KSHB Förord s 1-8 99-05-10 09.12 Sidan 5 Kanthal Super Handbook Introduction 5 ANTHAL is a world-renowned name within the field of K electric heating and you will find our handbook an indispensable aid when installing and operating our KANTHAL SUPER resistance elements that are designed for all types of electric heated industrial furnaces. When we introduced the now world-famous KANTHAL iron-chromium-aluminium electric resistance alloys in the early thirties this represented a considerable rise in the maximum operating temperature of metallic resistance elements. Again, when KANTHAL SUPER elements were introduced in 1956, this represented a step upwards on the temperature scale for resistance elements. The aim of our R&D department, however, has always been to improve our materials to enable their use at still higher temperatures. Through intense research work, we have been able to raise this temperature from 1650 °C (3000 °F) element temperature in 1956, to 1850 °C (3360 °F) today. New element forms have also been developed and in this handbook you will find information about SUPERTHAL high temperature heating modules. KANTHAL SUPER elements have proved to be very useful not only at high furnace temperatures, but also at lower temperatures, particularly in the field of heat treatment of metallic products in controlled atmospheres and melting of glass. The fields of possible applications are unlimited and have yet to be fully investigated. With the increasing interest in electric heating, we can expect many new designs and applications in the future. In addition to information on the properties of our KANTHAL SUPER material this handbook will also provide data on our standard elements and instructions for element calculation, installation, operation, etc. Further, advice is given on furnace designs, and some examples of actual KANTHAL SUPER element installations are shown in the installation section. We have tried to give you enough information to enable you to calculate and install KANTHAL SUPER elements and how to operate furnaces. If our advice is followed, you will be assured of an efficient and economical installation for your special heat treatment operations. If you need any further advice, specialists at our companies, our agents and the skilled staff at our technical service department in Hallstahammar will be pleased to assist you.

  • The Affordable Heat-Circulating Fireplace Offering Style, Value and Performance. After a Hard Day in a Cold World…
    F I R E P L A C E S Y S T E M S The affordable heat-circulating fireplace offering style, value and performance. After a Hard Day in a Cold World… The NEW-AIRE FIREPLACE SYSTEM utilizes the basic principles of thermodynamics designed into any new high-efficient forced air furnace (radiant, conductive and convective heat transfer). By forcing air movement through a series of baffles in a specifically designed heat exchanger surrounding a steel firebox, ratings in excess of 200,000 BTU can be achieved in a full-fired condition. With 1050 cubic feet of air per minute at central HVAC static pressures, the NEW-AIRE fireplace easily matches the heat output of any high-efficiency furnace on the market today. Your home is the heart of your family’s life. A warm hearth is the gathering place that defines the spirit of the home. The NEW-AIRE fireplace, clad in brass and glass, provides both the traditional and functional elements needed in today’s life. Unlike stoves and inserts, the NEW-AIRE can be independently ducted to provide whole-house heating beyond the walls of the room in which it is installed. Certified to the International Mechanical Code, when ducted to induce heat into the central heating system, the NEW-AIRE SYSTEM efficiently provides the required heat for 4000 plus square foot homes. The NEW-AI Airtight /Airwash Door Control: heat loss, wood consumption, and smoke in the winter — air infiltration and ash smell in the summer. Makes any fireplace more efficient by controlling the “burn rate”.

It also has enormous implications on the architecture of a distribution network. Firstly, the thermal comfort model of the human body was established to analyze the comfortable body temperature of a main crowd under different temperatures and levels of humidity. Secondly, it analyzed the influence factors of electric heating load, and from the perspective of meteorological factors, it selected the difference between human thermal comfort temperature and actual temperature and humidity by gray correlation analysis. Finally, the attention mechanism was utilized to promote the precision of combined adjunction model, and then the data results of the predicted electric heating load were obtained. In the verification, the measured data of electric heating load in a certain area of eastern Inner Mongolia were used. The results showed that after considering the input vector with most relative factors such as temperature and human thermal comfort, the LSTM network can realize the accurate prediction of the electric Citation: Sun, J.; Wang, J.; Sun, Y.; Xu, M.; Shi, Y.; Liu, Z.; Wen, X.
