Introduction

Low-nitrogen technology: To achieve low nitrogen emissions, the combustion chamber of low-nitrogen boilers adopts a large-volume design, significantly reducing the volumetric heat load of the furnace. Combined with the use of low-nitrogen burners, it ensures that NO emissions in the flue gas meet the standard of ≤30mg/Nm³

Product Material Introduction

1.Boiler shell and furnace liner: Generally, boiler specific carbon steel plates such as Q245R and Q345R are used. The furnace often adopts a corrugated tube structure to cope with thermal expansion
2.Insulation material: Made of high-quality aluminum silicate fiber cotton, wrapped in stainless steel plate to reduce heat loss
3.Tail flue: The condensing section flue is covered with stainless steel or enamel coating

Main purpose

The WNS series low nitrogen boilers are currently the mainstream and preferred choice in the distributed steam heating market, widely used in places that require clean, automatic, and efficient steam

Food and beverage industry: brewing, dairy products, meat processing, central kitchen steaming, sterilization, disinfection
Textile printing and dyeing industry: dyeing, shaping, drying, ironing
Chemical industry: pharmaceuticals, rubber vulcanization, light chemical raw material production heating.
Washing industry: laundry rooms and ironing machines in hotels, hospitals, and laundry factories.
Building materials industry: concrete curing, gypsum board drying.
Heating industry: Regional or building heating (through steam water heat exchange stations).

Core strengths

Environmentally friendly low nitrogen emissions	NOx emissions can be consistently below 30mg/m ³, meeting the environmental standards of most regions, making it a reliable choice for "coal to gas" and environmental transformation
Low operating costs	Fully utilize the latent heat of flue gas, significantly reducing fuel costs
Compact structure, easy to install	Overall factory production, short installation cycle, and low infrastructure cost.
Safe and reliable, with durable quality	Adopting mature boiler manufacturing technology, stable and reliable operation

Target audience

The WNS series low nitrogen gas steam boiler represents a high level of technology for small and medium-sized oil fired gas boilers. For the vast majority of industrial and commercial users who require 1-20 tons/hour of steam, it is a benchmark solution that combines compliance, economy, and reliability in the context of increasingly stringent environmental regulations.
