Ultra-low Nitrogen (NOx) Condensing Vacuum Hot Water Boiler

By adopting the revolutionary planar combustion ultra-low nitrogen tube bundle water-cooled furnace body technology, the planar combustion is composed of tens of thousands of micro-flames. Combined with the unique tube bundle type furnace body structure of the boiler, the flames are cooled rapidly, which greatly inhibits the generation of nitrogen oxides (NOx), and the nitrogen oxides (NOx) emissions are reduced to less than 15mg/m3.

Product Description

By adopting the revolutionary planar combustion ultra-low nitrogen tube bundle water-cooled furnace body technology, the planar combustion is composed of tens of thousands of micro-flames. Combined with the unique tube bundle type furnace body structure of the boiler, the flames are cooled rapidly, which greatly inhibits the generation of nitrogen oxides (NOx), and the nitrogen oxides (NOx) emissions are reduced to less than 15mg/m3.

The tubular furnace structure has a high heat transfer coefficient, requires less water storage, and can produce hot water within 5 minutes after startup. During the blowdown process, the heat loss is reduced by 20%, there is no preheating load loss, and the operating efficiency reaches as high as 104%.

It has truly achieved ultra-low nitrogen emissions, low noise levels, and high efficiency operation.

Product Advantage

Ultra-low nitrogen premixed flat burner: Ultra-low nitrogen premixed flat combustion technology

U-shaped stainless steel 304 heat exchanger:

High heat transfer coefficient, high pressure resistance, capable of natural expansion and contraction, detachable, easy to maintain, long service life

Heat transfer reaction water pipe:

Enhance the heat exchange efficiency. The preheating process only takes 5 minutes, with no loss of preheating load. The combustion takes place in the water pipes, with a low combustion temperature, which significantly controls the production of nitrogen oxides.

Stainless steel 304 condenser:

Absorb latent heat, reduce smoke density, enhance boiler thermal efficiency, and be corrosion-resistant.

Self-priming safety valve：

Achieve 100% safety, automatic pressure relief, and negative pressure adsorption

Intelligent Control:

Intelligent touch screen displays Chinese text for working conditions, offers remote control, and has an online operation guide.
