A detailed design is presented of a tokamak power reactor with an electron cyclotron resonance heating system. Major research topics include: physics constraints imposed on the design of a reactor by the ECR wave absorption conditions; design of the high frequency (200 GHz) gyrotrons needed for plasma heating; the gyrotron power and magnet systems; a microwave transmission system in oversize wa...

Combining the transformation project of certain strip steel rolling production line, the techniques process of walking beam heating furnace was elaborated in this paper. The practical application of LOS-T18-2ZC1 laser detector was elaborated. The network communication model of walking beam heating furnace control system was designed. The realization method of production process automation contr...

Koreans usually prefer the district heating system (DHS) to the individual heating system (IHS) because DHS can give them convenience and safety within their living environment. The Korean government thus plans to expand the DHS and requires information about the value that consumers place on the DHS over the IHS, which has not been dealt with in academic literature. This paper attempts to inve...

The article considers the automatic control of air conditioning system in order to ensure possibility their successful operation create specified microclimate parameters serviced premises.

One of the important concerns about the quality of the thermoplastic composite in Automated Fiber Placement (AFP) process is the degradation of thermoplastic resin, resulting from the overheating or the lack of proper heating by the heating system used in the automated fiber placement machine head. Heat transfer between the heating system and incoming pre-impregnated tow is not easy to control ...

This paper introduces a disposable battery-driven heating system for loop-mediated isothermal DNA amplification (LAMP) inside a centrifugally-driven DNA purification platform (LabTube). We demonstrate LabTube-based fully automated DNA purification of as low as 100 cell-equivalents of verotoxin-producing Escherichia coli (VTEC) in water, milk and apple juice in a laboratory centrifuge, followed ...

In Denmark a considerable number of houses are connected to a district heating system. In a district heating system several production units may exist, and for the considered district heating system this is indeed the case. The production cost varies from production unit to production unit – the cheapest is often a waste incinerator plant. The varying consumption of heat means that some units n...

Being with many advantages such as environmental protection, controllable, facilitate measurement etc, electric heating has been promoted actively in some places. For public buildings with huge energy consumption, electric heating intelligent controlling may be the key to achieve energy conservation. In this paper, visual distributed control system (DCS) was presented in electric heating of the...

The concept of exergy is defined and applied to district heating systems. The influence from different reference state conditions and system boundaries are explained in some detail. The aim is to show the simplicity and value of using the concept of exergy when analyzing district heating processes. The exergy factor is introduced and applied for a number of Swedish and Danish district heating s...

Large amounts of energy are wasted because heating systems run round-the-clock even though residents are out or occupy only a small part of their home. Major reasons for this behaviour are the non-intuitive heating controls and missing direct feedback about the heating activity or even energy consumption. In addition, bad ventilation behaviour, e.g. tilted windows, may lead to unhealthy room cl...
