High pressure steam generators for electric power generation with max(x)imum plant efficiency



maxxtec is worldwide one of the leading suppliers of heat recovery systems for the recuperation of heat from exhaust gases from biomass firing systems, thermal incineration plants, gas turbines and diesel motors. These plants are increasingly more used for electric power generation.


Economic and ecological considerations require optimum plant design with highest cost-effectiveness and optimum plant efficiency. To satisfy all these requirements maxxtec offers high pressure steam generators with water tube steam boilers in modular design for 65bar and 465 °C.


Compared to large scale power stations, the decentral use of such plants and the modular design offer considerable advantages such as:


  • simple fuel supply and even heat recuperation from existing energy streams
  • the utilization of waste heat for local use or for district heating systems, resulting in low transfer losses
  • redundancy and a high control range when using several modules in parallel
  • various countries pay high feed-in tariffs when using renewable energy sources, especially with natural biomass
  • the use of standardized plant components and serial products


The special maxxtec design allows a complete preassembly of the water tube steam boiler in our works. In this way the installation costs on site are
considerably lower compared to conventional water tube steam boilers.



The generously sized plant components allow constant steam parameters and there will be no drop formation, not even at fast load fluctuations.


The heating surface cleaning system which we developed, allows cleaning intervals of up to 8000 hours and an availability of >92% when using natural fuels. Multi-stage condensation turbines with steam bypass station and heat recuperation of the exhaust gases with economizers and air pre-heaters offer highest overall-efficiency of the plant. In this way maximum efficiency of the entire plant is ensured.


Our high pressure steam heat recuperation plants are available in 2 sizes. Electric capacities of 1,8 MWe, 2,5 MWe, 3,6MWe, 4,3 MWe and 5 MWe can be realized, when using max. 2 modules. Depending on the client's wishes maxxtec delivers the entire plant from the feed water pre-heater to the steam turbine, complete control- and monitoring systems, water treatment and condenser, commissioning and start-up included.
