2019-04-29

New Fengneng Tube Low Nitrogen Condensing Hot Water and Vacuum Boiler Integrated Design
1. The Fengneng Pipe series boilers adopt a refined design concept that deeply integrates "pot" and "furnace". Through measures such as full structure, full process numerical simulation, and digital control, the structure is continuously optimized to achieve matching in energy efficiency, emissions, and power consumption.

2. Introducing fully premixed planar combustion technology, the product not only meets high thermal efficiency and heat transfer performance, but also has a small volume, reduces user footprint, and lowers user infrastructure investment costs.

3. The built-in design of each device enables the debugging of the product to be completed before leaving the factory. At the user's site, only the water outlet pipeline, natural gas pipeline, chimney, and power can be connected for use, which not only shortens the installation time but also saves installation costs;

High thermal efficiency and low smoke temperature: Increase the heat exchange surface by more than 5 times, increase the heat exchange efficiency, penetrate deep into the smoke center, and quickly reduce the smoke temperature.

Humanized control system: LCD touch screen, dynamic graphic displayMulti level menu and permissions, automatic fault recording

Small footprint: reduced compared to ordinary condensing vacuum boilersLess occupied area by about 30%

Multi purpose: Single, series, and parallel can be freely combined and matched

Fengneng Tube Condensation Technology

1. CFD numerical simulation analysis

Applying CFD numerical simulation analysis techniques to optimize the heat transfer performance of Fengneng heat exchange tubes;

2. Increase heat exchange area by more than 5 times

Increase the heat exchange area by more than 5 times. More heat can be displaced from the flue gas, thereby increasing the heat transfer efficiency;

3. The heat transfer element penetrates deep into the center of the flue gas

The heat transfer element penetrates deep into the center of the flue gas, rapidly reducing the temperature of the flue gas;

4. Silicon aluminum alloy

Using high thermal conductivity silicon aluminum alloy heat transfer components to extend the service life of pressure bearing components;

5. Unique concave convex groove

The unique concave convex groove design greatly improves the heat transfer performance of the heat exchange tube in the condensing state.

1. The condenser adopts a silicon aluminum alloy material for the Fengneng tube, which is resistant to corrosion in flue gas environments and durable;

2. The heat transfer method and structural design of Fengneng tube enable deep condensation of flue gas and high heat transfer efficiency;

3. The cooling water of the Fengneng tube condenser flows outside the tube, which is not easy to scale and is easy to clean, with low water quality requirements; Contrary to the design concept of traditional condensers, the cooling water of traditional condensers flows through the pipes, which is prone to scaling and difficult to clean, requiring extremely high water quality;

4. The condenser adopts heat exchange between flue gas and water, with a high heat transfer coefficient, and the temperature difference between exhaust gas and feedwater is within 5 ℃ (80 ℃/60 ℃ working condition, 60 ℃/50 ℃ working condition);

5. Fully utilizing the structure and external space of the boiler and condenser, reducing the total volume of the boiler;
