The paper is devoted to the issue of increasing the maneuverability and efficiency of modern cogeneration systems based on gas turbine power plants. Promising solutions for increasing the maneuverability of GTU-CHPP by using heat accumulators and the formation of a preheating circuit of the network water are considered. It is shown that in the non-heating period, it is possible to increase both the thermal efficiency and the generated electric power by installing a heat exchanger in front of the compressor. The calculation results show that this provides an increase of 0.4% in the net electrical efficiency by and an increase 3.3% in the annual electricity generation.

“…The process of TPP operation involves emission of combustion products into environment, which mainly consist of gases that provoke the greenhouse effect. In addition to using plants to capture harmful emissions, there is a potential to minimize them through the use of oxyfuel technologies [1,2] . Unlike conventional plants, oxyfuel power units (OFPUs) do not pollute the atmosphere with emissions, thanks to the closed-loop Brayton cycle, the use of oxyfuel for a combustion and the prevention of carbon dioxide by removing from the cycle.…”

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.
