Product characteristics of low nitrogen high-efficiency condensing hot water boiler

Quanxin brand low nitrogen high-efficiency condensing hot water boiler is a steel gas atmospheric pressure hot water boiler independently developed by the company. It has the characteristics of ultra-low nitrogen emissions (NOx<30mg/m3), high condensing efficiency (102%), and modular combination application. All indicators of the entire series of products can meet the requirements of relevant national energy-saving and environmental protection policies, with high cost-effectiveness, making it an ideal low nitrogen transformation application product. The product is manufactured with a small footprint, simple operation, easy use and maintenance, and has no special requirements for the water quality of the hot water system. The ordinary open circuit system can provide direct supply without the need for a secondary system, and the load regulation combustion can provide on-demand heating. It can achieve climate compensation control, linkage control, remote monitoring and other functions.

The steel furnace body adopts advanced fast cooling technology design and a large furnace multi pass structure, effectively suppressing the generation of NOx during the combustion process. It can achieve stable low nitrogen emissions without relying on complex low nitrogen combustion technologies such as flue gas recirculation or surface combustion; The stainless steel condenser, which is resistant to low-temperature corrosion, adopts a labyrinth arrangement of fully finned heat exchange tubes to increase flue gas disturbance and improve heat transfer efficiency. It utilizes full flow low-temperature return water to absorb sensible heat and latent heat of water vapor condensation in the flue gas to the maximum extent, truly achieving the goals of low nitrogen efficiency, energy conservation and environmental protection. It also has the advantages of simple operation, strong anti-interference ability, convenient maintenance, stable operation, and high service life.
