The article describes the modeling process of the
heating system operation of a livestock-breeding
complex. It presents graphs reflecting the influence of
technological parameters of heat supply system of
cattle-breeding complex with a catalytic combustion
device on the parameters of energy efficiency of the
system and the parameters characterizing the stability
of the temperature conditions in the livestock sector
We have presented a simulation mathematical model of a complex for climate control of beehives that establishes the relationship between the performance parameters of the complex and efficiency parameters with a condition of descent winter maintenance of bees
The article reviews the results of the computational experiment by means of mathematic model of a small bioreactor with the bubble mixing system and catalytic heating. We considered the quantitative relationship between design parameters of a bioreactor and parameters of its effectiveness
The article provides a description of existing catalytic burning units, the rationale for improving the technical solutions of components and parts, and the catalytic burning unit proposed by the authors with a circulating bed of filler
We have presented technical solutions of an energy
supplying complex of apiary based on a solar plant,
which ensure its functioning in the winter. Various
aspects of the influence of the snow cover on the
functioning of the complex are considered in the
article. The favorable effect of the snow cover includes
increasing the diffuse insolation, improving the
thermal insulation of the building for placement of
bees, which protects bee families from fluctuating
external temperature. The negative effect of the snow
cover includes adherence of snow to the receiving
surfaces of solar energy converters, which can lead to
decreasing the efficiency of using of photovoltaic
modules and solar collectors. Both active and passive
methods of combating snow sticking are suggested in
article. Passive methods include installation of solar
energy converters at an angle close to 90°, as well as
their placement on the windward side. The simulation
of the functioning of the complex based on a solar
plant was conducted for climatic conditions of the
Republic of Mari El (the time interval – from 14
October to 14 April, a photovoltaic module area – 1,3
m
2
with installation angles of 72˚ and 88˚). Because of
the simulation, we obtained graphs of the changing the
power of the photovoltaic module. Active methods
include air injection onto the receiving surfaces of
solar energy converters and using of heating elements
The article presents a simulation mathematical model of technical and technological systems for heating livestock complex, which establishes the relationship between the structural and technological parameters of the technical and technological system and the parameters characterizing the efficiency of their operation in the process of heat transfer at the heat supply of the livestock sector
The article describes the details of modeling of catalytic systems for the production and conversion of energy in anaerobic digestion of organic manure. We have also presented a simulation mathematical model that establishes the relationship between structural and technological parameters of catalytic systems and the parameters characterizing the efficiency of the catalytic system in the production and conversion of thermal energy in the anaerobic treatment of organic manure
The article describes the common operation principles of catalytic systems within animal production unit, for improving the design solutions and the description of catalytic systems developed by the authors for production and conversion of energy for the anaerobic recycling of organic waste
The results of numerical experiments on the simulation of mathematical models of the functioning of the technical and technological systems for heating livestock complex have been presented in the article. The equations that establish a quantitative relationship between process parameters and the parameters of the efficiency of the heating system have been shown
The article presents the modernization option of the
forest residue furnace that allows speeding up the
drying process by boosting it. The dependencies,
reflecting the influence of the temperature of the
drying process on the heat losses of the furnace and the
effect of the load and the moisture content of the
feedstock to the fuel consumption for the entire drying
process, are presented in the article
