The Improvement of the Effectiveness of Using Natural Gas in Hot-Water Boilers by Means of Condensing Economizers

摘要

The paper describes the results of the study of the mathematical model of a condensing economizer (CE) interacting with the technological parameter of the particular district heating station. This model has been developed by the authors. It is shown that the CE, due to condensation of water vapor and augmentation of convective heat exchange between products of natural gas combustion, makes it possible to save up to 8% of fuel.
