Heat Transfer Technology

An efficiency boost

 

Steam is an essential element in the energy supply system. As a primary energy source, it fulfills many important functions, whether it’s used to operate a turbine, as process steam for use in industry, or for district heating.

 

Therefore, heat recovery steam generators (HRSG) are important components of many power plants: They substantially increase a plant’s overall efficiency, and help to minimize the costs of fuel. You also benefit from greater flexibility when operating at part load or during load changes.

Heat Recovery Steam Generators (HRSGs)

Natural Circulation HRSGs

Robust drum technology also makes it possible to use steam for basic applications, such as electricity generation or supplying heat. An innovative drum design improves flexibility and efficiency in power plant operation.

 

Our HRSGs from 10 MW to the largest gas turbines offer lower installation costs, less site risks, and, potentially, and earlier commercial operation for the entire plant. How do we accomplish this? Through a higher degree of standardization of pressure part modules.

The benefit of design: Cold-casing and counter flow evaporator

Horizontal natural circulation: Cold-casing design

Designed for natural circulation of the water/steam mixture in the evaporator tubes, our horizontal HRSG uses a cold-casing design. Completely insulated and lined with sheeting, cold-casing design allows you to quickly start-up your gas turbine. Additionally, it enables you to use higher gas temperatures associated with modern gas turbines.


Vertical natural circulation: ‘Counter flow’ evaporator design
Our HRSG’s unrivaled, state-of-the-art patented 'counter flow' evaporator design offers:
- Free expansion of headers and tubes
- Readily accessible headers and bends for inspection
- Stress-free repair and maintenance
- Easy on-site construction

 

Waste Heat Recovery Units (WHRU)

Harnessing energy to the maximum

The WHRU offers an efficient method of recovering thermal energy from the waste heat of gas turbine exhaust gases. This method allows a significant increase in the efficiency of the turbine train, and a decrease in both fuel demand and pollution. We are able to supply the entire scope for your gas turbine train, bringing the total number of parties required for project realization back to only one.
The standardized design fits every type of gas turbine, ranging from 10 to 70 MW. It is therefore in perfect harmony with, but not limited to, the existing Siemens gas turbine portfolio.
