Steam Boiler Spare Parts Superheater And Reheater for Thermal Power Plant Boiler
Product Description of Boiler Superheater and Reheater
| 1 | Boiler economizers reuse exhausted flue gas to pre-heat the feedwater entering the boiler. |
| 2 | Essentially a mini-heat exchanger, economizers improve boiler performance while increasing fuel efficiency. |
| 3 | By rapidly increasing feedwater temperature through captured flue gas, economizers also provide a significant improvement in steam generation and response time. |
Technical specifications of Boiler Superheater and Reheater
Material Structure
Consists of a serious of spiral fin tubes, the headers of inlet and outlet, bend, frame and other auxiliaries.
Structure Arrangement
In line / staggered arrangement.
Characteristics of Boiler Superheater and Reheater
| 1 | This type of economizer can largely develop the heat exchanging area than the bare economizer to add the heat transfer area, reduce the volume, compact structure and reduce the number of elbow and welding to make less leakage and add the heat transfer efficiency. |
| 2 | Not easy to collect dust and the fume pass through the fin tube to form the boundary layer to occur the vortex to make less chance for the fly ash particle to touch the tube wall. |
| 3 | Widely temperature range, high pressure limit. |
| 4 | Durable strong impact, reliable operation. |
| 5 | less fume resistance, reduced abrasion and long working life. |
| 6 | Beautiful appearance, simple fabrication process. |
| 7 | Diverse layout. |
| 8 | Ease of installation, ease of construction. |
| 9 | A wide range of working pressure . |
Manufacturing and acceptance criteria of Boiler Superheater and Reheater
| 1 | JB/T6512 "boiler with a high-frequency resistance welding spiral fin tube manufacturing technology conditions" |
| 2 | HG/T3181 "high-frequency resistance welding spiral fin tube" |
| 3 | JB/T6511 "spiral finned tube test technical conditions." |
