Along with the process of urbanization in our country, more and more cities have suffered from the difficulties of "garbage besieging the city" and the other side also faces the dilemma of "no land to be buried". As a harmless treatment method that highly saves land resources, the prospects for waste incineration and power generation are broad. At the same time, controversial waste incineration is bringing an investment feast for compressor companies. The most representative one is the screw-type steam expansion generator set developed by Kaishan Group.
The traditional waste disposal methods are mainly sanitary landfills and high-temperature composting, and require large amounts of land to be occupied, which can easily lead to environmental pollution. With the acceleration of urbanization, the limited land resources of large and medium-sized cities have become increasingly "stretched." However, it is an indisputable fact that garbage needs to be disposed of. The emergence of incineration power generation has given garbage a new “magic powerâ€.
According to Feng Xiangpeng, deputy general manager of Shougang Biomass Energy Technology Co., Ltd., the burning of one ton of garbage can generate 360 ​​kwh. Calculated at an annual processing volume of 1 million tons, it can generate 360 ​​million kwh electricity per year and output 280 million kwh. Waste heat from burning garbage can also be heated in the factory heating pipes, converted into hot water and sent to nearby residential buildings. The slag generated after incineration of garbage only accounts for about 20% of the weight of garbage before incineration and can be used for the production of cement.
The industry believes that with the operation of waste incineration power plants, the landfill-based treatment model is quietly changing, and compressor companies will usher in a new investment feast.
Shi Yang, Chief Engineer of the China City Environmental Health Association Technical Consultation Center, told the media that during the 12th Five-Year Plan period, China will add about 400,000 tons/day of processing capacity and about 140 billion yuan of additional investment. China’s total investment in waste disposal will reach 260 billion yuan. According to industry sources, among the 260 billion yuan in cakes, over 100 billion yuan will be cut to waste to generate electricity.
It is understood that, at present, garbage incineration projects have been launched all over the country, but all have been promoted in a low-key manner. There are 20 cities in Shandong Province and Zhejiang Province respectively, 17 in Fujian Province, and 14 in Jiangsu Province and 13 in Guangdong Province.
With the low-key advancement of waste incineration, relevant industry pioneers have also seized business opportunities. Under the leadership of Dr. Tang Yan, General Manager of Kaishan Compressor Co., Ltd., after one year of research and efforts, the ORC screw expansion generator was successfully launched in August 2013, and Kaishan Compressor Co., Ltd. was successfully developed in 2014. Screw type steam expansion generator set. Test data shows that various technical indicators have reached the design requirements.
According to reports, the application and scope of screw expansion power generation technology is very extensive. It can be used to generate power from waste steam without pressure, low-temperature hot water at 80 degrees or above, thermal fluid power generation from chemical process, engine exhaust, and liner cooling water. Low-temperature flue gas power generation, cold-source power generation in the LNG gasification process and the use of any temperature difference, differential pressure power generation, and geothermal energy, solar thermal power generation and biomass power generation and other new energy fields.
The advent of screw-type steam expansion generators will completely replace the medium and small-sized steam turbines. It is foreseeable that, in the future, saturated steam at flow rates of several tens of tons per hour will no longer use steam turbines for waste heat recovery and power generation. We call this product " Subversive great products" is not an exaggeration.
