REDUCTIONS IN CHARGES FOR ATMOSPHERE POLLUTING
Providing that “SADPAL” product is used regularly, the following reductions in
payments are possible:
- for solid grates up to 55%;
- for mechanical grates up to 25%;
APPLICATION OF “SADPAL” ELIMINATES
1. polluting of atmosphere with soot (black smoke);
2. higher fractions of aromatic polycyclic aromatic hydrocarbons /PAH/,
3. emission of carbon monoxide into atmosphere;
4. requirement to perform mechanical removal of soot sediments from
5. down-time related to mechanical removal of soot sediments from
6. soot combustion in the chimney canal.
IT ALSO CAUSES REDUCTION IN:
1. emission in sulphur dioxide into the atmosphere by approximately 12 –
20% due to coal savings;
2. coal consumption, ranging from 12 to 20% depending on its caloric
3. the content of SO2 and NOx in combustion fumes, ranging from 10 to
4. corrosion speed of steel construction elements of grate furnaces in
boilers and combustion gases disposal installations;
5. increases the efficiency of cyclones, multicyclones and electrofilters.
UTILITARIAN PROPERTIES AND APPLICATION RANGE OF
“SADPAL” is a green powder – a mixture of inorganic salts, which are subject
to decomposition into substances with catalytic properties under temperatures
in excess of 65şC.
This product is used to combust soot and organic substances to their final
products – carbon dioxide and water.
Application of “SADPAL” does not pose threat to grate furnaces and
combustion gases disposal installations; quite on the contrary – it extends
their life cycle (expert opinion of the Institute of Material Science, School of
Mining and Metallurgy in Cracow from the 20th of February 1991).
“SADPAL” improves life cycles for cyclones, multicyclones and electrofilters.
It is not a flammable or toxic product (evaluation issued by the National
Institute of Hygiene in Warsaw, number 24/B-23/91), is not explosive and does not pose threat related to its improper application or over-dosage. Since 1991 it has been successfully applied in hundreds of plants and thousands of individual customers.
SADPAL” eliminates soot and fly-ash through their combustion.
Uncombusted hydrocarbons, including benzopirane, are combusted together with soot deposits. Carbon monoxide is combusted to carbon dioxide.
Reduction in the level of SO2 by approximately 10-20% and NOx by
approximately 5 -10% in the combustion gases is the direct result of their being bound by the chemical components of “SADPAL”.
“SADPAL” demonstrates activity in the following groups:
- cleaning of the boiler surfaces;
- enhancement of the combustion processes – decrease in the amount
of solid molecules included in the combustion gases and decrease in
the carbon dioxide concentration;
- reduction in the SO2 and NOx concentrations;
- reduction in the high and low temperature corrosion;
- reduction in the total dust content;
Regular application of “SADPAL” with the application ratio of 1 – 2 kilograms per a tone of coal eliminates any deposits in the furnace and heating pipes, maintaining them in working order during the heating season.
Thanks to that, the down-time designated for furnace cleaning is short and only involves the removal of ashes collected in the back part of the furnace.
As a direct result of “SADPAL” application, the ash deposits change their structure, become loose and fall off the walls, because the soot – which was keeping them together – was burned out. Newly sedimented ash deposits are burned out immediately – the walls of the furnace remain clean all the time.
“SADPAL” does not cause additional mineral sedimentation on heating
elements (heating screens) – it does not contain any dolomite in its structure.
Due to its numerous and above mentioned advantages, it is widely applied during exploitation of furnaces heated with coal, fine coal, wood, peat, brown coal, both in medium and large heat generation plants. It significantly improves the boiler efficiency, at the same time keeping its walls clean. Every millimetre of sediment (slag, soot sediment) of the boiler’s wall increases fuel consumption by 10%.
The first application of “SADPAL” in the given boiler should feature such an amount of the product, which allows for the combustion gases, emitted from the furnace, to be of white colour (for example, for the boiler with total area of 25m2, approximately 6 kilograms of the product should be introduced). Then, “SADPAL” is introduced into the furnace mixed with the fuel at the ratio of 1-2 kilograms of the product per 1 tonne of coal. In large heat generating plants the product might be introduced into the boiler with the use of a perpetual
screw, driven by the direct current (DC) engine (with varying speed), placed over the coal (fuel) feeding mechanism. The product is introduced into smaller boilers by hand dusting the powder onto the proper amount of coal (in the wheel-barrow, in a heap with the proper ratio of 1-2 kilograms of coal per 1 tonne of fuel).
The combustion gases emitted from the chimney ducts ought to be of whitecolour, when “SADPAL” is applied.
