Biomass - Steam Turbine
Turbines for Biomass-Fired Power Generation and District Heating & Cooling Applications
Siemens turbine generator sets have been deployed in over 93 biomass fueled plants in the past decade with an outstanding record of applicability and reliability. Each turbine, along with its customer-specified features, is built to meet specific demands. These flexible machines can even optimize electric output in plants which have steam parameters affected by inconsistent feedstock moisture content. This is possible by integrating industry-leading steam cycle technology.
Steam turbines from 75 kW up to 250 MW
Whereas in Europe, due to subsidiary regulations, typically steam turbines up to 40 MW are used, other regions prefer a power output up to 120 MW. The Siemens industrial steam turbine portfolio can be used with any biomass boiler to generate power from 75 kW up to more than 250 MW. The Siemens team of experts will help select a turbine that meets application requirements while maximizing the investment’s value. Siemens can also supply your steam turbine with auxiliary equipment such as driven machinery (generator, compressor, or pump), a condenser system, monitoring and control systems, power transmission equipment and more.
Reheat Improves Efficiency
Turbines with reheat can improve overall plant efficiency by up to 3%, further mitigating the release of harmful emissions by burning less fuel. With the Siemens reheat package, live steam is run through a high pressure (HP) turbine, sent back to the steam generator to increase steam temperature, then run through a low pressure (LP) turbine. Raising the temperature of steam that is going from a high to a low pressure turbine allows for greater output using the same amount of fuel. There is also less steam going directly to the condenser, therefore requiring a smaller cooling system. Geared single-casing reheat solutions up to 60 MW are also available in the Siemens portfolio.
Combined Heat and Power
Combined heat and power generation, also known as cogeneration, is used for many different purposes. Harnessing heat created by power generation increases plant outputs, lessens fuel consumption, and creates another valuable commodity which can improve plant economics. Whatever the application of a cogeneration system, efficient conversion of waste heat into a commercial resource is a critical necessity. All Siemens turbines can employ extractions, bleeds, and other provisions to meet the customer specifications.
