In industrial production, a boiler model may seem like a complicated string of letters and numbers, but it actually contains the core "identity information" of the equipment. Taking the Yongxing Boiler NWNS 1-1.25-YQ as an example, understanding its model code helps you accurately match production needs and select the right high-efficiency and energy-saving steam heat source.
1. NWNS: The "ID Card" of Structure and Fuel
The first part of the boiler model, "NWNS", directly defines the structural form and fuel characteristics of this Yongxing boiler.
N: Represents Yongxing’s unique condensing high-efficiency series, different from the standard WNS type. Its key advantage is high-efficiency recovery of flue gas waste heat, with thermal efficiency exceeding 100%.
W: Stands for horizontal layout, featuring a compact footprint and easy installation.
N: Indicates an internal combustion structure, where fuel burns inside the furnace for more direct heat transfer.
S: Means chamber combustion furnace, in which fuel is fully suspended and burned in the furnace, delivering high combustion efficiency and low pollutant emissions.
In short, NWNS is a specialized boiler developed by Yongxing, characterized by horizontal internal combustion, high condensing efficiency, and low-nitrogen environmental protection, suitable for green production in modern industry.
2. 1-1.25: The "Performance Indicators" of Core Parameters
The middle code "1-1.25" represents key indicators of the boiler’s rated capacity and pressure-bearing capacity, which determine its applicable scenarios.
1: Rated evaporation capacity of 1 ton per hour, stably producing 1 ton of saturated steam per hour to meet the continuous steam demand of small and medium-sized enterprises in chemical, food, textile and other industries.
1.25: Rated working pressure of 1.25 MPa, corresponding to a steam temperature of approximately 194°C. It provides stable pressure and high-quality steam, suitable for production processes with standard requirements for pressure and temperature.
This set of parameters precisely matches the core needs of small and medium-sized enterprises for "stable steam supply and moderate pressure", making it a classic configuration for industrial boilers.
3. YQ: The "Flexible Fuel Compatibility" Feature
The final code "YQ" specifies the fuel types compatible with the boiler, highlighting its operational flexibility.
Y: Represents oil fuel, compatible with light oil, heavy oil and other liquid fuels.
Q: Represents gas fuel, suitable for natural gas, liquefied petroleum gas, town gas and other gaseous fuels.
The combination "YQ" means an oil-gas dual-fuel boiler. Enterprises can switch freely between fuels based on local fuel prices and supply conditions, reducing fuel costs and coping with supply fluctuations.
