The development trend of waste heat power generation is analyzed

With the increasingly mature skills of waste heat power generation, the state attaches importance to energy, supports energy conservation and emission reduction, and more and more enterprises that can use waste heat are aware of the benefits brought by waste heat power generation. Taking a positive attitude towards the development of waste heat power generation projects. However, limited to the project capital, complex skills, resulting in many companies want to project can ultimately because of capital skills did not succeed.

In view of this situation, many professional energy-saving service companies have emerged in China to use EMC (contract energy management) to fund waste heat power generation, that is, by the energy-saving company to invest capital and purchase the required equipment, skills to build waste heat power generation projects for enterprises, and recover the investment in the form of benefits after the project.

This form not only deals with the shortcomings of the lack of funds and skills of the enterprise, but also makes the flue gas, tail gas and waste heat of the usual waste be used reasonably. At the same time, it also makes the funds of energy-saving companies reasonable operation, and this win-win form of cooperation is becoming more and more popular in waste heat power generation projects.

Low temperature waste heat power generation organic working medium cycle power generation system is different from the traditional power generation system using water (steam) as the cycle working medium, the selection of organic working medium (such as R123, R245fa, R152a, chloroethane, propane, n-butane, isobutane, etc.) as the cycle working medium power generation system, because the organic working medium can be vaporized at a lower temperature to produce a higher pressure. Promote the turbine (turbine) to do work, so the organic working medium cycle power generation system can achieve useful power generation at the flue gas temperature of about 200℃ and the water temperature of about 80℃.
