Project Name: GUOHUA POWER Dingzhou Power plant Reconstruction Project

Company Name: PowerChina Hebei Electric Power Engineering Co., LTD

Project Description

Region Dingzhou City, Hebei Province, P.R. China
Dates 2020-2021
Scope The reconstruction project includes the expansion, transformation and optimization of the original heat supply network main station, the addition of 2 sets of 50 MW Condensing and back pressure turbine generator units, 2 sets of demisting mechanical cooling towers (6 groups), cooling water system and the related ancillary equipment, etc.
Project Specific

The original power plant had a limited space, while the new DN2000 pipe had to be set underground.

Current local company is able to design only DN1400 pipes in the normal project.

The buried pipe had to be placed under the road; the steel jacket pipe needs to be used to support the big surface load.

Big size steel jacket PUR pipe is the main challenge.

PASS software used PASS/START-PROF
How PASS software helped in the project execution

PASS/START-PROF has been used to model all pipes for this reconstruction project.

PASS/START-PROF strong buried pipe analysis ability offers the chance to analysis DN2000 PUR buried pipe.

Embedded ′Elements′ module used to check surface load helped to calculate a more accurate jacket and to adjust pipe thickness.

Results The project design is in its final stage; all pipes and equipment are being installing on site.
