Industrial Boiler Reheater and superheater with water spray system Chinese qualified manufacturer
Specification
1. Superheaters Coils are the most critical Boiler Component of the modern day Thermal Power Plant and are subject to very high metal temperatures.
2. In fact the capacity of the Superheater to work without failure at higher Temperatures is what determines the boilers Capacity and it effects improvement in economy by reducing Steam Consumption of the Steam Turbine.
3. We have fabricated thousands of Superheaters - Radiant, Pendant, Final, Fluidized Bed types, Reheaters for all kinds of Boilers having Complicated very close and Compact Shapes with tube sizes ranging from 32mm OD to 76.2mm OD and thickness from 3mm of 12mm in all types of Boiler Quality Steel Grades ranging from Carbon to Alloys and Stainless Steel for metal temperature ranging up 650 C and for Boilers of 10 to 500 MW Capacity.
Reheater Function
1. Therefore the number of reheat stages can not be many as the pressure drop will reduce efficiency of thermal cycle.The steam pipes and reheater coils are to be so designed to limit the drop to 2–3%.
2. The control valves in reheat steam path is not desirable.Systems using HP LP bypass require these valves to control steam flow during bypass operation.
3. The efficiency of the Reheat cycle can be improved by increasing the pressure and temperature of steam entering into the turbine. As the initial pressure increases the expansion ratio of the turbine also increases and the steam becomes quite wet at the end of expansion.
Performance feature
1. The custom of boiler
With a mature technical team, Dehai boiler can be designed according to the smoke and steam parameters provided by users to achieve the best effect.
2. Low resistance
The boiler body adopts the design of uniform flow rate and low flow rate, and the body resistance is less than 900Pa at the design working condition, which is conducive to the combination with other equipment and to reduce the power consumption of the system.
3. long life
It has long service life, simple operation and maintenance, economic safety and reliability. It is fully applicable to float glass furnace production line using heavy oil or natural gas fuel.
4. Reliably Sealing
The light fender all-welded furnace wall structure is adopted, and the connection between the fender and the steel frame is of flexible sealing structure, so as to ensure that the joint between the fender and the steel frame is not diswelded due to thermal expansion during boiler operation.The whole welded sealing structure of the pipe bundle through the wall of the guard plate furnace reduces the air leakage of the boiler.
Differences
| 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. |
