Tunnel kiln does not ignite. Why?

The tunnel kiln fire will not continue for the following reasons:

1, the remote control door of tunnel kiln is too high, and the wind at the bottom of the stack is too strong, which blows away the primer and fails to achieve the expected effect.

2. The kiln worker's unskilled work or wrong operation leads to excessive pumping force of the remote brake.

3. The legs of the kang are too thin and too high, and the wind under it is too strong, which blows away the hot air.

4. If the kiln is built with traditional refractory bricks or used as a fire stop, the refractory bricks will crack and break after long-term use, resulting in unstable air pressure in the kiln. It is suggested that all fibers should be used to replace the original refractory bricks to build the kiln. Ceramic fiber has thermal shock resistance that refractory bricks do not have, and will not crack and powder.

Master the requirements of tunnel kiln temperature

Kiln owners should not only have certain working experience, but also have the savvy to change the operation plan with the change of fire, accurately judge the direction and development degree of fire and what appropriate measures to take.

Kilns mainly have the ability to remember several kinds of fires. When igniting, the internal combustion will change somewhat, the output will also change, and the wind pressure will also change. Before each fire change, how high is the temperature, how long does it take to burn, whether it needs to be cooled or heated, whether there is external fuel, how much to invest, where to invest, what bricks to burn, and so on. All these points should be clarified, straightened out and kept in mind.

Excellent kiln owners have a very low error rate in their work, and it is a common phenomenon to occasionally burn 3~5 cars of defective products every ten days and a half months. One of the main reasons for the high error rate of some kiln workers in their work is that when the fire burned to the state a few days ago, they forgot all kinds of reasonable operations at that time and used the wrong operation methods in their current use, so the quality of the burned bricks can naturally be imagined.
