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 during load changes or by simply utilizing one of our diverter bypass stack systems.  

Heat Recovery Steam Generators (HRSGs)

Innovative and flexible HRSG solutions

Siemens Energy Heat Transfer Technology the leading OEM HRSG supplier, previously operating under the NEM brand name. We have provided the boilers behind many gas turbines, varying in size from 10 MW up to the largest machines, and for all kinds of fuels and applications. We offer a wide variety of boiler designs in order to be able to meet your specific requirements, focusing on the lowest total installed and/or operational costs. Since we can supply both horizontal and vertical boilers, we can optimize the boiler configuration to the smallest possible plot space available.

The benefit of design: fitting your purpose

Delivery concepts and site construction
We can supply our HRSGs in all kinds of prefabricated concepts, which enable you to optimize the total installed costs. They can be delivered in the form of small parts due to transport limitations, or even complete pre-erected units (‘plug & play’ design) in order to minimize construction site costs/risks, whether for onshore or offshore applications.

Fast Start & Cycling Operations
Siemens Energy is a worldwide provider of two types of Fast Start HRSG technologies: Benson® and DrumPlus™. Siemens’ HRSG fast start solutions offer a quick response to power demand, while maintaining the lifetime of any HRSG. This ability is of special importance in so-called spot markets and locations where the daily fluctuation in power is aggravated by power fluctuations of renewables. Siemens Energy fast start solutions allow unrestricted gas turbine ramp-up which results in remarkable flexibility, reduced start-up costs, quick delivery to the grid and significantly lower CO and NOx emissions during start-up.

Heat ReCycle solutions

The value of water can often not be expressed in price, especially in regions where water is a scarce asset. Learn more about Heat ReCycle in our on-demand webinar.

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.
