Discussion on the installation rate of waste heat recovery unit in China

Most of the industrial energy consuming devices in China are operated in large quantities, and the sensible heat and latent heat cannot be reasonably utilized in their original design. Under the concept of vigorously promoting energy conservation and emission reduction and using green energy, the rough industrial development has gradually exposed its disadvantages in the past decades. A series of concepts such as high temperature waste heat, cooling medium waste heat, waste water waste heat, high temperature products and slag waste heat are coming out, which is the leading direction for the HVAC industry to help reduce consumption.

The total industrial waste heat resources account for 17% ~ 67% of the total fuel consumption in China, and the recyclable part accounts for 60% of the total waste heat. Under the background of vigorously promoting industrial energy conservation in the 12th Five Year Plan, the utilization of waste heat in high energy consuming industries is accelerating. The pressure of declining demand and profit space has also prompted industrial enterprises to start learning "tight days" and "turning waste into treasure" waste heat recovery device technology has been welcomed by enterprises.

"Industrial utilization efficiency is a weak link in China's development, and waste heat recovery unit is also quite different from developed countries. In fact, every little bit of our economy is very beneficial to the development of the industry and even the country. " "People have been talking about the crisis, and I think it's focused on two things: energy and resources," the industry said. China is facing great environmental pressure, many problems have exceeded the warning line. When it comes to waste heat recovery, thinking changes will change the outcome. " At present, the recovery rate of waste heat in the domestic market is 30% - 50%, and the cost of waste heat recovery and utilization projects is generally over 100 million yuan. The utilization rate of China's waste heat recovery unit is less than 20%, and it has reached 50% in the United States and other developed countries.

Taking coal as an example, 50% of China's coal is used for power generation, and a lot of waste air and exhaust air are wasted. This is an opportunity for the development of the whole waste heat recovery and utilization market. This part of wasted resources can be reused through waste heat recovery and utilization. With the energy conservation and emission reduction listed as the "hard index" to assess economic development, the utilization of waste heat and residual pressure by waste heat recovery plant manufacturers has been raised to the national strategic level with its considerable economic and social benefits.

With the acceleration of industrialization and urbanization in China, the government has made a strategic decision to build a resource-saving and environment-friendly society. Energy saving, emission reduction and comprehensive utilization of resources have become the common goal of governments and enterprises at all levels. More and more enterprises have joined the industry, and the increasingly mature waste heat recovery technology also provides ideas for solving waste heat utilization. Data shows that as of the first half of this year, there have been more than one thousand enterprises engaged in waste heat recovery.

It is worth noting that for these pioneers involved in the field of heat recovery, their preponderant advantages may make them take the lead in the market. "The process of waste heat recovery is like squeezing sugarcane juice. How much you can finally get depends on the number of times you" squeeze "and the level of technology."
