ABSTRACT:
A continuous-flow steam generator has a combustion chamber with a number of burners for fossil fuel. A gas-tight containing wall is formed from approximately vertical evaporator tubes, through which a medium passes from the bottom upwards. A start-up process is maximized with regard to the reduction in start-up losses. The evaporator throughput is set in proportion to the firing heat capacity in the combustion chamber. A control device has a control module for setting the quantity of medium supplied to the evaporator per unit time, in dependence on the fuel quantity supplied to the burner or each burner per unit time.
