The article considers the state and prospects of bioenergetics development in the context of rationalization of the use of available natural resource potential of Ukraine. It is determined that one of the most perspective renewable energy sources is biomass, the main component of which is by-product of plant growing. It is noted that the use of by-products of crop production for receiving heat energy is a rational way to utilize their surpluses that are not used for other purposes of agriculture. The existing resource potential of this agricultural biomass and source of its obtainment were characterized. An estimation of the potential of this type of biomass up to 2025, which can be used for thermal power engineering was made. It was noted that the effective use of biomass potential of agricultural enterprises is possible in case of creation of the appropriate mechanism, a set of management decisions aimed at solving the energy issue. The structure of the formation of the economic model of the influence of factors on the state of the use of by-products of crop production in thermal power engineering was proposed.

For many years, the Department of Power Engineering and Turbomachinery of the Silesian University of Technology has been using a small-capacity (about 500 kWe) steam-gas power plant. Based on many years of experience in operation of this power plant utilizing the Velox-type gas-steam system, an idea arose to modify this type of thermal power cycle to create a combined heat and power (CHP) plant of small capacity, dedicated for distributed heat and power production or production process steam with high temperature. Previous thermodynamic and economic analysis of that type of low-power CHP plant confirmed many advantages of using this type of solution in low-power engineering. The new idea is to add a throttle valve between the economizer and the evaporator for the reference cycle of the gas-steam Velox-type CHP plant. It was further assumed that water would partially be vaporized on the valve. This paper presents a thermodynamic and economic analysis of this type of a system with an added throttle valve. Downstream the valve, the evaporated water fraction is fed directly into the steam superheater. It is determined how such a retrofit affects the system thermodynamic and economic characteristics. The system is modelled in the EBSILON® Professional 14 software.
