Thermal power generation plant is the most conventional source of electric power. Conventional plants produce electricity by burning fossil fuels, such as coal, in order to have pressurized high temperature steam and to use it to rotate a turbine, with electricity production as result. Biomass is biological material widely used as an alternative energy source in thermal power generation. Handling those kind of materials in a complex power plant imposes to design a system with exceptional reliability in order to avoid any kind of shutdown for tens of years. STM provides a complete engineering including specific back-up solutions, limited maintenance devices, best-in-class components manufacturers.
