Title:
EXHAUST GAS FLOW RECTIFICATION STRUCTURE, EXHAUST HEAT RECOVERY BOILER WITH THIS RECTIFICATION STRUCTURE AND RECTIFICATION METHOD
Document Type and Number:
Japanese Patent JP2015175525
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an exhaust gas rectification structure capable of reducing load of exhaust gas, an exhaust heat recovery boiler with this rectification structure and a rectification method.SOLUTION: This invention relates to an exhaust gas rectification structure in which exhaust gas from a gas turbine 1 is rectified by a rectifier 8 and guided to a group 7 of heat transfer pipes of an exhaust heat recovery boiler 2. The rectifier 8 has a smaller section than that of an exhaust gas flow passage 6 at its installation position and arranged at a position where at least maximum flow speed portion of the exhaust gas flowing at a section of the exhaust gas flow passage 6 at the arranged position is rectified. It is preferable that the rectifier 8 is arranged at a position where its center becomes the maximum flow speed portion of the exhaust gas.
