Furnace"},"content":{"rendered":"<p><span class=\"notranslate\">Furnaces can be classified according to the fuel, the heat flow \/ circulation fire, shape, heat contact, manner of operation \/ combustion process, use, and inventor.<\/span> <span class=\"notranslate\"> But of the various classifications will only be explained in part.<\/span><\/p>\n<p><span class=\"notranslate\"> <strong>a.<\/strong><\/span> <span class=\"notranslate\"> <strong>Furnace classification according to the fuel<\/strong><\/span><br \/>\n<span class=\"notranslate\"> Any combustible material can be used to burn ceramics, although it always starts with the burning of wood fuel, while in the recent development of oil and gas combustion using.<\/span> <span class=\"notranslate\"> Now a new heat source for firing ceramics is electricity.<\/span> <span class=\"notranslate\"> Type furnace based fuel (heat source) used can be classified into five types, namely:<\/span><\/p>\n<p><span class=\"notranslate\"> <strong>1) Furnace gas fuel<\/strong><\/span><br \/>\n<span class=\"notranslate\"> This type of furnace using gas fuel, if in Indonesia known as liquefied petroleum gas (LPG).<\/span> <span class=\"notranslate\"> The furnace is very practical and operational costs are quite economical.<\/span> <span class=\"notranslate\"> Reason is what causes many ceramic industries using furnace gas as the main burner.<\/span> <span class=\"notranslate\"> The furnace must be operated with correct procedures and safety standards are high, considering the fuel gas is invisible and extremely flammable.<\/span> <span class=\"notranslate\"> We can set the furnace atmosphere with this gas furnace.<\/span><\/p>\n<p><span class=\"notranslate\"> <strong>2) Electric Furnaces<\/strong><\/span><br \/>\n<span class=\"notranslate\"> Furnaces of this type are widely used in studios or in schools because it is easy to operate.<\/span> <span class=\"notranslate\"> The furnace is equipped with coils that will smolder when electrified.<\/span> <span class=\"notranslate\"> Shape, volume, and specifications of the electric furnace is very varied and each has its own advantages.<\/span><\/p>\n<p><span class=\"notranslate\"> <strong>3) furnaces solid fuel (wood, coal)<\/strong><\/span><br \/>\n<span class=\"notranslate\"> This is the type of furnace that is the forerunner of the ceramic combustion.<\/span> <span class=\"notranslate\"> Until now wood-burning stove is still used in the centers of traditional ceramics.<\/span> <span class=\"notranslate\"> Other solid fuels are wood chips, rice husks, dry leaves and garbage.<\/span><\/p>\n<p><span class=\"notranslate\"> <strong>4) Furnace fuel oil<\/strong><\/span><br \/>\n<span class=\"notranslate\"> When oil prices are dirt cheap, this furnace is very economical.<\/span> <span class=\"notranslate\"> But this time the kerosene stove is rarely used because of the cost of expensive operations.<\/span><\/p>\n<p><span class=\"notranslate\"> <strong>b.<\/strong><\/span> <span class=\"notranslate\"> <strong>Classification Furnace according Directions Heat Flow \/ Circulation Fire<\/strong><\/span><br \/>\n<span class=\"notranslate\"> <strong>1) Furnace fire rises (up draft kiln)<\/strong><\/span><br \/>\n<span class=\"notranslate\"> In the furnace of this kind of heat from flowing into the combustion chamber space heating \/ burning on it and heats the goods there and then out through the chimney at the top.<\/span> <span class=\"notranslate\"> The amount of fuel used in furnaces of this type are relatively large and the temperature difference between the bottom and it was large enough to affect the outcome.<\/span> <span class=\"notranslate\"> Which includes this type are fields and furnace bath furnace.<\/span> <span class=\"notranslate\"> Shape furnace caught fire there were some are square and round.<\/span> <span class=\"notranslate\"> The characteristics of a furnace rises is:<\/span><br \/>\n<span class=\"notranslate\"> a).<\/span> <span class=\"notranslate\"> rather wasteful fuel consumption,<\/span><br \/>\n<span class=\"notranslate\"> b).<\/span> <span class=\"notranslate\"> the combustion temperature is relatively low (below 1000 <sup>\u00b0<\/sup> C),<\/span><br \/>\n<span class=\"notranslate\"> c).<\/span> <span class=\"notranslate\"> temperature difference of the top and bottom and the middle is quite large (bottom higher),<\/span><br \/>\n<span class=\"notranslate\"> d).<\/span> <span class=\"notranslate\"> manner of operation is easy, and<\/span><br \/>\n<span class=\"notranslate\"> e).<\/span> <span class=\"notranslate\"> costs of construction and maintenance easier and cheaper.<\/span><br \/>\n<a href=\"http:\/\/www.tneutron.net\/seni\/wp-content\/uploads\/sites\/7\/2015\/12\/image-23.png\"><img loading=\"lazy\" decoding=\"async\" title=\"image\"
