Case Introduction
Heater for the heating network
There are two types of district‑heating feedwater heaters: standard district‑heating heaters and peak‑load district‑heating heaters. These heaters are used in power plants to heat the water supplied to the district heating network. The heating steam is either extracted from a higher‑pressure turbine stage or generated by superheated steam drawn from the boiler, which is then desuperheated and depressurized before being used as the heat source to raise the district‑heating water to the required supply temperature.
The primary district‑heating heater operates continuously throughout the heating season and can meet the vast majority of water‑temperature requirements. During the coldest periods of winter, when higher supply temperatures are needed, the water exiting the primary heater is routed to a second heater connected in series, known as the peak‑load district‑heating heater.
High-pressure heater
Product Type: Horizontal, Vertical
Heat exchanger tube type and material: U‑bend carbon steel tubes, stainless steel tubes, alloy tubes.
Water chamber structural configuration: large opening self-sealing, hemispherical + small opening self-sealing.
Shell-side configuration: single-section (condensation section), two-section (superheated steam cooling section and condensation section), three-section (superheated steam cooling section, condensation section, and condensate cooling section).
Key technologies: The heat exchange tubes are joined to the tube sheet by a combination of strength welding and hydraulic expansion; the water inlet of the heat exchanger is equipped with flow‑distribution plates and stainless‑steel wear‑resistant sleeves.
Low-pressure heater
Product Type: Horizontal, Vertical
Heat exchanger tube types and materials: U‑bend stainless steel tubes, copper tubes, carbon steel tubes.
Water chamber configuration: cylindrical short section with elliptical end caps.
Connection method between the water chamber and the shell: flanged and bolted connection, or all-welded type.
Shell-side configuration: single-section (condensation section), two-section (superheated steam cooling section and condensation section), three-section (superheated steam cooling section, condensation section, and condensate cooling section)
