THE THIRD GENERATION OF EXHAUST GAS ECONOMIZER AND ITS OUTER FOULING

The progress of the exhaust gas economizer (EGE) can be classified into three historical groups, that is, units of the 1st, 2nd, and 3rd generations. The main technical feature of each generation can be regarded as the single-stage pressure system, the multi-pressure system, and the diesel-steam combined system, respectively. The 3rd generation units, the most advanced EGE plants, have remarkably improved the recovery of waste heat from the main engine. They are very vulnerable to outer fouling, however, and apt to be attacked by the severe fault called the soot fire. The possibility of the soot fire is examined by considering the relation between the soot burning and the water circulation, and the importance of countermeasures against the outer fouling and soot fire is made clear. On the basis of the above considerations, concrete countermeasures are proposed.
