Product Description

Raw materials are melting in cupola furnace with water cooling system. Lava flows out from the side hole at lower part of cupola furnace, and then lava flows through fix launder, and flows into movable launder and falls on centrifuge. Lava will be fiberized under the centrifugal force produced by centrifuge rotating at high speed and high speed air flow from air ring. There is level controller installed at the top of cupola furnace, it can keep the cupola furnace material in level and control the temperature of waste gas in steady. The composition of waste gas contains: CO2, CO, SO2 and dust. For controlling the contamination, saving energy and increasing the melting temperature and promote the stability of lava, the cupola furnace needs to be installed with waste gas burning and preheating system of combustion support air of cupola furnace, as dust remover, waste gas burning furnace and heat exchanger. This system will separate the dust out from waste gas and burns the harm composition as CO and H2S, and then the air will be released into atmosphere. In order to make full use of energy, the high temperature waste will be intook into heat exchanger to preheat the combustion support air which will be blown into cupola furnace to assist burning.
