The scope and variety of energy-saving furnace comparison
1, shuttle kiln. Gap-type production furnace, suitable for small batch production of many varieties, due to production flexibility, a lot of small ceramic porcelain are also using this furnace. However, as is the gap type, kiln wall, car endothermic energy consumption to the total energy consumption is relatively high in comparison, but through the efforts of the furnace design and manufacture, such as high-speed burner fast firing, use of lightweight fire-resistant insulation materials reduce the regenerative, and some rapid firing shuttle kiln has reached the old tunnel kiln with comparable energy efficiency.
2, the tunnel kiln. Named amazingly, it's like a tunnel kiln. In fact, in the broad sense includes roller kiln tunnel kiln, tunnel kiln car, pushing plate kiln, tunnel kiln rotary kiln belongs to the range. Narrow the tunnel kiln. We refer only to car tunnel kiln, but the popular name called tidal push board kiln, heard five years ago really put me in Chaozhou confused, in fact, I have to explain, push board kiln is a direct bearing on anti-HPL temperature of the rail, (such as rail or corundum brick just king rail can place the ball rolling) and then a piece of HPL, the thrust bearing is limited by the HPL, generally not long, then twenty meters long, a short while Jimmy, the general or special ceramic powder sintering temperature, not output.HPL as direct push forward propulsion, called the push board kiln. But here are used to it, I know the push board kiln is a Chaozhou tunnel kiln car. The continuous production tunnel kiln, preheating zone is basically the heat of flue gas from the firing zone to bring the heat supply, unlike the shuttle kiln kiln kiln wall, there is no cycle of heating and then cooling the heat loss, firing zone Most of the high temperature flue gas heat to use, so energy than the gap effect kiln. However, due to car or to go through heating and then cooling, waste some of the heat, its temperature is less than the energy saving effect and the roller kiln.
3, the roller kiln. High temperature ceramic rod is driven directly HPL forward, loading the product on the HPL direct bearing on sticks, also known as roller kiln. We first introduce a firing wall and floor tiles, no pallets, floor tile directly on the club, due to the preheating, firing and cooling process in the minimum temperature, firing time from our past with the shuttle kiln, tunnel kiln firing a dozen hours, about twenty minutes shorter, and therefore extended to the art of ceramics, porcelain and ceramics, along with improving the quality of clubs, from low temperature to high temperature phase transformation.As roller kiln is a direct bearing on the place HPL sticks on a rolling forward, it does not like to use one tunnel kiln car absorbed much of the heat, it's airtight than the tunnel kiln is much better. So it is better energy than the tunnel kiln, one of its biggest drawback is the high temperature reduction firing products, high quality requirements of the sticks, the use of silicon carbide rods, can be solved within 1350 ℃ high temperature firing of ceramic products percent. But it does not solve the kiln glaze, crystalline glaze firing, because it is faster.
The above analysis, the shuttle kiln, tunnel kiln, roller kiln structure and the general advantages and disadvantages of enterprises according to their product mix, production, and financial capacity to choose for your furnace:
1, for the production in the following 20m Web, and more product categories, a firing temperature, due to its own output difficult to meet the output of the tunnel kiln, recommended adopting fast-fired shuttle kiln.
2, for output to or greater than 20 m³, but the glaze complex, such as crystalline glaze kiln to be a certain temperature and cooling time, from your consideration of the economic construction of the kiln, shuttle kiln can be traditional or electric shuttle kiln; if You kiln glaze or only partially crystalline glaze, you can choose fast kiln, the kiln is not only faster speed can also be slow. Slow, temperature control is very small. But the slow effect of energy saving difference.
3, to yield large, high altitude, heavy weight, high temperature, single-glaze, the choice of car tunnel kiln. Such as high temperature ceramics for daily use, sanitary ceramics
4, the temperature at 1300 ℃ within the larger artistic production of ceramics
Electric kiln and gas kiln advantages and disadvantages: Electric furnace heating element does not produce the smoke, only the green body in the firing process itself volatile discharge, in terms of shuttle kiln furnace can be sealed, only a few rows pores, no smoke with out heat. Following the firing temperature 1200 ℃ oxidation firing, and now the cost of production lower than the gas kiln. It is estimated that 0.8 yuan in electricity / kWh, gas price 6.2 yuan / KG, the price ratio is a balance. With continuous electric roller kiln firing below 1220 ℃ oxidation products, and now the cost of production lower than the gas roller kiln more than 15%, but more than a 200kva transformer, this investment is not small, there is surplus of transformer capacity ceramics factory,In the preheating zone or near the firing zone with a heating installation of the hotline to warm temperature, high temperature with or with gas, but can not burn to restore electric kiln for firing more than 1260 ℃ high quality requirements of the heater more expensive . Fired heaters above 1280 ℃ to use silicon-molybdenum rods. Silicon-molybdenum rods easily aging, life is not too long. Price depends on selection of electric furnace, the average tariff can choose areas of low electric furnace, the higher the price, the high price of gas in the case of the modification of the original electric furnace is cost-effective, but gas to keep the original function.
