What is the improvement method for the coke oven head? The following is introduced by the coke oven manufacturer:

What are the requirements for the safety of the coke oven, the following by the relevant personnel of the coke oven manufacturer to introduce:

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 erosion and cracks due to the influence of the external cold air flow; the roof brick at the furnace head is also often due to

The exhaust gas produced by the combustion of coke oven gas in the combustion chamber is discharged into the atmosphere through the chimney after recovering part of the sensible heat from the lattice brick of the regenerator. The temperature of these exhaust gases before entering the chimney is 260-300 ℃, and the large amount of waste heat contained in the exhaust gases discharged through the flue and chimney cannot be effectively utilized, wasting the available waste heat energy. With the increase of national energy conservation and emission reduction policies and monitoring efforts and the need for enterprises to improve their competitiveness, such as the recovery of this part of the heat with waste heat boiler system, not only can the reasonable and effective development and utilization of coke oven tail gas waste heat resources, but also can solve the coking production of self-use steam, to achieve energy saving and improve the enterprise's

In the case of ensuring the drying effect of the drying kiln or at least ensuring that the drying kiln does not collapse, the heat extraction of the cooling zone of the baking kiln can be appropriately reduced. According to the heat balance calculation of the kiln manufacturer, the heat required for artificial drying accounts for about 30% of the total heat of the kiln. If measures can be taken to reduce this proportion to about 20%, a large amount of heat can be saved and the degree of under-fire of the finished brick can be reduced accordingly. The measures that can be taken are as follows: a. make full use of the storage line and let the well-coded brick blank be fully dehydrated by the ambient temperature on the storage line. For every 1% decrease in the moisture content of bricks entering the drying kiln, the heat consumption of the drying kiln can be reduced by 6% ~ 8%; B.

On February 10, Wang Zhonglin, deputy secretary of the Hubei Provincial Party Committee and Governor, went to Wuhan University of Science and Technology and Hubei Carbon Emissions Trading Center to investigate the "double carbon" technological innovation and carbon market construction. He stressed: it is necessary to thoroughly implement the spirit of General Secretary Xi Jinping's important speech when he presided over the 36th collective study of the political Bureau of the CPC Central Committee, pay close attention to tackling key problems in green and low-carbon technology, and promote the construction of the carbon market to a new level. we will speed up the construction of a green and low-carbon industrial system and make greater contributions to the realization of carbon peak and carbon neutrality. At the State Key Laboratory of Refractories and Metallurgy of Wuhan University of Science and Technology, Wang Zhonglin listened carefully to the introduction of carbon neutrality related technology projects, and spoke highly of its major economic and ecological benefits; at the Provincial Collaborative Innovation Center for Efficient Utilization of Vanadium Resources, he learned more about vanadium energy storage In the research and application situation, relevant departments are required to increase support and accelerate the industrialization of more carbon scientific and technological achievements. Wang Zhonglin fully affirmed the fruitful achievements of Wuhan University of Science and Technology in climbing the peak of science and technology, and encouraged the school to base on the actual development of Hubei, give full play to the source function of scientific and technological innovation, strengthen the integration of production, education, research and application, and accelerate the transformation of scientific and technological achievements. Make positive contributions to the goal and task of "double carbon"; deepen international academic exchanges and cooperation, strengthen discipline construction, and take the lead in making. At the Hubei Carbon Emissions Trading Center, Wang Zhonglin carefully watched the real-time trading of carbon emissions rights, understood the operation of the national carbon emissions rights registration system, and requested further optimization of the system to ensure smooth and efficient operation and data security and stability. At the subsequent symposium, Wang Zhonglin listened to reports on the construction of the carbon market, green finance and carbon finance in Hubei Province. He pointed out that accelerating the construction of the carbon market is an important deployment of the Party Central Committee and the State Council to promote the "double carbon" work, an important measure to win a greater international voice, and an important action to accelerate the construction of a beautiful Hubei and realize the green rise. It is necessary to raise awareness, speed up the construction of the carbon market, and better empower Hubei's high-quality development. Wang Zhonglin emphasized that it is necessary to effectively build and make good use of the national-level functional platform of the national carbon emission rights registration system, improve system functions, improve service quality, actively expand clearing and other businesses, accelerate the establishment of registration and settlement institutions, and seize the highland of low-carbon development. We should earnestly strengthen exploration and innovation, rely on high-end think tanks, set up professional teams, strengthen research on carbon finance, green finance and other fields, innovate financial products, and improve green financial infrastructure. It is necessary to effectively promote the development of green and low-carbon industries, strengthen the research and promotion of key core technologies, vigorously promote the low-carbon transformation of industries, and cultivate low-carbon emerging industries. It is necessary to earnestly form a joint force of work, actively strive for support, strengthen organizational leadership and overall coordination, and strengthen policy support for talents, finance, taxation, and funds, so as to create a good environment for the development of the carbon market. It is necessary to effectively increase external publicity, strengthen the organization and planning of activities, continuously improve the display and popularity of the Hubei carbon market, attract more resource elements to gather in Hubei Province, promote the accelerated development of the carbon market, and win glory for the development of Hubei and the national green Development adds luster. Vice Governor Zhao Haishan and Ning Yong participated in the survey. (Yang Nianming) (Editor: Zhou Qianwen, Zhang Jun)
