Must gas boilers use corrugated water tanks? How do I determine the number of ripples?
Thread Content
Boiler code requirement: In the structural design of boilers, it is necessary to ensure free expansion of the heated parts. 1. For fuel and gas boilers with a furnace chamber, without making any openings in the furnace chamber cylinder, it is only by using a corrugated furnace chamber to provide elasticity that it is possible to ensure free expansion of the furnace chamber cylinder at high temperatures and thereby reduce stress; this is understandable. 2. For a furnace chamber with corrugations, how is the number of corrugations determined? ? ? I am ignorant and do not know where I can find relevant information. 3. If there are many water tube holes or fire tube holes in the furnace chamber cylinder, is it still necessary to use a corrugated furnace chamber to provide elasticity? ? ? I seek an expert’s explanation. . . .
It’s not necessary to use a corrugated furnace chamber; it is mainly determined by the structure and strength
The furnace chamber expands; those with corrugations expand more than those that are flat, and those with dense corrugations expand more than those with sparse ones. There are no specific requirements regarding whether the furnace chamber should be straight or corrugated; it mainly depends on the type and design of the furnace you choose, as straight and corrugated furnace chambers can be used together. The choice of furnace chamber is mainly a matter of stress, to prevent the various components of the furnace from becoming unstable. The number of waves needs to be taken into account, as well as whether there are straight sections. The best configuration should be chosen without causing instability; the maximum and minimum values should be calculated, and the middle value selected. It is also necessary to determine whether this configuration results in optimal steady-state conditions.
Thank you all for your answers. I’ve learned something new again.
