To meet the demands of industry steam by the chemical industrial park nearby and solve the problem of high coal consumption

transformation on four 215 MW pure condensation units was conducted

and the external thermal network construction of this power plant was performed.Several countermeasures were taken

including regulating the extraction steam pressure

reforming the desuperheating water system

using high-pressure bypass as steam emergency supplement

placing a large thermal consumption user at the end of the heat supply network

and so on.Thus

the problems of safety

reliability

and economy were solved.After the retrofitting

the comprehensive energy utilization efficiency was enhanced

and the dramatic energy conservation and emission reduction was achieved.
