Steam Cogeneration is high temperature HVAC which requires high usage and demand in order to be practical. Steam turbine cogeneration is only suited to sites requiring 1 megawatt and above power demands.
At Helec we are experienced at providing low temperature (sub 90 degrees) HVAC systems which run up to 1 megawatt but at low temperature. We can provide supporting systems to steam turbine cogeneration systems.
For most commercial uses gas fired CHP systems are more practical – you can view the full range of gas fired CHP systems by visiting this link.
How Steam Cogeneration Works
A steam generated power station is a power plant where water after its heated turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed and recycled back in to the same place where it was originally heated.
This cycle is known as a Rankine cycle named after the engineer William Rankine, a civil engineer who developed the theory and process.
Almost all large scale steam cogenerating power plants today still adopt this steam cycle in order to operate the turbines efficiently and provide high levels of constant electrical power generation.
The capital cost to build and the size of plant required demands a constant load 24/7 for viability and financial advantages but the main advantage for this type of cogeneration is the long plant life for the turbines due to low wear and tear.
The main difference in the design of thermal power stations is due to the different resources generally used to heat the water. The fossil fuels mostly used with steam cogeneration systems are Coal, Oil and Natural Gas.
