The decrease of energy sources, the increase of energy need and energy costs, competitive conditions in industry and environmental sensitivity require the effective usage of energy sources. In this study, optimum combustion study by using thermal camera and pyrometer in the correct heat furnace of an industry plant for the effective usage of energy in industry. For this reason, in tempering furnace of a milling roll workshop, in order to control the efficiency of tempering, detect the flame length and color and control the homogeneous tempering, 4 thermal cameras and 4 pyrometers have been assembled to the appropriate locations of the furnace. In the study, the tempering furnace has been observed and the results of observations have been evaluated. The contribution of the changes made to the production has been calculated by the information obtained from thermal camera and pyrometer and has been examined with the date of reimbursement. Possible spare part and production saving has been established as 364,460 $ annually and back-payment time as 3 months. Accident risk that is caused by the hot air and sometimes occurs during the controls has also been reduced so that the workers have been forced to work more safely according to WHS (workers’ health and security).

And Control

To overcome the difficulties of extending the main power grid to isolated locations, this paper proposes the local installation of a combination of three renewable energy sources, namely, a wind driven DFIG, a solar PV unit, a biogas driven squirrel-cage induction generator (SCIG), and an energy storage battery system. In this configuration one bi-directional SPWM inverter at the rotor side of the DFIG controls the voltage and frequency, to maintain them constant on its stator side, which feeds the load. The PV-battery also supplies the load, through another inverter and a hysteresis controller. Appropriately adding a capacitor bank and a DSTATCOM has also been considered, to share the reactive power requirement of the system. Performance of various modes of operation of this coordinated scheme has been studied through simulation. All the results and relevant waveforms are presented and discussed to validate the successful working of the proposed system.

Solar energy is one of the more attractive renewable energy sources that can be used as an input energy source for heat engines. In fact, any heat energy sources can be used with the Stirling engine. Stirling engines are mechanical devices working theoretically on the Stirling cycle, or its modifications, in which compressible fluids, such as air, hydrogen, helium, nitrogen or even vapors, are used as working fluids. When comparing with the internal combustion engine, the Stirling engine offers possibility for having high efficiency engine with less exhaust emissions. However, this paper analyzes the basic background of Stirling engine and reviews its existing literature pertaining to dynamic model and control system for parabolic dish-stirling (PD) system.

This paper deals with energy audit procedure implemented on only Serbian car manufacturer 'Zastava Automobili'. Based on the results of energy auditing and performed technological and economical feasibility studies several energy saving measures were proposed. The measures are related to different energy sources: steam, hot water, compressed air, electricity, and water. Such energy efficiency programs reduce energy costs and increase production profitability of the factory.

Robots have been used in various areas to replace manpower, reduce costs, and facilitate more effective resource allocation. This study sought to assist the business of the bureau by developing two robots using the Robot Operating System. The developed robots have autonomous intelligent navigation functions and are suited to monitor the environment of <br /> the laboratories in the bureau. One robot had a temperature and humidity sensor and an infrared thermal camera, and it could be used to patrol and monitor the laboratory environment. The other robot had drawers in which specimens could be placed; robotic arm in the elevator could coordinate and control elevators, enabling the robot to move and transport specimens autonomously. Plenty of tests were conducted to verify the feasibility <br /> and practicality.

The aim of this research was to find a way to reduce energy costs by using thermal image techniques for investigating the thermal efficiency of ceramic furnaces. The case study was “Ban Nam Jo Ceramic”. The researchers collected the information by performing an in-depth interview at the research area, collecting preliminary data and using the thermal camera in the technical analysis part. The researchers also measured the temperature and volume of gas in the furnace. After that, those data were used to calculate the energy balance and the thermal efficiency of ceramic kilns. The data showed that the first measured furnace had calculated thermal efficiency of 9.99%. After the maintenance, the thermal efficiency increased to 16.64%. Furthermore, the volume of liquid petroleum gas decreased by 40%, and the damage in products after firing decreased by 3 %.

Energy supply represents not only the energetic and ecological undertaking factor of tourist economy bearers, but the factor of profitability and competitiveness within the foreign tourist market as well. Lower energy costs form the prerequisites for higher profit accomplishments, as well as better market price competitiveness. Instead of exploiting natural resources, tourism should make the most of them, which brings into relief the directing of tourist economy subjects towards the use of restorable energy sources, particularly solar and wind energy. In spite of favourable climate features of Croatia, expressed in terms of insulation and windstrength, the restorable energy sources are still used rather insignificantly. Some positive moves in such a trend are noticeable on the island of Pag and in the town of Sibenik, where the electric energy is obtained in wind power-plants. In accordance with the concept of sustainable development of tourism, both solar energy and wind-mill energy should represent the skeleton for the energetic supply of the Croatian tourist coastline in the future. And only then, with the right amount of energy and without dependence on the world energetic markets, Croatia can develop its own healthy economic and tourist future.

The growing increase in world energy consumption favors the search for renewable energy sources. One of the existing options for the growth and sustainable development of such types of sources is through the use of biomass as an input. The employment of biomass as solid fuel is widely studied and is no longer a novelty nor presents any difficulty from the technical point of view. It presents, however, logistic obstacles, thus not allowing their direct dissemination in every organization that is willing to replace it as an energy source. Use of biomass can be rewarding due to the fact that it can bring significant economic gains attained due to the steadiness of the biomass price in Portugal. However, the price may rise as predicted in the coming years, although it will be a gradual rising. The main goal of this study was to analyze whether biomass in the case of the Portuguese textile industry can be a viable alternative that separates the possibility of sustainable growth from the lack of competitiveness due to high energy costs. The study showed that biomass can be a reliable, sustainable and permanent energy alternative to more traditional energy sources such as propane gas, naphtha and natural gas for the textile industry. At the same time, it can bring savings of 35% in energy costs related to steam generation. Also, with new technology systems related to the Internet of Things, a better on-time aware of needs, energy production and logistic chain information will be possible.
