The increasing of efficiency and economy of the operation of the energetic equipment under different kinds of fuel and conditions of the load control

The experimental curves of the creep and the long-term strength of 25Kh1M1FA steel have been scientifically substantiated and proved by studying of the rotor of power unit No. 9 on the Luganskaya TES which had worked 275 thousand hours and reproduced all aging processes for the entire period of operation. The experimental curve of the long-term strength is supplemented taking into account the creep, which was limited a range of 175 thousands hours, up to 375 thousands hours.
Based on the experimental work which had been carried out at the Tripoli TES, engineering directions of work have been identified that do not require extensive research when applying solutions for moving in a closed pipeline system of coal dust with high concentration under pressure in a transport agent with unloading through normally provided dust separators.
The possibility of an efficient operation of the burner device of the stabilizing type with the microfuel combustion of alternative gases of different composition due to the self-regulation of the working process was substantiated and proved. Burner devices are characterized by a significantly wider coefficient of working regulation - up to 10 (normal 5) and the ability to work when changing the excess air factor from 1.02 to 10 (in traditional analogues from 1.02 to 1.3).
The advanced automatic control system has been developed, which consists in studying the limits of the change in the parameters of the object under which the system with the received regulator remains robust. This makes it possible to improve the quality of control systems on the basis of regular PID regulators of the automatic control system at the TES of Ukraine. The main directions of construction of modern information control systems are studied, the architecture and software algorithmic support of the automated real-time information system is developed, which performs the functions of the collecting and the preliminary processing of signals from various sensors.
At the results of the development of automation systems for fuel equipment will be worked out methods and algorithms that provide for combustion that is close to optimal in the use of fuels of different quality and variable operating modes of the equipment. Well-known scientific developments are focused mainly on boilers of a small and medium power, the proposed in the work approaches will allow to apply modern developments in large-scale power engineering which is taking into account the instability of the fuel composition. The developed systems of automatic control will ensure a high quality of control when the transmission factor of the object is changed by a factor of 2, the time constant and the time of transport delay of 1.5 times.
