• Superheating raises overall efficiency as well as avoids too much condensation in last stages of turbine which avoids blade erosion.
• The heat of combustion gases from furnace is utilised for removal of moisture from steam and to superheat the steam.
• Super-heaters ususlly have several tube circuits in parallel with one or more return bends,connected between headers.
• Heat from the hot gases to the vapour in the surperheater is transferred at high temperatures.
• Therefore promary section of superheater is arranged in counterflow and secondary section in parallel flow to reduce the temp. stressing of the tube wall.
Type | Advantages | Disadvantages | Supporting method |
Pendant-type | 1.Firm structural support | 1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom. |
supported from above |
Inverted-type | 1.Proper drainage of the condensed steam | 1. Lack the structural rigidity, especially in high speed gas flow. | Supported from below |
Horizontal -type | 1. Proper drainage 2. Good structural rigidity. |
1. They do not view the flam directly so they are mainly from the convective type. | Usually supported in the vertical gas ducts parallel to the main furnace. |
·For special cargos, such as overlength, overwidth, overheight and overweight cargos, we will choose frame boxes for easy handling.
·For regular goods, we prefer ordinary containers.
·After loading the goods, we will reinforce them in all aspects.
38 years experience in industry research, development and manufacturing with sufficient production capacity.
Quality Control
1. Impact test and Strength calculation report with applied materials information.
2. 100%NDT(non-destructive inspection) report of steel plate, tube and electrode
3. X-ray, γ-ray and liquid penetrant test inspection report (welding seam): to ensure the quality of the entire boiler
4. Hydraulic test report: ensure the standard working pressure and safety.
Q1: How long is the warranty period?
