Abstract:

A method has been proposed to prevent anthropogenic emergencies caused by fire in the premises, based on using the current measure of increment recurrence in the vector of the gas environment state in order to detect possible dangers of maintenance personnel injuries and equipment destruction in the premises. The proposed measure makes it possible to monitor the dynamics of the gas environment state and to identify dangerous states caused by the emergence of fires in the premises at a facility. It has been shown that the gas environment in the premises a means for the transition of impacts fro

Abstract:

The turbulent air environment in industrial premises intensively affects the characteristics of air and heat and gas jets and thereby the effectiveness of various industrial ventilation devices. This effect manifests itself in the accelerated expansion of the main sections of the jets and in the reduction of their range of action. Until recently, the influence of the intensity of air turbulence was not taken into account in the corresponding calculation and design methods. The article proposes methods for calculating air jets and the efficiency of open local suction, taking into account the in

Abstract:

Kitchen and food wastes discarded from the food related premises contributes to the high proportion of organic waste that end up in its landfill. The methane gas released during the dumping of food waste at the landfills is unsafe because the gas is flammable, and it is also a strong greenhouse gas. To tackle this problem, efforts are necessary to reduce the kitchen waste generated and to manage the disposal of waste sustainably. However, for this initiative to be successful, the owners and workers in food sector play an important role. The main objective of this study was to evaluate the prac

The proposed approach enables the transition from two-position (“On-Off”) control to a three-position ventilation drive control mode using an adaptive characteristic derived from a PID control
