玻璃、搪瓷工厂的坩埚熔窑,是一座散发热量的生产设备。据计算(以一般有10只坩埚的熔窑计算),熔窑内加热至1,200℃以上时,熔窑围壁表面和坩埚口散发出来的热量,从原料加热、熔化、澄清、冷却到成型等阶段的24小时内,总共约有350万大卡,平均每小时散发出热量约为15万大卡。熔窑 Glass, enamel factory crucible furnace, is a heat production equipment. It is calculated (calculated as a furnace with 10 crucibles in general) that the heat emitted from the walls of the furnace wall and the crucible mouth is heated, melted, clarified, cooled, molded, etc. in the furnace when it is heated above 1,200 ° C During the 24-hour phase, a total of about 3.5 million kcal will be generated, giving an average of about 150,000 kcal per hour.
