Abstract


The research object is the convective heating surface of water boilers. 

The purpose of the work is heat engineering design calculation of the options for upgrading the convective heating surface of the KVGM-100 boilers. 

As a result of the calculations performed according to the proposed methodology, it is revealed that replacing smooth pipes with an outer diameter of 28 mm in the convective bundle of the KVGM-100 boiler unit with finned tubes with an outer diameter of 38 mm can increase the density of the transmitted heat flux by 30 times. Such heat transfer efficiency in a convective beam will increase the efficiency of the boiler as a whole and, consequently, reduce the boiler fuel consumption.
