Smoke baffle arrangement structure of secondary reheating boiler and reheating steam temperature control method

The invention discloses a flue gas baffle arrangement structure of a secondary reheating boiler and a reheating steam temperature control method, a tail flue of the secondary reheating boiler is divided into three flues which are mutually independent and parallel, namely a primary low reheating flue, a secondary low reheating flue and a low passing flue; a primary low reheat flue baffle is arranged at the outlet of the primary low reheat flue, and a secondary low reheat flue baffle is arranged at the outlet of the secondary low reheat flue; the primary low re-flue and the secondary low re-flue converge at the outlet to form a convergent flue, and a low re-main flue gas baffle is arranged at the outlet of the convergent flue at the downstream of the primary low re-flue baffle and the secondary low re-flue baffle; and a low-passing flue gas baffle is arranged at the outlet of the low-passing flue. According to the invention, the low remain flue gas baffle is additionally arranged, so that the opening of the low
