Abstract

A method for operating a heating boiler and variant embodiments thereof are proposed. A working fluid is heated in the heating boiler consisting of at least two chambers by the heat of at least one heat carrier, and, by means of at least one of the heat exchangers in the heating boiler, a change in the temperature of the heat carrier in relation to the working fluid in the chambers is realized by supplying a more greatly heated heat carrier to the chambers containing a more greatly heated working fluid and, correspondingly, supplying a less greatly heated heat carrier to the chambers containing a less greatly heated working fluid, and, after heating, the working fluid is conducted out of the chamber via at least one channel or valve for use. The technical result is an increase in the efficiency of the heat recovering.

Dependent claims

A method for operation of a boiler, comprising:

heating a working body in the boiler, the boiler being made of at least two chambers, the heating being performed by at least one heating medium, the boiler comprising at least one heat exchanger;
when a first one of the at least two chambers contains the working body and a second one of the at least two chambers contains the working body, and the working body contained in the first one of the at least two chambers has a higher temperature than the working body contained in the second one of the at least two chambers, heating the working body in each of the first one and the second one of the at least two chambers by using the at least one heat exchanger to add a heating medium at a first temperature to the first one of the at least two chambers, and respectively add a heating medium at a second temperature to the second one of the at least two chambers, the second temperature being lower than the first temperature;
and
after the heating of the working body in each of the first one and the second one of the at least two chambers, removing the working body from each of the first one and the second one of the at least two chambers for further utilization through at least one channel or valve.
