ORC low -temperature waste heat power generation technology application direction

The ORC low -temperature waste heat power generation system can be widely used in industries such as steel, cement, petrochemical, electricity, metallurgy, glass, etc., 

which is of great significance to reduce energy consumption and environmental protection. 

ORC low -temperature waste heat power generation system available for low product (referring to energy with low conversion efficiency) mainly has the following forms:

1. Homobight. 

Recycling industrial heat can reduce industrial energy consumption and greenhouse gas emissions. 

Most industrial processes or flue gas discharged by power plants, the temperature is generally not higher than 400 ° C.

2. Geothermal. 

The geothermal power generation uses the water steam or thermal water as the source of the heat. 

The geothermal fields that have been investigated in my country are currently surveyed. Most of the geothermal water used is near the saturation state, and the temperature generally does not exceed 200 ° C.

3. Solar. 

The energy density of solar energy and the temperature of the heat source is not high. 

It is necessary to use an organic Langken -based circular heat power system based on thermal collection technology. After the heat collecting device, the temperature can reach 300 ° C. 

For example, collecting solar hot water with a flat plate collector as a driving heat source below 100 ° C, and using orc transparency to form a low -temperature solar heating power generation system, which can be used as a distributed energy source.

4. Biomass energy. 

Biomass energy is also one of the important driving sources of organic Langken cycle. 

Biomass energy power generation adopts an organic Langken cycle mainly due to the small hours in the unit size, and organic work quality has higher turbine efficiency. 

In addition, the organic Langken cycle is also used for cold energy recovery and other occasions of LNG (LNG).
