Steam main pipe connects boiler water drum.Steamdrum mainly carries out steam-water separation, and water drum, which mainly collects, divides water to act on.
In a kind of aforementioned gas fired-boiler stand-by heat activation system, the top of boiler steamdrum connects the first valve body, boiler
The bottom of steamdrum connects the second valve body, is equipped with water-level gauge between the first valve body and the second valve body, and the downstream of water-level gauge is equipped with the
Three valve bodies.Steam is continually introduced in boiler, and steam water-level can increase in stove, and can be opened when steam water-level reaches high water level
One valve, the second valve, third valve discharge water, and can be recycled again if the water of releasing is qualified after testing.It can be with
The water level of boiler steamdrum is learnt by observing water-level gauge.
In a kind of aforementioned gas fired-boiler stand-by heat activation system, user's pipeline is further included, the superheated steam of superheater goes out
Mouth connects user's pipeline.High-temperature steam is oriented to by stand-by heat steam main pipe by user's pipeline.
In a kind of aforementioned gas fired-boiler stand-by heat activation system, boiler hot reserve steam main pipe connection user's pipe
Road.
Compared with prior art, the utility model can shorten the time of boiler cold-state startup, can be rapidly increased to completely bear
Lotus state.Drawing steam all the way, to boiler water drum heating boiler feed water, makes boiler be in hot stand-by duty, can quickly be opened when needing
It is dynamic to rise to full load condition.
