Subcritical steam injection boiler

Since 1986, the (General Machinery Plant) Sanjack Petro’s former has obtained the qualification for manufacturing Class I and II pressure vessels.

Now the SANJACK ‘s special equipment has the national A2 level (Ⅰ, Ⅱ, Ⅲ) pressure vessel manufacturing qualification; D-level pressure vessel design qualification; A-level boiler manufacturing, installation, alteration, repair & maintenance qualification; American Society of Mechanical Engineers ( ASME) U and S stamp qualifications.

Subcritical steam injection boiler

The working fluid (water) pressure in the boiler is lower than the critical pressure and temperature : 22.12MPa 374.15 ℃ is called the subcritical boiler.

 

Typical subcritical steam injection boiler parameters:

The technical parameters of the boiler (take 11.5t/h subcritical boiler as an example):

Rated evaporation: 11.5t/h

Rated working pressure: 21MPa

Rated working temperature: 370℃

Operating steam dryness: 70~85%

Fuel: crude oil/natural gas

Boiler thermal efficiency: ≥91% (fuel oil)/92% (fuel gas)

Operating exhaust temperature: 170~200℃ (fuel oil)/110~140 ℃ (gas)

 

 

2 sets SJYZG 15-21-D boilers provide steam injection services for Sudan’s PE oilfield, with a cumulative gas injection of 30,000 cubic meters;
