Waste heat recovery power generation - Delor fan
Release time:2021-07-15   Browse:1546

In late autumn and early winter 2018, more than 70 containers were being loaded at the Chinese port of Dalian, bound for Myanmar, where a distributed power station was waiting for the shipment. Few know what role the equipment in these containers will play in the future. Perhaps the launch represents the opening of a global market that is almost impossible to assess, and the same equipment may enter all walks of life in the future, bringing tremendous impact and transformative changes to the global energy market.

This is a low-temperature waste heat generator with power of 90KW. The significant difference between its technology and the traditional power generation technology that takes water (steam) as circulating working medium is that it uses organic working medium (such as R123, isobutane, etc.) as circulating working medium to circulate instead of water (steam). Because the organic working medium can be gasified at a lower temperature to produce higher pressure and drive the expander to do work, the technology can make use of low-temperature waste heat (waste heat) resources (flue gas at about 200℃, hot water at about 130℃) to achieve valuable power generation.

What role do Delor fans play in thermal power generation?

Use of internal combustion engine, geothermal, chemical, natural gas and other produce more than 90 ℃ heat, the device can be 90 degrees per hour, annual output of 770000 degrees, RMB 580000, and can be used either as a direct interconnection DE style fan to save more than any other brand fan power 4.2 per hour, for more than 24 hours under a constant state of electricity generation 100.8 degrees, It saves employers 36,000 kilowatt-hours (about 27,000 yuan) per year! This shows that its economic value is great. As for energy consumption, Dele will save every penny! Equipment in the case of continuous waste heat supply, a steady stream of power generation, the key parameter of waste heat recovery is power generation efficiency, the key component of the whole equipment is the heat dissipation fan. The higher the energy efficiency of the fan, the greater the power generation of the equipment. After 7 days and nights of continuous exploration and testing, Dele fans finally cut through the way to achieve amazing ultra-high efficiency, efficiency is 20% higher than other brands in the same style! This figure is a key parameter for Myanmar's power generation projects, meaning that domestic brands have achieved the same performance as international high-end brands.

The fan is reliable for more than 5 years, and the spare parts are standardized and can be easily interchangeable.

China's waste heat resources still have a lot of space to use. At present, the United States leads the industry in the utilization of waste heat resources, with its utilization rate reaching 60%, Europe's 50%, and China's only 30%. The reason why the gap is so large and the utilization rate is so low is "a technical problem.
