Traditionally, the ceramic industry is a high pollution, high energy consumption industries, with the introduction of relevant national policies, and enhance the awareness of environmental protection industry, "low carbon", "environmental protection" the voice sounded in the ceramics industry, industry is truly toward the direction of energy saving and emission reduction.

The development of ceramic industry, ceramic machine depends on the progress, therefore, ceramic machine industry in recent years has also carried out a series of reforms, make energy-saving environmental protection. Especially the raw material and energy prices rising, the "energy saving" has attracted more attention of the industry. In May 28th to 31 on the "2012 China international ceramics technology equipment and building ceramic sanitary ware products exhibition" (hereinafter referred to as the "Guangzhou ceramics exhibition"), "energy-saving emission reduction" once again become the ceramic machine enterprises pushing new climax.

Kiln, is the key equipment in the production of ceramic kiln, the structure is reasonable, the selection is correct, is directly related to the quality of products, production capacity and energy consumption level. Guangzhou ceramics exhibition, kiln has become a indispensable scenery, has become the focus of attention of the purchaser. By visiting kiln production enterprises and supporting enterprises, the reporter found, the kiln continues to progress, improvement of almost all progress, all around the "energy saving and emission reduction".

Wide kiln Development Trend

In the middle of the gold roller booth, nearly ten long roller stands, surrounded by a small circle. Ring roller senior engineer Li Junling told reporters, this is wide kiln with high temperature resistance of the roller. Li Junling said: "now do kiln enterprises in energy saving and emission reduction to the direction, to reduce energy consumption in the production of ceramic enterprises, reduce the cost. Broad kiln is a developing trend, its output, improve production efficiency, but also reduces the energy consumption of natural."

Li Junling said, with their Kodak, Peng machinery companies have cooperation, and, these enterprises in the furnace this one continue to do structural optimization. This statement in Peng machinery marketing general manager Deng Zhifen received confirmation. Deng Zhifen said, the future is certainly withwidebody kiln kiln production, Peng in the now 3.15 meters wide, 400 meters long wide body kiln enterprises have been put into use, and stable performance.

Modena commercial director Wu Junliang also think, ceramic enterprises to reduce the cost in production, is to reduce the energy consumption of two is by itself. The key is to increase the yield of the kiln inner width, reduce heat consumption and heat dissipation of the kiln wall, increase the rate of energy saving. According to reports, the fuel consumption of Modena broad kiln has been as low as 415cal/kg.

Kiln / Gacoing, this is a way to optimize the kiln structure, aims to increase productivity, reduce energy consumption per unit area of the product. In the national "1025" planning, length of 100 meters below the kiln has entered the ranks of elimination, because these small kiln in the utilization of waste gas, waste heat recovery, product quality and other defects in many aspects. However, there are also some broad kiln technical difficulties. For example, the temperature in the kiln, touch the problem of angular deformation.

However, these problems through continuous debugging, improvement, has been effectively solved. For example, the length of the gun, the furnace temperature uniformity, thereby reducing the color of ceramic products, the problem of deformation; through the improvement of roller, increase the stability of the brick feeding, reduce the collision deformation.

Wide kiln is a kind of development trend, meet the demand of energy saving, however, is not the longer the better and more wide kiln. The width and length of the kiln, still need to match with the application of the actual situation of the enterprise, such as product specifications, the factory covers an area of and so on. Marketing Director of Huanggang Zhongci kiln kiln Co., Gao Jianxin said: "the broad kiln is a trend, but the ceramic industry has been in the production promotion efforts of the times, now need to do is to enhance the quality, innovation, so, broad kiln to achieve emission reduction, more need to carry on based on the demand for enterprise production, not blindly increase the extension."

In addition to broad kiln, multilayer kiln is a trend. In Peng machine booth, the reporter saw multilayer drying kiln display materials, it has a small footprint, high energy utilization rate advantage. South China University of Technology Professor Zeng spoke at the kiln development, also mentioned the development advantages of multilayer kiln, and puts forward the multi-layer kiln in the operation is troublesome, installation and maintenance is more complex, and the optimization of space.

Directions: details, complete and perfect, improve the product excellence rate

In this exhibition, many enterprises in the market this year sigh is not good, but also not pessimistic. "Ceramic enterprise crisis, is our opportunity." This sentence, more than once from the mechanical equipment of business operations, management personnel mouth. They think, building ceramics industry suffered a crisis, the difficulty of development, this time, the industry faces reshuffle and change. As we all know, change, many enterprises will be eliminated, and stay strong, is the future of the industry. How to become a strong change, innovation?.

