Furnace of kiln of pottery and porcelain more than heat reclaims fall bad news i
From;    Author:Stand originally

<DIV><FONT&nbspface=Verdana>A of   production pottery and porcelain important process is firing, firing undertake in kiln furnace. The kiln heat that pottery and porcelain produces has continuous (channel kiln) also have clearance type (kiln pouring blaze) , no matter be channel kiln,still pour blaze kiln, its thermal efficiency is lower. The account with small efficiency besides the reason such as combustion loss, heat loss due to radiation, important is smoke evacuation loss. Firing the break an appointment of caustic of quantity of heat that channel kiln waste gas takes away occupies total caloric 20% ~ 40% , and the 30% ~ that pour the quantity of heat that blaze kiln waste gas takes away to occupy specific fuel consumption to measure about 50% . Reclaim so the quantity of heat of kiln end waste gas tries to use is the key that improves kiln furnace efficiency. Temperature of smoke evacuation of domestic channel kiln is in commonly 300 ℃ of 200 ~ , also have be as high as 400 ℃ , the smoke evacuation temperature that pours blaze kiln individually can be as high as 560 ℃ . On one hand kiln furnace smoke evacuation takes away a large number of more than heat, on the other hand for dry blank, a few factories make kiln oven additionally again or boiler generation sirocco and vapour carbonado with satisfying the requirement of dry blank. In recent years, as the ceaseless development of energy-saving technology and promotion, the technology that heat up a canal already in pottery and porcelain flue gas beyond is heated up in reclaiming, get applied. The more than heat in using science and technology of Electromechanical of times of Beijing flourish star to develop limited company to heat up tubal heat exchanger to accept flue gas back and forth heats the heat source that air regards stoving as blank, can obtain better energy-saving result. </FONT></DIV>

<DIV><FONT&nbspface=Verdana>  cooling zone of kiln of channel of electric porcelain works the waste gas of 450 ℃ of 400 ℃ ~ takes out an overheat to run heat exchanger heat exchange, flue gas thermal drop comes 300 ℃ , in returning kiln furnace again firing belt use as atmosphere film wind. The fresh air that is heated sends drying oven, blank of dry report porcelain. </FONT></DIV>
