Problems solved by technology

[0009] In short, if the primary reheater and the secondary reheater are connected in series to stabilize the blowpipe, the steam at the inlet of the secondary reheat system is prone to overheating and the blowpipe coefficient is too large; the existing solutions will reduce the blowpipe coefficient of the superheater, and the operation adjustment extremely difficult

Abstract

The invention provides a secondary reheating boiler pressure stabilizing steam blowpipe system and method. The secondary reheating boiler pressure stabilizing steam blowpipe system comprises a separator, a superheater, a reheating system, a target plate device and a silencer which are connected in sequence, and the reheating system comprises a primary reheater system and a secondary reheater system; and the primary reheater system and the secondary reheater system are connected to the output end of the superheater in parallel. The pressure stabilizing blowpipe system is arranged to be of a parallel pressure stabilizing blowpipe system structure, a primary reheater and a secondary reheater are connected with a pressure stabilizing blowpipe in parallel, the problems that steam at an inlet ofa secondary reheating system is prone to being overheated, the blowpipe coefficient is large, and the blowpipe coefficient of a low-temperature superheater is small are solved, and obstacles are eliminated by adopting the pressure stabilizing blowpipe on a secondary reheating boiler.

Description

technical field [0001] The present disclosure relates to the relevant technical field of steam blowing pipes of double reheating units, and specifically relates to a pressure-stabilized steam blowing system and method of double reheating boilers. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The double reheat unit has higher power generation efficiency and lower coal consumption than the single reheat unit, which is the development direction of coal-fired units. Boiler steam blowing is an important commissioning process before a new thermal power unit is put into operation. Generally, there are two methods of boiler blowing: the pressure-stabilizing blowing method and the pressure-reducing blowing method. The pressure-reducing blowing method is a very bad abnormal operating condition for the boiler. The rate of change and range of ch...
