Abstract
The invention discloses a kind of gas fired-boiler economizer connecting line system, including: feed pipe and drum, drum connecting bypass feed pipe and recirculation pipe respectively, on bypass feed pipe, economizer exit header is set, it is provided with recycle valve and coal device inlet header on recirculation pipe, between coal device inlet header and economizer exit header, economizer is set and is connected；Coal device inlet header is connected with feed pipe, feed pipe is provided with feed water check valve, is provided with economizer inlet valve between coal device inlet header and feed water check valve.Any valve is not set, in order to successfully the steam water interface produced in economizer being imported drum, the operation of economizer is more reliable and more stable between coal economizer exit header and pot letter；Meanwhile, enormously simplify the connecting line of economizer.
Description
Technical field
The present invention relates to boiler technology field, especially, relate to a kind of gas fired-boiler economizer connecting line system.
Background technology
Economizer is the heating surface of saturation water boiler feedwater being heated in boiler back end ductwork under drum pressure, due to
The heat of the low-temperature flue gas that it absorbs, reduces the exhaust gas temperature of flue gas, saves the energy, improve efficiency.Traditional combustion gas
Boiler economizer connection system structure is the most more complicated, and connecting line is a lot, so can reduce the reliability of economizer work with
Stability, is susceptible to reveal.
Summary of the invention
Present invention aim at providing a kind of gas fired-boiler economizer connecting line system, to solve in prior art, combustion
Gas boiler economizer connection system complicated structure, connecting line is many, can reduce the reliability and stability of economizer work,
Be susceptible to reveal problem.
For achieving the above object, the present invention provides a kind of gas fired-boiler economizer connecting line system, including: feed pipe with
Drum, described drum connecting bypass feed pipe and recirculation pipe respectively, described bypass feed pipe arranges economizer exit header,
Being provided with recycle valve and coal device inlet header on described recirculation pipe, described coal device inlet header joins with described economizer exit
Arrange economizer between case to connect；Described coal device inlet header is connected with described feed pipe, and described feed pipe is provided with feedwater
Check-valves, is provided with economizer inlet valve between described coal device inlet header and described feed water check valve.
Further, described feed pipe is provided with water supply safety valve.
The method have the advantages that
Any valve is not set, in order to the steam-water mixing that successfully will produce in economizer between coal economizer exit header and pot letter
Thing imports drum, and the operation of economizer is more reliable and more stable；Meanwhile, enormously simplify the connecting line of economizer.
Accompanying drawing explanation
Below with reference to figure, the present invention is further detailed explanation.The accompanying drawing of the part constituting the application is used for
Thering is provided a further understanding of the present invention, the schematic description and description of the present invention is used for explaining the present invention, is not intended that
Inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of gas fired-boiler economizer connecting line System Preferred embodiments of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
Referring to Fig. 1, the preferred embodiments of the present invention provide a kind of gas fired-boiler economizer connecting line system, bag
Include: feed pipe 1 and drum 2, described drum 2 connecting bypass feed pipe 3 respectively and recirculation pipe 4, described bypass feed pipe 3 sets
Putting economizer exit header 8, on described recirculation pipe, 4 are provided with recycle valve 6 and coal device inlet header 7, described coal device import
Arrange economizer 9 between header 7 with described economizer exit header 8 to be connected；Described coal device inlet header 7 and described feed pipe 1
Connect, described feed pipe 1 is provided with feed water check valve 11, between described coal device inlet header 7 and described feed water check valve 11
It is provided with economizer inlet valve 5.
During work, water enters into drum 2 by feed pipe 1, economizer 9 with bypass feed pipe 3, after heating, and water warp
Recirculation pipe 4 flows out, and enters into drum 2 through economizer 9 the most again and completes waste heat recovery.This gas fired-boiler economizer connecting tube
Any valve is not set, in order to successfully by generation in economizer 9 between coal economizer exit header 8 and the pot letter 2 of road system
Steam water interface imports drum 2, and the operation of economizer 9 is more reliable and more stable；Meanwhile, enormously simplify the connecting tube of economizer 9
Road.
Preferably, for improving the safety in operation of pipeline, described feed pipe 1 is provided with water supply safety valve 10.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention；Skill for this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
