The article presents the results of processing experimental data obtained from the results of tests of a condensing hot water boiler developed by employees of the Belarusian State Technical University. V.G. Shukhov. The scope of the boiler is autonomous heating systems. The use of a boiler in such systems makes it possible to achieve significant savings in fuel spent on generating a unit of heat. The dependences of the parameters of energy carriers, as well as the heat transfer coefficients on the performance of the boiler, are given. As a result, the values of indicators characterizing the intensity of heat transfer in the elements of the high-temperature part of the condensing hot water boiler are within the same limits as the values of similar indicators of traditional hot water boilers. However, the possibility of maintaining higher temperatures of gases at the outlet of the high-temperature part compared to the temperatures of the exhaust gases of traditional boilers can significantly increase its compactness compared to analogues. The test results showed the compliance of the parameters of the heat carriers produced in the condensing hot water boiler with the requirements of the standards. All of the above gives reason to believe that the use of the proposed boiler as a heat generator in autonomous heat supply systems is very promising.
