Product Description
DESCRIPTION ROCHEMITE is an inorganic compound in powder form for application in coal or oil fired boilers, exhaust gas boilers, incinerators and process furnaces. ROCHEMITE prevents slag build-up by means of a chemical reaction.  It also removes existing combustion deposits and slag from the refractory coating and metal fireside surfaces of boiler tubes, superheaters, exhaust gas uptakes and exhaust gas boilers. 
 
SPECIFICATIONS Colour   : Grey or Brown Apparent Density  : 0.9 Flash point  : None Chlorides   : None Shelf-life   : Indefinite 
 
APPLICATION ROCHEMITE is injected into the boiler furnace first or second draft depending on boiler type and construction.  A minimum gas temperature of only 300°C is required for effective cleaning as ROCHEMITE does not burn but forms a dense vapour that reaches into all parts of the boiler reacting with the fireside deposits and reducing these to a soft powder.  Manual cleaning and soot blowing is reduced to a minimum or can even be eliminated completely.  Reaction with Rochemite forms a protective film on clean surfaces thus preventing attack by aggressive acids in both high an low temperature zones. 
 
CORROSION PROTECTION Combustion deposits in untreated boilers contain Sulphur compounds resulting in a pH of 1 to 3.  Although this means that the slag is corrosive, nothing is known about the total acid content. However both pH and acid content influence each other. For example, if the pH increases by one point the acid content correspondingly decreases by 90%. ROCHEMITE increases the pH and consequently reduces the acid content in such a way that free sulphuric acid (H2SO4) is kept to a minimum; Thus the presence of Ferreous Sulphate (FeSO4) is eliminated.  ROCHEMITE prevents Sulphur corrosion when applied regularly. 
 
DOSAGE A. Injection – oil / Coal Fired boilers The dosage depends on the Boilers capacity, type of fuel used and Sulphur content thereof. 1. The required quantity of ROCHEMITE is blown, by means of an injector, into the furnace, if possible into the highest temperature zone of the flame. 2. Inject ROCHEMITE after soot blowing has been completed. Inject in the shortest possible time. 3. If possible reduce the draft in the boiler for 2-4 minutes during and after injection in order to allow the ROCHEMITE vapour to spread throughout the boiler. 4. The speed of the chemical reaction is greater at higher temperatures. 5. The part of the boiler to be treated in particular should not be at a distance greater than 10-12 meter from the injection point. 
 
B. Injection – Diesel Engines uptakes/ Exhaust Gas Boilers  To prevent slag build-up in exhaust gas uptakes and boilers, ROCHEMITE is applied as follows: 1. Fit injector in exhaust gas line just prior to or just after the turbo charger. 2. Inject ROCHEMITE with compressed air for a few seconds. 3. Inject ROCHEMITE only at full load of engine as a temperature of minimum 300°C is required to vaporize ROCHEMITE. 4. Dosage and frequency depend on fuel consumption, fouling problem, etc and may vary from 2 to 4 kg every day to every three days.
