TRIO-BOCO; It is a liquid sludge coagulant that prevents the formation of deposits and sludge deposits in the metal parts of both medium and low pressure boilers. By using TRIO-BOCO, sludge is dispersed in small particles and is removed from the boiler with the help of blowdown in the boiler and overheating and pipe splits in the boiler pipes are prevented depending on the deposit. TRIO-BOCO is also easily used when fuel leakage from the feed water into the boiler is observed. By coagulating the fuel droplets, the suspension solids are lowered to the bottom of the boiler and blown out of the boiler. If the fuel leakage is excessive and continuous, the cause of the leakage must be investigated, the leakage must be stopped and off-line cleaning must be carried out.
