The dynamic stochastic model of a boiler unit
Journal of Physics: Conference Series, 2021 Abstract The goal is to develop a model that takes into account the boiler unit furnace device dynamics. The D J Box and G Jenkins technique used to identify the steam production process is considered. As the object of the study selected a boiler unit, which is quite complex and interconnected.

EVALUATION OF THE APPLICATION OF COGENERATION UNITS IN BOILERS
National Association of Scientists, 2021 In the global energy sector, there is a steady trend towards an increase in the production and consumption of energy. As the analysis of the technology has shown, mini-Thermal Power Plants (TPP) are one of the key solutions to the problem. The construction, as well as the reconstruction of existing boiler houses in the mini-TPP will not only ensure ...

Adaptive simulation of boiler unit performance
Energy Conversion and Management, 1998 Abstract Industrial boilers of a particular type will behave differently due to manufacturing or assembly tolerances. In addition, the performance of a boiler will vary at different times of its service life. The objective of the present study is to simulate a boiler unit.

Features of Using the Regulatory Method "Thermal Calculation of Boiler Units" for Firetube Boilers
Ventilation, Illumination and Heat Gas Supply, 2018 In recent years, the practice of using fire-tube and fire-fighting water-heating boilers in the replacement of service water heating boilers in boiler-houses has become commonplace in the district heating systems of the cities of Ukraine. In this case, fire-extinguishing boilers can be used both imported and domestic.

A heat recovery unit with phase change material for combi‐boilers [PDF]
Energy Storage, 2019 AbstractA novel heat exchanger (HEX) with phase change material (PCM) is proposed to recover the waste heat from the flue gas of a combi‐boiler. The thermal energy that is recovered from the flue gas is stored within the PCM‐HEX when the combi‐boiler works in the central heating mode.

A simplified non-linear model of a drum boiler-turbine unit† [PDF]
International Journal of Control, 1972 In the analysis of power systems it is highly desirable to have models of the different power generators. In this paper we present, a model for a drum boiler whose purpose is to describe the gross behaviour of the boiler. The major control variables are fuel flow and control valve setting. The output variables are drum pressure and active output power.

Analysis of emissions during the combustion of pellets in boiler units
Technology audit and production reserves, 2022 The object of research is the technological process of burning pellets in boilers. Using solid fuel boilers on pellets for heat production, they are trying to reduce dependence on hydrocarbon energy resources. Often such boilers are installed for autonomous heating of schools and other communal facilities.

Control reconfiguration of a boiler-turbine unit after actuator faults
2016 4th International Conference on Control, Instrumentation, and Automation (ICCIA), 2016 Boiler-turbines are one of the most important parts in power generation plants. The safety problem in such systems has always been a special concern. This paper discusses the application of control reconfig uration by fault-hiding approach for a boiler-turbine unit. In Fault-hiding approach, after occurrence of a fault, nominal controller of the system
