Abstract
Turbine shrouds for turbine systems are disclosed. The turbine shrouds may include a forward end, an aft end, a first and second side, an outer surface facing a cooling chamber formed between the body and the turbine casing, and an inner surface facing a hot gas flow path for the turbine system. The turbine shroud may also include at least one collection plenum extending within the body between the forward end and the aft end. Additionally, the turbine shroud may include set of cooling passage(s) extending within the body. Each of the cooling passages of the set of cooling passage(s) may include an inlet portion in fluid communication with the cooling chamber, an outlet portion in fluid communication with the at least one collection plenum, and an intermediate portion fluidly coupling the inlet portion and the outlet portion.
