摘要
The invention relates to a two-stage reheater in a two pass tangential fired boiler to maintain steam temperature imbalance between the right and left leads of reheater outlet within 10�C, comprising : a reheater front section having left side and right side inlet and outlet header; a reheater rear section having left side and right side inlet and outlet header; the reheater front section outlet header sustaining temperature imbalance due to gas side unbalance when steam from a high pressure turbine is first heated; a plurality of criss cross links provided between the reheater front section and the rear section; and a plurality of Siamese headers disposed at the outlet of the reheater rear section such that alternative assemblies of the tubes of reheater rear section are connected to said Siamese headers.
