Fuel (gas) hot water boiler (condensing integrated)

It adopts high-quality imported European burners with excellent performance and complete combustion; the boiler is a horizontal wet-back structure with a sufficiently large water space and steam space, and a large heating surface; the insulation uses high-thermal-resistance fiber of more than 120mm and a closed stainless steel shell, with good heat insulation performance, making the boiler surface temperature ≤45℃, and reducing heat loss; the boiler tail is equipped with a high-efficiency needle-tube economizer, making the boiler thermal efficiency as high as 92% or more. If a low-temperature high-efficiency economizer + condenser is used, the boiler thermal efficiency can be as high as 97.0% or more.

Product Description

1. Junpeng Boiler Advantages:
★Beautiful appearance, compact structure; reasonable design, safe and reliable performance
Gas steam boiler (standard three-return): The boiler body of our company is designed as a full wet-back, horizontal internal combustion three-return, full corrugated furnace structure. The boiler has a large capacity and low thermal stress, greatly improving the boiler's lifespan and safe and reliable performance.
Gas steam boiler (condensing integrated structure): The boiler body of our company is designed as a full wet-back, horizontal two-return + condensing integrated, full corrugated furnace structure. The boiler has a large capacity and low thermal stress, greatly improving the boiler's lifespan and safe and reliable performance.
★Large heating surface area, complete combustion, low pollutant concentration
Our company's boiler furnace has low back pressure, which is especially suitable for imported burners. The furnace structure and flame shape are perfectly combined, giving the boiler a large overload capacity. The large-space furnace structure is conducive to the complete combustion of fuel, resulting in low flue gas pollutant concentration and greatly reducing NOx emissions.
★High degree of intelligence
It adopts an advanced PLC control system. The carefully designed software control system can perform real-time and comprehensive intelligent fault identification and processing of the boiler according to the current operating conditions; it can achieve fully automatic intelligent control through pre-set operating modes; it can be remotely centrally controlled, with all plug-in components, making maintenance extremely convenient.
★High thermal efficiency, low operating costs
It uses high-quality imported burners from Europe, with excellent performance and complete combustion; the boiler has a horizontal wet-back structure, a sufficiently large water space and steam space, and a large heating surface; the insulation uses more than 120mm of high thermal resistance fiber and a closed stainless steel shell, with good heat insulation performance, making the boiler surface temperature ≤45℃ and reducing heat loss; the boiler tail is equipped with a high-efficiency needle tube energy saver, making the boiler thermal efficiency as high as 92% or more. If a low-temperature high-efficiency energy saver + condenser is used, the boiler thermal efficiency can be as high as 97.0% or more.

2. Boiler Body Structure


(1) The WNS type oil/gas boiler is a typical wet-back three-return fire tube boiler.
As shown in the figure: The main body of this boiler is a welded structure. It includes the cylinder, furnace, combustion chamber, tube plate, threaded tube, front and rear smoke boxes, base, and internal and external accessories.
The combustion flue gas flow principle is that the flame ejected from the burner is sprayed longitudinally at high speed towards the furnace. Because this boiler is a slightly positive pressure furnace, under the action of pressure, the flue gas turns in the combustion chamber and enters the first tube group. Then it turns in the front smoke box and enters the second tube group, continuing to flow back. The high-temperature flue gas flows through two groups of threaded smoke tube groups. Finally, after sufficient heat exchange, the low-temperature flue gas passes through the rear smoke box to the energy saver, and after heat exchange through the energy saver, it is discharged.

The combustion flue gas flow principle is that the flame ejected from the burner is sprayed longitudinally at high speed towards the furnace. Because this boiler is a slightly positive pressure furnace, under the action of pressure, the flue gas turns in the combustion chamber and enters the first tube group. Then it turns in the front smoke box and enters the energy saver and condenser for heat exchange, and the high-temperature flue gas continues to flow forward through two groups of finned tube groups. Finally, it is discharged after heat exchange through the condenser.
The boiler internal water circulation is a natural circulation method. That is, after the furnace water is intensely heated on the furnace and flue tube walls, it rises, and steam-water separation occurs at the steam-water interface, and the separated steam enters the upper steam space of the cylinder. The furnace water descends along the inner wall of the cylinder and re-enters the lower part of the cylinder, and is heated again by the furnace and flue tubes before rising.
Because the flue tubes adopt advanced threaded flue tube technology, compared with ordinary bare tube boilers, the boiler's heat exchange capacity is increased by 20%~50%, greatly improving the boiler's working efficiency and reducing the boiler's manufacturing cost.
A steam-water separator is installed inside the boiler steam outlet to ensure the quality of the steam. An inlet pipe is installed where the boiler inlet water passes through the boiler drum, and a special guiding device is installed inside the boiler drum.
