Abstract
The invention discloses a tower-type boiler with a primary reheater and a secondary reheater. The boiler comprises a low temperature superheater and a high temperature superheater, and the process of a main steam system comprises the following steps: feed water enters a front flue economizer and a rear flue economizer (10) which are arranged in parallel, water from outlets of the economizers enters water cooled walls (1) from the lower part of a furnace; outlets of the water cooled walls are connected with a separator (19), and steam from an outlet of the separator enters the low temperature superheater and the high temperature superheater (31) sequentially. As seen from the direction of steam flowing from low temperature area to high temperature area at the steam side, the primary reheater sequentially comprises a primary reheating low temperature reheater (11) and a primary reheating high temperature reheater, the secondary reheater sequentially comprises a secondary reheating low temperature reheater (12) and a secondary reheating high temperature reheater, and the primary reheater and the secondary reheater are arranged in parallel in a vertical flue.
