Finned Tube Heat Exchanger with Waste Heat to Generate Steam for Power or Heat Generation

Combining finned tube heat exchangers to generate steam from waste heat for power or heat generation is an effective way to improve energy efficiency.

In such systems, finned tube heat exchangers are used to recover heat from high temperature exhaust gases or other hot fluids. The recovered heat is used to heat water to produce steam. The steam can be used to drive a turbine to generate electricity or can be used directly for industrial heating or heating.

Key Components and Processes

Finned Tube Heat Exchanger:

By installing fins on the outside of the tube wall, the heat transfer surface area is increased and the heat exchange efficiency is improved.

High-temperature exhaust gases or hot fluids flow through the finned tube heat exchanger and transfer heat to the water inside the tubes.

Boiler system:

The recovered heat heats the water to the boiling point and produces steam.

The steam is piped to different applications.

Steam Turbine (Power Generation):

Steam drives a turbine, which drives a generator to produce electricity.

This can be used for self-generation or integrated into the grid.

Heating Systems:

Steam is used for heating in industrial processes or for district heating.

It can effectively reduce the need to rely on conventional fossil fuels for heating.

System Advantages

Energy efficiency:

By recycling waste heat, the overall energy efficiency of the system is improved.

Simultaneous dual function of power generation and heating reduces energy wastage.

Reduced operating costs:

Make full use of the waste heat produced by the generator set, reducing the need for external energy.

Reduce the cost of energy purchase and fuel consumption.

Environmentally friendly:

Reduces exhaust emissions and lowers carbon footprint through efficient use of waste heat.

Contributes to sustainable development goals.

Application Scenarios

Industrial facilities: In manufacturing and chemical plants to recover heat from high temperature process gases.

Power Plants: In gas turbine or internal combustion engine power plants to recover heat from exhaust gases for steam generation.
