Abstract
Renewable energy has become increasingly important in the last decade due to the limited reserves of fossil fuels and environmental issues related to CO2 emissions. The paper investigates the joint production possibility of electricity and heat in the Tomsk district Stepanovka, using modern trigeneration plant. The analysis was performed based on a comparison of the two alternatives for the area: the use of a diesel power plant (DPP) or gas-piston units (GPU) on biofuel. Technical and economic indicators for two different systems were calculated to evaluate the projects effectiveness.
Highlights
Reduction of natural hydrocarbon resources, rise in price of oil and gas production systems, electric and heat energy tariffs increase, environment pollution by emission of carbon dioxide and global warming [1,2] enhance the interest in the use of renewable energy sources
Energy resources consumption reduction and their efficient allocation can be provided by more efficient power plant with a combined production of heat / electricity / cold. [1]
The heat excess generated in the motor can be used for heat and cold generation for consumer needs
Summary
Reduction of natural hydrocarbon resources, rise in price of oil and gas production systems, electric and heat energy tariffs increase, environment pollution by emission of carbon dioxide and global warming [1,2] enhance the interest in the use of renewable energy sources. It’s possible to dispose of the large volumes heat by means of cold power generation for manufacture process needs. This is possible by including compressor or absorption conditioners in the heat network diagram. This allows to increase the plant efficiency in summer time. 68 % of utilities have served set time-limit This results in excessive networks losses, the low equipment efficiency factor, excessive accident risk. This requires a higher cost of operation and maintenance of municipal infrastructure.
