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)

Innovative and flexible HRSG solutions

Siemens Heat Transfer Technology (hereafter Siemens) is a reputable 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 kind 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 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’ 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.
