摘要： A method for operating a steam generator comprising a combustion chamber having a plurality of evaporator heating surfaces which are connected in parallel on the flow medium side is provided. An object is to provide a steam generator which has a particularly long service life and which is particularly reliable. For this purpose, a flow medium is introduced into an inlet of a first evaporator heating surface at a temperature which is lower than the temperature of the flow medium introduced into the inlet of a second evaporator heating surface.

摘要： THE FIN SURFACES IN ANY PLANE ARE SUBDIVIDED INTO CONCENTRIC RINGS OR CYLINDERS WHOSE INNER PERIPHERIES ARE EACH ATTACHED TO THE OUTER EXPOSED SURFACES OF A CIRCULAR ARRAY OF PIPES, SO THAT THE CONCENTRIC ARRAYS OF PIPES ARE MECHANICALLY SEPARATED.
A COMPACT CONFIGURATION FOR HEATING OF A LIQUID, BOILING OF A LIQUID AND SUPERHEATING THE VAPOR OF A LIQUID. A CYLINDRICAL ARRANGEMENT IS PROVIDED IN WHICH PRODUCTS OF COMBUSTION ARE INTRODUCED FROM THE PERIPHERY OF THE CONFIGURATION TOWARDS THE AXIS THEREOF IN A RADIALLY INWARD DIRECTION WHILE THE FLUID TO BE HEATED FOLLOWS A LABYRINTHINE PATH FROM THE AXIAL REGION TOWARDS THE PERIPHERAL REGION. THE LABYRINTHINE PATH CONSISTS PREDOMINANTLY OF LENGTHS OF PIPE OF SMALL DIAMETER ARRANGED AXIALLY IN A CYLINDRICAL ARRAY IN UP TO THREE COAXIAL ZONES. IN THE INNERMOST ZONE THE FLUID IS LIQUID. IN THE OUTERMOST ZONE THE FLUID IS IN THE VAPOR STATE AND THE INTERMEDIATE ZONE CONSTITUTES THE BOILER. HEAT TRANSFER SURFACES ARE DIFFERENT IN EACH ZONE. NOTHING IS ADDED TO THE PIPES IN THE VAPOR ZONE. THE PIPES IN THE BOILER ARE MECHANICALLY CONNECTED TOGETHER BY FLAT PLATE FINS OR OTHER EXTENDED SURFACES EXTENDING IN THE RADIAL DIRECTION SO AS TO PROVIDE MINIMUM INTERFERENCE WITH FLOW OF THE PRODUCTS OF COMBUSTION. SIMILAR EXTENDED SURFACES ARE USED IN THE INNERMOST ZONE, EXCEPT THAT IN THIS ZONE

摘要： The forced circulation steam generator is provided with a means for measuring the difference in pressure between two levels in the water separator in order to measure the water level in the separator. The water feed rate to the evaporator is controlled in dependence on the measured pressure difference in the separator when the separator contains water and in dependence on another variable, such as the temperature at the outlet of a superheater, when the separator is dry.

摘要： A compact combustor-boiler construction is described that during operation will emit substantially no nitrogen oxides, while burning a fuel/air mixture essentially to completion. Nested cooled porous plug burners with a common fuel/air supply chamber are flanked by inner and outer burned gas cooler units with the coolant flow paths through the burners being connected in series with a flow path through the outer and inner cooler units in sequence whereby the coolant (working fluid) is sequentially exposed to liquid heating, nucleate boiling, film boiling and, preferably, super-heating.
