Waste heat power generation "cement" coming of age

Source: Time:2014-03-25 09:56:17 views:

With the waste heat power generation technology is increasingly mature and state support for energy saving and emission reduction, more and more waste heat utilization of enterprises are aware of the benefits of waste heat power generation, hold a positive attitude towards the development of waste heat power generation project. But limited to the large investment, complex technology, the current waste heat power generation project in China is mainly used for the strength of the cement industry.

As of 2011, approximately 700 cement production line is equipped with a waste heat power generation project, more than the number of new dry cement production line 50%, all the waste heat power generation project in 2/3 concentration in the cement industry. But clearly regulated in the new "cement industry access conditions" at the end of 2010, the Ministry issued on the new dry cement clinker, an annual production capacity of more than 900 kg per person provinces, in principle should not approve any new expansion (clinker cement production line project), the new cement clinker production line must be in strict accordance with the "implementation of the same or reduction out" principle.

With the implementation of the new "access conditions", cement new projects substantially reduced, waste heat power generation of cement projects supporting the construction of space will become increasingly smaller.

In this case, the development of waste heat power generation in the cement industry has been difficult to continue, waste heat power generation into the "cement" era, the future waste heat power generation must find a new way out. The market present situation, based on the future development of waste heat power generation, mainly focus on the following aspects:

First, continue ploughing in the cement industry market. Effects of cement kiln waste heat power generation in the energy saving has been widely recognized in the industry, there is no cement production line supporting waste heat power generation in the future will be the construction, the future still have space available for deep excavation. At the same time, an early batch of cement kiln waste heat power generation project in both technology and equipment level in the future have a renewed demand.

Secondly, to enter the iron and steel, metallurgy industry. Future waste heat power generation enterprises must find a new development direction, steel and metallurgical industry with its special status of the industry, is likely to become the new space for the development of waste heat power generation project.

In the steel industry, iron and steel industry energy consumption accounts for about 15% of the total energy consumption of national industry, the waste heat is rich in resources, energy saving space. According to statistics, the total waste of China's large and medium-sized enterprises have accounted for about 37% of the energy consumption of per ton steel, waste heat resources very considerable. This provided a foundation for the implementation of waste heat power generation project.

At present, the construction of iron and steel industry waste heat power generation project is far lower than that of the cement industry, the future of this piece of the market will be considerable.

In addition, to business model innovation to open up new market. The waste heat generating initial project investment cost is higher, many enterprises want to project, but eventually because of capital and technology is not a. Faced with this situation, the domestic some professional energy Service Corporation use of contract energy management to invest in waste heat power generation, namely the energy company invested and procurement of the required equipment, technology to project construction waste heat power generation project for the enterprise, produce efficiency recovery of investment in the mode of benefit. This model is to solve the enterprise lack of funds, technical problems, also makes the flue gas, exhaust, waste heat in waste to obtain the reasonable use, energy company funds to obtain reasonable operation. So, this win-win cooperation is being more and more widely used in waste heat power generation industry.

Facing the market opportunities in the future a considerable, waste heat power generation enterprises should do some what kind of preparation to talent showing itself in the competition in the future, become a dark horse?

On the one hand, to do practical business now, the energy savings. While the future of the iron and steel, metallurgy industry, the prospects are very broad, but the technology penetration is the need of time. The cement industry has gone through such a time in an accumulation of waste heat power generation, now the iron and steel, metallurgy industry is the same as the original cement industry, still need a process of cognition, recognized for waste heat power generation. Therefore, in the current market conditions, to the old cement based business, seek the development in a stable basis.

On the other hand, enterprises need to actively develop, improve the technical level. The technology and equipment of cement kiln waste heat power generation is relatively mature, have reached the international advanced level. But if applied to the iron and steel industry, according to the different heat sources, heat quality, flue gas composition still need a lot of transformation according to the specific situation. In order to seek business development, it is necessary to understand the main production process related industry, good technical reserves, actively preparing to cope with the challenge of the market.
