Steam turbine

The steam turbine is the most widespread technology currently used for electricity production from biomass; effective for  high capacity systems (> 1 MW electrical). Steam turbines leverage the Rankine Cycle and requires the implementation of high pressure steam boilers. This technology is mature and well mastered around the globe.

This electric generation solution is tailored for large industrial sites generating significant excess steam volumes; such that cogeneration becomes a means to regulate plant energy consumption. It is also the main technique used in large
nuclear or fossil fuel power plants to convert thermal heat energy to electricity.

Emispec acts as project engineer and/or project manager to implement turnkey steam turbine projects; for extractive or back pressure turbine types.

Steam turbine cogeneration  enables the use of multiple primary industrial waste products; such as wood waste in sawmills, or vegetable waste from agriculture.

The thermodynamic cycle of steam turbines is based on the  Rankine cycle. Using the heat generated by burning a fuel, it produces steam at high pressure into a boiler.  This steam is then directed to a turbine, which in itself relaxing, drives the turbine. Output of the turbine, the steam is condensed and reduced to the boiler, where the cycle begins again. In this cycle, the combustion is external: that is to say that there is no direct contact between the process fluid (steam) and the home. Thus the fuel does not require specific qualifity specifications and therefore any fuel can be used.
