Abstract
Official abstract text for this publication.
An auxiliary burner configured to heat exhaust gas on an upstream side of any one of heat exchangers, and a fuel supply system configured to supply fuel to the auxiliary burner. To avoid damage of a heat-transfer pipe by exhaust gas of high temperature, a reference value on which the restriction on the charging quantity to be supplied to the auxiliary burner is based is set, and the charging quantity of fuel to the auxiliary burner is restricted so as not to exceed a limit defined by the reference value.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heat recovery steam generator, comprising: a duct, in which an exhaust gas from a gas turbine is configured to flow; a superheater, an evaporator and an economizer installed in the duct along a flow direction of the exhaust gas; an auxiliary burner configured to heat the exhaust gas and provided at an upstream position in the flow direction of the exhaust gas relative to any one of the superheater, the evaporator, and the economizer; a fuel sup…
