Determination of the expedient volume of using the technology of thermochemical recuperation for gas turbine plants of Ukrainian gas-pumping stations
Journal Title: Проблеми загальної енергетики - Year 2018, Vol 0, Issue 4
Abstract
We performed thermodynamic and technical-and-economic calculations of the scheme of thermochemical recuperation (based on natural gas reforming with combustion products) for 12 models of gas turbine plants of Ukrainian gas-pumping stations. It was established that, for most models, the pay-back period of investment to the TCR scheme does not exceed several months. We recommend to introduce TCR scheme at 40 gas turbine plants with a total power of 505 MW, and the cost of fuel that can be saved constitutes 420 mln. UAH per year.

Security aspects of the balance of carbonaceous fuels under conditions of establishing the new fuel supply schemes in Ukraine
We give an estimate of the state of energy security at the supply of carbonaceous on the basis of representation of the fuel supply system in a three-fuel economic-and-mathematical model of the production type. We presen...
Determination of the optimal conditions of the work of a hollow scrubber for gas cleaning from solid particles
Based on the analysis of the physical picture of transfer phenomena in a three-phase flow, we have composed a complete list of quantities that describe the behavior of a polydisperse three-phase mixture in a hollow scrub...
Enhancement of the efficiency of operation of heat and power plants witch using low-cost technologies
