CONTINUOUS STEAM GENERATOR WITH BALANCE CHAMBER Russian patent published in 2015 - IPC F22B21/02 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering and may be used in heat recovery steam generators comprising a balance chamber. The substance of the invention consists in the fact that an evaporation system for fluid evaporation with primary and secondary evaporators comprises at least in each evaporator one inlet, multiple outlet pipes; at the same time multiple outlet pipes of the primary evaporator are connected with at least one inlet pipe of the secondary evaporator, and also lower and upper headers, multiple lower and upper pipes, an intermediate chamber that communicates through fluid medium with upper ends of lower pipes and lower ends of upper pipes, at the same time primary and secondary evaporators are located in a channel with a heated flow of fluid medium, at the same time the primary medium is located further away from the secondary evaporator relative to the heated flow of the fluid medium.

EFFECT: such design makes it possible to produce a more even temperature of superheated steam in an inlet hole of evaporators, which will reduce difference of temperature stresses during start and under variation of linear loads, increasing service life of tube connections to an evaporator header.
