Usage of Temperature & Pressure Decreasing Equipment

Differenet types of  Temperature & Pressure Decreasing Equipment, produced in our factory, equipped with corresponding automatic industrial instrument panel.(i,e heat control cabinet) absorb in primary steaming pressure P1 and Temperature T1 coming from power Station, indutry boiler and heat and power plant to make the secondary steaming pressure P2 and temperatuer T2 up to the desired demand of producing technology. Temperature & Pressure Decreasing Equipment is widely applied to such industry as power station, light textile & petrochemistry.

Temperature & Pressure Decreasing equipment can be classified into: temperature & Pressure Decreasing equipment according to primary steaming pressure P1 & Temperature T1 for high temperature & High Pressure,

Temperature & Pressure Decreasing Equipment for Sub-high pressure,

Temperature & Pressure Decreasing Equipment for Middle Temperature Decreasing, pressure  decreasing,

Temperature & Pressure Decreasing Equipment Model Classification

WY----(A)----(B) / (C)----(D) / (E)--- (F) / (G)

WY--------The code name of Temperature & Pressure Decreasing Equipment, Expressed by the first Chinese Phonetic Alphabet: "Wen" & "Ya"

A-------T/h   The Outlet Steaming Discharging Value

B------MPa   Inlet Steam Pressure

C------℃, Inlet Steam Temperature

D-----Mpa, Outlet Steaming Pressure Value

E------℃, Outlet Steaming Temperature

F------MPa, Water Supply ( Temperatue--decreasing water) pressure value.

G-----℃, Water Supply ( Temperature-Decreasing water ) temperature

For Example: WY80--3.82/450--0.98/260--8.0/104

It refers to a kind of temperature & pressure decreasing equipment with 80 T/h Outlet Steaming Discharge, 3.82 Mpa Inlet Steam Pressure, 450 ℃ Temperature, 0.98MPa outlet steam pressure, 260 ℃ temperature, 8.0 MPa Temperature decreasing & pressure of water supply, 104 ℃ temperature of water supply.
