Hot water circulation pump for CSP Steam System

Solar Power is the renewable Power in now days and would play more and more important roles in the Energy Power Industry.
We could offer the product with higher pressure (up to 30Mpa) and hot water condition (TMEP up to 330’C) with no Seal less risk, this is based on the Technology that applied to Super Critical Power Plants across the whole world with more than 50-60years technology

Hot water circulation pump for CSP Steam System

Vertical or Horizontal layout , suspended in piping system
Pump case and stator case are designed to be one pressure vessel with no pressure difference, to have one shaft and make sure there is no leakage, no mechanical seal.
Free of conventional mechanical sealing, to ensure completely free of leakage. Widely used in extremely high temperature and high-pressure situation, proper prove to the most critical requirement to operation security.

Applications

Hot water circulation pump for HRSG —Heat Recovery Steam Generator

Iron and steel metallurgy industry
Biomass waste power generation
Gas Power
Coking furnace
Glass Furnace

Petrochemical catalytic Unit— TEMP adjustment for Reaction

Chemical: Sulfuric acid production unit, medium and heavy oil gasified for synthetic ammonia production (TEMP@Suction 1350’C,Pressure 3.2-4.0Mpa U type Boiler)
Petrochemical: Petroleum cracking unit , Catalytic cracking, Pyrolysis of petroleum hydrocarbons to ethylene requires high heat transfer rate boilers, such as elliptical collector tube sheet waste heat boiler

Forced Heat Recovery Boiler

Forced Heat Recovery circulation boiler, they have to use circulation pump to build up this steam circle

——- HRSG

Applications

metallurgy
Steel
Gas Power
Coking

Chemical Reaction Recovery

Catalytic cracking waste heat boiler is used in the catalytic cracking and pyrolysis unit of heavy oil in petrochemical system refinery.

During operation, the high-temperature flue gas energy of the catalytic device is recovered for the saturated steam generated by the oil slurry steam generator and external heat collector in the super heater and the medium pressure saturated steam produced by ourselves to form the medium temperature and medium pressure superheated steam device

For the exothermic reaction of synthetic ammonia, the temperature shall be properly absorbed to prevent the temperature in the tower from being too high.
