Abstract
At start up, about 15 percent of a full working load of feed water is supplied to the evaporator directly while an additional flow of feed water at least 30 percent larger than the flow to the evaporator is supplied to the superheater by the additional feed line under full working pressure. During this time, the flow of working medium is bypassed back into the degasser while the burner is supplied with about 15 percent of full fuel load and 25 percent of full combustion air load. Once steam becomes generated in the evaporator, the pressure at the superheater is rapidly reduced to permit the starting up operation to proceed at an increasing pace.