In order to meet the demand of ceramic enterprises, ceramic machine enterprises are constantly adjusting their. Gao Jianxin said, the current furnace technology has been mature, the development direction of energy saving and emission reduction is a, is a perfect detail, there is a promotion service. The details of the adjustment, in fact, also part of energy saving and emission reduction. Whether it is through the regulation of the gun or the improved roller lifting, the aim is to improve product quality, reduce the waste of resources.

The kiln use, especially the use of wide kiln, brick, tile, disorderly slow color and other more common problems. Due to the market downturn, the fierce competition, the profit space of ceramic products has been compressed, enterprises want to survive, must at the same time to ensure the quality of the lowest cost. Deng Zhifen told reporters, competition in the future lies in the kiln, the excellence rate of the products, the business requirements of equipment will be more and more high, the degree of precision in the production process also need to improve, so, according to the needs of enterprises, to do detailed debugging. Deng Zhifen said, in the future there will be a Peng integration equipment and services, close to the enterprise demand from details. Now, they have according to the needs of foreign customers to do the drying kiln closed, there are some customized equipment according to customer demand, and used in the Peng machine roller, and according to the requirements of the equipment, draw good drawings, to the roller factory.

Wu Junliang, now the main Modena on the furnace efficiency improvement, improvement in the details, such as the combustion system, recovery system upgrade. At the same time, according to the current broad kiln will appear uneven heating problems, continuous improvement in combustion technology. Wu Junliang said, firmly believe that the innovative achievements of the future Modena, Modena this exhibition to launch a series of products, including patent product of MFP sheet furnace is a typical equipment fine. The equipment used in a sheet of THINKERA products, the sheet thickness is only 3mm, the specifications of up to 1.2 x 3 (m).

In the process of kiln detail perfect, manufacturers also use roller kiln according to the problems in the process of doing, do everything in one's power improvement, solve the chaos, such as anisotropic bar brick a brick, slow collision angle and deformation. There are super roller firing, specifically applicable to color code, such as brick plate. In addition, there are flowers inside the ceramic roller, enhance the bearing capacity of fine rod roller, to prevent the firing process of the roller deformation loss caused by product.

In addition to the roller, gas furnace supporting also has an effect on the use of the products in the kiln top rate. At present most of the ceramic producing areas of China using gas generator, coal gas technology has been very mature. Foshan Okun machinery limited company chairman Zhao Qiusheng told reporters, coal gas will have some impurities mixed in the gas, will give ceramic products especially the appearance of sanitary ware products bring defects. Now the gasifier through the development and improvement of the use of advanced technology, the impurities in the gas filter, so that the kiln cleaner, reducing gas impurities caused by problems in production.

There is a large space to improve the furnace industry

In the interview, many enterprises and technical personnel, the current building ceramics kiln has been very mature, have greatly improved and improved, more is to take the road of energy saving and emission reduction, improvement in the details, facilities, services, and daily used porcelain and sanitary ware kiln furnace, a large room for improvement the.

However, there are different voices from the relevant experts and technical personnel in enterprises. Zeng believes that at present, kiln intelligent control degree is relatively low, change of fuel, temperature control instrument, still need to adjust the manual, this adjustment will be working experience, the impact of mental state, easy to cause the adjustment is not precise, which caused some problems in production. The future direction of development, the system can automatically adjust, enhance the accuracy and process according to the environmental changes, to ensure the stability of production.

Diamond roller technician Shen Daoyuan also thinks, the furnace industry in technological innovation of this piece also have a brilliant future, the intelligent automation, is the most important of this piece of kiln. "Part of this also belongs to the furnace industry to explore the road of sustainable development." He believes that, although the furnace does not require a lot of artificial intelligence, automation, but in addition to the more precise control of energy consumption, make the production more stable, but also can reduce the workload of other links in the production.

In addition, with the implementation of national policies, the industry in a large number of old kilns will be eliminated, new efficient furnace will increase market share. But how these old kiln was improved on the basis of the original, but also a need to think about. I met a reporter from Shandong over the purchaser in the exhibition hall, he had no definite purchase goal, just to have a look the new development of this piece of ceramic equipment. He told reporters, according to his understanding, now a lot of kiln ceramic enterprises or old kilns, now the country about energy saving and environmental protection, the elimination of old kiln is inevitable, but the kiln out from a certain angle, it is a waste of resources. Lower carbon, is to transform these old kiln, to meet the requirements of sustainable development and energy saving and environmental protection.

Energy saving and emission reduction is represent the general trend of ceramic production, but in energy saving and emission reduction in the process of enterprise investment in human resources are many, it also increased the difficulty of implementation. Wu Junliang also believes that, although the state has repeatedly issued a policy, but the energy saving and emission reduction is a huge project, many enterprises, although the heart is unable to, can only take it easy.
