Thermal and Aero Models of Gas Tube Boiler Processes

Providing residential complexes with electricaland thermal energy is becoming one of the prioritiesof Ukraine. Destruction of the infrastructure ofresidential complexes requires prompt restorationof energy systems. Gas-tube boilers are a goodoption for quickly installing thermal generation inboth residential and industrial complexes. The mainfeature of such boilers is the organization of thedynamics of thermal and aero processes in pipes withhot flue gases. Numerous studies indicate problemswith ensuring the intensification of heat transfer atthe gas-metal interface and analyzing the results whencomparing changes in thermal and aero processes.Ambiguities in the analysis of energy changes provideconflicting recommendations for the development ofnew boiler designs.The aim is to increase the power and improvingthe energy performance of gas-tube boilers byintensifying heat exchange during heat transfer atthe gas-metal interface, ensuring moderate changesin the resistance of the elements of the gas pathof the boilers. The need for massive restorationof heat supply systems for residential complexesmakes the issue of improving boiler equipment withsimple structural elements and ensuring high energyperformance relevant.To increase the visibility of thermal and aeroprocesses and the possibility of analyzing researchresults in order to improve equipment, two graphicalmodels for representing the dynamics of thermaland aero processes based on resistance coefficientsand dynamism coefficients are proposed. Newmodels require rethinking and reworking of lawsrepresenting the dynamics of various types of energyprocesses. Ensuring similarity and unification of thedynamics of electrical, thermal and aero processeswill make it possible to correctly combine changes inenergy parameters and proportionality coefficientsof dynamics and potentials when performing tasks ofimproving equipment channels and systems. Visualenergy models should simplify the analysis of resultswhen searching for solutions to increase the thermalpower of various energy equipment.
