The Spilling steam engine: the only one of its kind in the world.The Spilling steam engine combines the thermodynamic advantages of a filling-controlled steam reciprocating engine with the design features of the modern diesel engine. A unique construction worldwide making the engine a robust and variable power generator.
The advantages of the Spilling steam engine are particularly significant in heat-driven back-pressure cycles or with varying steam flows .That makes it ideal for use in plants with smaller to medium outputs, e. g. in
- combined heat power plants (CHP)
- smaller plants that produce electricity from biomass from approx. 2 MW fuel input
- waste heat generation units from approx. 2.5 t/h steam mass flow
- waste incineration plants and thermal afterburning units
The Spilling steam engine is also optimal in combination with saturated steam boilers, as well as steam generators with moderate live steam pressures and temperatures. Here the modular design principle of the reciprocating engine permits the flexible adjustment of the expander to suit a wide range of customer requirements.
Engineered as a single or multi-stage unit, Spilling steam engines can also be adapted optimally to various steam pressure differences. Furthermore, the possibility of separately controlling individual cylinder groups of the engine means that different process steam requirements can be handled using only a single expansion engine.
The outstanding partial load performance of the Spilling steam engine is achieved by the Spilling filling-regulation. This realises the operation over a wide range almost without pressure losses and so guarantees constant efficiency to large extent.
