In our process we receive Bunker 'C' from our heating plant at about 150 degs F. It is further heated through heat exchangers to 275 degs F. before it is atomised in our burner guns in the induration furnace. Normal shutdown of this system would require light fuel to be added to the lines to flush out the residual bunker. This year during the mtce shut in June we are looking at a complete shutdown for 24 to 36 hrs without flushing the lines with light fuel. As the fuel cools in these lines, will they become plugged with cold bunker. What other issues can we expect with startup?
