About coke oven equipment furnace column, pull bar how to install? The following is introduced by the small series: furnace column is the protective plate pressed on the furnace body, and support the furnace door frame and furnace door close to the protective plate. Furnace column is made of steel plate processing H beam components, due to the different installation position, furnace column has different components, so in the furnace column processing and installation must pay attention. The furnace column shall be numbered according to the design requirements after processing and can be installed after acceptance. The upper and lower horizontal bars pressurize the upper and lower ends of the furnace column to the furnace body through springs. The bars are made of whole round steel. Before installation, check the length, diameter, quantity and thread length of the bars. However

The leakage of the furnace door is one of the main pollution sources of the coke oven. In addition, the improper carbonization chamber of the furnace door will cause the waste gas in the carbonization chamber to escape under positive pressure, affecting the recovery of coke oven gas and chemical products. At the same time, the waste gas will deteriorate the operating environment and burn out the iron parts of the furnace, causing the coke oven body to be easily damaged and shortening the service life of the furnace body. At the end of coking, due to pressure fluctuation of gas collecting pipe and other reasons, air will leak into the carbonization chamber, causing serious damage to the graphite in the brick seam of the furnace wall, causing the furnace wall to leak each other, burning off part of the coke at the same time, increasing the ash content in the coke, reducing the quality and output of the coke. Therefore, the tightness of the furnace door is very important to prevent smoke, fire and

In order to prolong the service life of the kiln, it is necessary to do a good job in the daily maintenance and maintenance of the kiln. The specific contents of the kiln maintenance are as follows: when the kiln is overhauled 1.1 to the contents of the kiln maintenance, it is mainly implemented from the following aspects. a. Check whether the roasting ground is flat. B. Check whether the air duct is unblocked? What is the sealing condition of the air damper? Will there be air leakage during use. c. Check whether all arch bricks on the kiln are loose. d. Check whether there are cracks on the kiln body. E, check whether the kiln door vault has the phenomenon of brick falling, verify whether the straight wall at the kiln door is in good condition, whether there will be no unevenness when blocking the kiln door

The kiln sometimes deforms the equipment during the firing process. The reasons are as follows: 1. The surface temperature is high, the bottom temperature is low, and the brick is easy to "concave" and tilt angle. 2, the surface temperature is low, the bottom temperature is high, the brick is easy to "arch" and corner hook. 3. The front temperature is insufficient (the temperature is too low, the area is short), and the brick is easy to arch or concave. 4. The medium temperature stage is too short, the temperature rises too fast, and the brick is easy to "wave-shaped" deformation. 5, medium temperature is too high, high temperature is too high, brick is easy to fire deformation. 6. The front temperature and medium temperature are insufficient, and the surface temperature of the high temperature section is too high, which is easy to cause the front angle to become warped and the back angle to be deformed. 7. The last 1 at the end of the high temperature segment

Coke oven in the long-term use, by high temperature, mechanical force and physical, chemical reaction and other effects, the furnace body aging and damage is inevitable. What are the main reasons for the aging and damage of the furnace body? Next, the coke oven manufacturer will introduce it to you. (1) Effect of temperature change. In the production process, when the furnace door is repeatedly opened and closed, coal is loaded and coke is extracted, the thermal stress generated by the temperature change of the inner and outer surface of the furnace wall causes the furnace wall to be denuded or cracked. As the furnace age becomes longer, the degree of damage increases and extends into the furnace; the coal loading mouth is also prone to denudation and cracks due to the great influence of the external cold air flow; the roof brick at the furnace head is also often made
