Abstract

The operating thermal power plants emit greenhouse gases which cause an undesirable greenhouse effect. One of the ways to reduce emissions of such gases is to create oxyfuel-energy units and use of carbon dioxide as diluent. However, for effective combustion efficient CO₂/O₂ mixing is required which is possible only by employing external gas mixer.

This paper presents the results of the gas mixer study design. Based on the results of numerical modeling of the flow of combustion components in the gas mixer it is established that the location of deflectors and diffusors plays important role in mixing of components in the mixing chamber.
