These three CHPP zones are now operating under the parameters that are prescribed in the standards. Our research has shown that each zone requires its own optimal parameters in order to raise the CHPP units efficiency: increase the reliability of heat supply and reduce fuel costs, " said Denis Sinelnikov.
Today, the main factor of pipelines corrosion is the temperature of hot water and its chemical composition. The higher the temperature, the greater the rate of corrosion propagation inside the pipes. With an increase in water temperature from 50 to 75°C, oxygen is intensively released from the water and the corrosion rate increases by about 35 %.
The software of NSTU NETI scientist will allow a quick determining of the pressure and temperature indicators that can be reduced to solve the problem of water overheating. Water flow control and automatic temperature control in the hot water system will ensure that the required water temperature in the system is maintained at a constant level.
"The calculation method and software allow analyzing the operating modes of the equipment involved in the production of electricity and heat, as well as indirectly analyzing the occurrence of damage to the pipelines, even though today the main reason for these accidents is not excessive loads and the spread of corrosion inside the pipes, but the unusable pipelines which simply need to be changed," commented Denis Sinelnikov.
Research and development of the software took four years. Today, the software and hardware complex is patented and has already been tested at Novosibirsk CHPP-2.
Denis Sinelnikov plans to expand the research area within the program and consider the heat supply system from the Central Heat Source (CHPP) to the consumer. Now the system works at the CHPP level.
