2 ) in the flue gas to Sulfur trioxide (SO 3 ). Preventing the formation of SO 3 in the flue gas can also result in lower stack opacity. Also, SOOT CLEANER LIQUID directly inhibits acid corrosion by neutralizing Sulfur trioxide (SO 3 ) and coating the tube surfaces.

Application and Use
A. Dosing Procedure
The quantity of SOOT CLEANER LIQUID to be used can depend on many factors such as the type of problem and its severity; we must also take into consideration the design and operating characteristics of the boiler. The suggested quantity of SOOT CLEANER LIQUID is 1 litre per 4-6 cubic meters of fuel. Note that the above quantity may be altered, depending on the type of system to be treated, based on particular variations in the quality of the fuel and/or the manufacturer’s technical specifications.
B. Cleaning Procedure
SOOT CLEANER LIQUID is applicable to many systems such as diesel exhaust gas economizers, fire tube boilers, main boilers, etc. In the case of diesel exhaust systems, the product is applied upstream, of the area being treated into the exhaust gas system. In the case of boilers, the product is applied from a suitable port point of the system, preferably with an injector, making sure that the liquid is spread right through towards the backside of the combustion chamber.
