The energy saving method of shuttle kiln.

Shuttle kiln operation flexibility, production can meet more variety, but because it is intermittent burning, its heat loss and heat loss is big, so after improvement of kiln more in line with the concept of energy conservation and environmental protection. So how does it improve energy efficiency?

The energy saving mode of the shuttle kiln is realized by the addition of waste gas preheating device, which is the heat exchanger. General in 1350-1650 degrees, the kiln temperature flue outlet temperature in 1100-1400 degrees, so there is plenty of waste heat, heat utilization only 20-40%, if using a heat exchanger, the heat of the flue can be recycled, recovery of heat from combustion air, drying, or for other purposes.

If the metal heat exchanger is used, the waste heat recovery can be carried out. However, if the temperature of the flue is above 800 degrees, the metal heat exchanger can easily be damaged by high temperature and cannot achieve the purpose of waste heat recovery.

Such as ordinary circumstances the kiln temperature higher than 800 degrees, and the flue temperature is lower than 800 degrees, this kind of situation looks suitable for metal heat exchanger, but if there is a power outage, gas quantity is big, lack of combustion air volume, etc., can make the flue temperature higher than 800 degrees, fast to make metal heat exchanger was quickly burn out.

However, the ceramic heat exchanger has overcome this difficulty. The ceramic heat exchanger has the following characteristics:

1, high temperature resistance, corrosion resistance, so you can put the ceramic heat exchanger in shuttle kiln flue outlet close, higher temperature, then its waste heat utilization rate is high, the heat transfer effect is good, energy-saving rate is high. But the metal heat exchanger was quickly burnt out in the ceramic heat exchanger.

2. The ceramic heat exchanger is several times or several times as long as the metal heat exchanger.

3, if you don't use heat exchanger, the combustion air temperature is generally at room temperature (10 ℃ and 40 ℃), but by ceramic heat exchanger heat of combustion air temperature can reach 300 ℃ to 800 ℃, can not only achieve the goal of energy saving, and improve the environmental benefits.

The stand or fall of shuttle kiln energy-saving way mainly with the choice of the types of heat exchanger has much to do, the user can according to the temperature in the actual production conditions to determine how the heat exchanger to achieve energy saving.
