Product core technology

Condensation technology

During the combustion of natural gas, a certain proportion of carbon dioxide and water vapor will be produced. During the operation of traditional gas boilers, these flue gases and water vapor are directly discharged from the exhaust pipe into the atmosphere. The exhaust temperature is very high and the thermal efficiency is low. Emissions seriously exceeded standards. The condensing boiler absorbs and utilizes the sensible heat in the flue gas and the latent heat released by the condensation of water vapor, and directly converts it into heat energy in the boiler, thus improving the thermal efficiency of the boiler. Due to the improvement in efficiency, when meeting the same heat load, the natural gas required is reduced accordingly, thereby reducing the emission indicators of CO, COz and NOx in the flue gas, making the use of natural gas cleaner and more environmentally friendly.

Fully premixed low-nitrogen combustion technology

Full premixing technology is to fully mix the air and natural gas before entering the combustion chamber through a variable frequency fan and proportional gas valve to adjust the air-fuel ratio. In this way, the demand for air can be controlled, the dew point of the flue gas can be increased, and the flue gas can enter the condensation stage as early as possible to further improve the thermal efficiency. At the same time, the flame temperature can be lowered to reduce the production of NOx, so that the lowest emission of NOx can be controlled under operating conditions. to less than 30mg/Nm3.

Combustion proportion adjustment technology

The intelligent boiler controller cooperates with the natural gas proportional adjustment solenoid valve and the fully premixed variable frequency fan to ensure the best air-fuel ratio, and automatically adjusts the boiler output to meet the dynamic heat load, so that the heat output of the boiler is as close as possible to the dynamic heat load demand and reduces ineffective output. , while achieving the lowest emission effect.

Due to the high thermal efficiency, the gas burns more fully, which not only extends the service life of the fully premixed condensing boiler, but also greatly reduces maintenance work such as cleaning up carbon deposits.

Product Features

Our condensing boilers offer a wide range of features that make them an excellent choice for heating and hot water applications. Here are some of the key features of our condensing boilers:

1.High efficiency and energy saving: The tracking valve opening technology is adopted to effectively reduce the heat loss of the exhaust gas. The thermal efficiency is as high as 106%, which is more than 20% higher than that of ordinary boilers. The practical gas volume is more than 20% lower than that of ordinary boilers.

2. Customization: We offer custom condensing boilers that can be tailored to meet the specific needs of our clients. Our technical team can work with you to design a boiler that meets your requirements and delivers optimal performance.

3.Intelligent control: Comprehensive functions, one-button operation; the boiler can be started and stopped remotely through the mobile phone, and the boiler operating status can be monitored, truly unattended. 

4.Green and environmentally friendly: NOx emissions are lower than 30mg/Nm3, meeting China’s increasingly stringent boiler nitrogen oxide emission standards.

5.Easy to install: The boiler is small in size and light in weight. It has a wheeled support and uses PVC pipes as exhaust pipes. It is easy to install, thus saving the installation costs of the boiler and smoke pipes and shortening the installation cycle.

6.Worry-free after-sales service: The product has a simple structure, high-quality accessories, strong versatility, and few wearing parts; it realizes remote after-sales management of the boiler and provides timely and fast after-sales service.

7.Multiple units online: According to the actual heating load, flexible combination can realize parallel operation of multiple boilers, reducing resource waste and gas consumption.

8.Cost-effective: Our condensing boilers offer excellent value for money, with competitive prices and low running costs due to their high energy efficiency.

9.Safe and stable: With multiple protection functions, the safety performance is more comprehensive. The safety control is more reliable; all operating faults are accurately identified, false faults are automatically repaired, and the operation is more stable.

Overall, our condensing boilers offer a range of features that make them an excellent choice for heating and hot water applications. They are highly efficient, customizable, durable, environmentally friendly, safe, easy to install, and cost-effective.
