2009/6/11 · The plug extension 44 has a diameter 46 smaller than the original inner diameter 25 of the boiler tube stub 22. The length of the plug body 47 is longer than the removal length 36. As shown in FIG. 5, in order to remove the remaining boiler tube stub 32, the plug 40 is inserted into the shell 35 of the boiler tube stub 32, plug extension 44 first.
2020/3/17 · Decoking is the process of removing coke/scale build up from the process tubes of fired heaters and boilers. Internal cleaning of heater tubes can be done in several ways; chemical cleaning, steam-air decoking, in-line spalling and mechanical pigging are the most common. The effectiveness of each method varies.
In our patented process, the ammonia is recovered from the effluent and can be re-injected into the post-combustion chamber. The Main Advantages of the HZI SNCR Process: Low process investment and minimal infrastructure costs thanks to simple process technology and integration of the process in the post-combustion chamber of the boiler
For example the boiler is a tower boiler, but also other types of boilers are possible, such as 2-pass boilers. BACKGROUND In order to erect a boiler, traditionally a main structure (main steel structure) is installed and then all the boiler components are sequentially installed one-by-one on and around the main structure.
