Dry Wallnut Shell Turbocharger Cleaner

DESCRIPTION :

RXSOL Turbo Cleaner Dry Walnut Shell is natural organic materials with controlled particle size used for cleaning blades of gas side of exhaust-gas turbochargers in modern diesel engines. The specific structure of RXSOL Turbo Cleaner Dry Walnut Shell is such that when injected by means of compressed air upstream in the gas side of the turbine it causes a slight abrasive action which maintains the turbine is always clean.

Once injected in the turbine RXSOL Turbo Cleaner Dry Walnut Shell burn and disappear into the atmosphere through the stack without causing any detrimental chemical reaction. Although that method is efficient it presents a number of drawbacks such as reduction of the rpm of the engine during the entire cleaning process, which causes a loss of speed. Furthermore there is always the risk of forming corrosive acids in presence of sulfurous residualsin the discharge duct.

APPLICATION :

Instead of water, dry solid bodies in the form of granules like RXSOL Turbo Cleaner Dry Walnut Shell is used for cleaning. A certain quantity of them, depending on the turbocharger size, is blown by compressed air into the exhaust gas lines before the gas inlet casing On account of their hardness and composition (natural solid granules, size 1.3-1.7 mm.) RXSOL Turbo Cleaner Dry Walnut Shell have an excellent mechanical cleaning eff ect (soft blast). As a rule, a turbine should be cleaned every 24 to 48 hours of operation.

"WITH RXSOL TURBO CLEANER DRY WALNUT SHELL IT IS NOT NECESSARY TO REDUCE THE SPEED OF THE ENGINE."
"THERE IS NO RISK OF CORROTION DUE TO ACID FORMATION."

When used regularly, RXSOL Turbo Cleaner Dry Walnut Shell  increase significantly the time between maintenance services. Obviously, maintaining the turbine in a perfectly clean condition gives trouble-free operation and improves efficiency.

TECHNICAL SPECIFICATION

DOSE

Follow the instructions of the manufacturer of blower turbines. As an indication, an average dosage for a 8,000 to 10,000 HP engine would be 0.6-0.8 dm3 of
RXSOL Turbo Cleaner Dry Walnut Shell injected daily in the blower turbine.

P R I N C I P L E

RXSOL Turbo Cleaner Dry Walnut Shell  is blown by compressed air into the exhaust pipes before the turbocharger. This method of cleaning should be employed every 24 -48 hours of full-load operation. The interval between cleaning operations depends on the degree of contamination and on the increase in exhaust gas temperature after the turbine. Cleaning must be repeated if the gas temperature after the turbine on full load rises to 20°C (20 K) above the mean temperature. For a turbocharger with several gas inlets, the inlets should be cleaned one after the other. On  engines with several turbochargers, these should be cleaned one after the other. The gas inlet temperature before the turbine must not exceed 580-590°C (853-863 K) in order to prevent severe burning of the RXSOL Turbo Cleaner Dry Walnut Shell  before the turbine. Since it is not possible to remove thick coatings with relatively small quantities of RXSOL Turbo Cleaner Dry Walnut Shell , this method must be used more frequently. Injection of the RXSOL Turbo Cleaner Dry Walnut Shell  into the turbine is best performed at high turbocharger speed, to ensure effi cient mechanical cleaning.

INSTALLATIONS OF RXSOL TURBO DRY WALL NUT SHELL CLEANING SYSTEM

• Before each gas inlet, an adequately dimensioned pipe fl ange has to be selected and installed in the exhaust gas line (weldedm or cast eye).
• Manufacture of containers (same number as gas inlets)
• Mount the fi ttings such as valves and the like.
• The container has to be mounted with the strap provided for this purpose at an easily accessible location, the cock or gate valve being at least 300 mm above the corresponding pipe fl ange in the exhaust gas line. Maximum distance between cock or gate valve and pipe fl ange/exhaust gas line: 1 m.
• Arrange the compressed-air pipe to the container.

CLEANING PROCEDURES

For engine with several turbochargers, clean one after the other as follows:

1. Close the safety valve, tighten the valve cap. Open the cock/gate valve.
2. Open the compressed-air stop valve. Possible deposits and/or condensate in the connecting pipe are now blown out. Close the compressed-air stop valve after about 3 minutes.
3. Close the cock/gate valve.
4. Open the safety valve. The exhaust gas pressure in the container is thus relieved. Close the safety valve.
5. Remove the valve cap. Fill the container with the quantity of ASTEROIDS product specified in the table of next page.
6. Check on whether the safety valve is closed. If at all required, reduce the engine output so that the gas temperature before the turbine is < 590°C (863K).
7. Open the cock/gate valve.
8. Open the compressed-air stop valve. The previously filled-in ASTEROIDS are now blown in. Close the compressed-air stop valve after 1 to 1,5 minutes.
9. Close the cock/gate valve.
10. Open the safety valve. The exhaust gas pressure in the container is thus relieved. Close the safety valve.
11. This procedure (item 1 to 10) has to be repeated for any further turbocharger.
12. Cleaning should then be repeated at periodical intervals of every 24 to 50 hours of operation.
     

WARNING

It may occur that, during dry cleaning of the turbine, a small part of blown-in Asteroids escapes through the chimney in singed condition.

GENERAL REGULATION

• The gas inlet temperature before the turbine must be not exceed 580 - 590 °C (853 - 863 K)
• The boost pressure should be over 0,5 bar
• The drain openings in the gas outlet casing must remain closed during dry cleaning
• The mean particle size of the cleaning granulate must be between 1.3 and 1.7 mm

RXSOL Turbo Cleaner Dry Walnut Shell  is produced from hard shells of fruit stones that have been stabilized by drying and degreasing. Ligneous residues and foreign matter such as mineral or metallic particles are eliminated. RXSOL Turbo Cleaner Dry Walnut Shell  is the result of many years of practical experience in blending the raw material to achieve a highly homogeneous and efficient product. No chemicals are used in our production process. The raw materials are only treated mechanically. Hence the use of RXSOL Turbo Cleaner Dry Walnut Shell  is perfectly safe and harmless. RXSOL Turbo Cleaner Dry Walnut Shell  is now produced with improved particle size tolerance of Ø 1,3 to Ø 1,7 mm.
