What are the Technical Parameters and Furnace Capabilities of the WNS4-1.6-Q(Y) Boiler?

1. Understanding the WNS4-1.6-Q(Y) Boiler
The WNS4-1.6-Q(Y) boiler refers to a horizontal internal combustion boiler with a rated evaporation capacity of 4 tons/hour (t/h) and a rated working pressure of 1.6 MPa. The "Q(Y)" designation indicates that the equipment is designed to operate on gas or liquid fuels. In industrial applications, such as pulp mills, utilizing process gas streams requires precise calculation of the WNS4-1.6-Q(Y) boiler's combustion chamber parameters to ensure safety and efficiency.

2. Why Furnace Temperature and Flow Rates Matter
For a feasibility study involving gas streams from a pulp mill, understanding the maximum withstand temperature of the furnace is critical. The furnace temperature affects the heat transfer efficiency and the lifespan of the material. Additionally, the specific fuel and air flow rates are essential for the WNS4-1.6-Q(Y) boiler to maintain stoichiometric combustion, preventing incomplete combustion or excessive thermal NOx emissions. These parameters depend heavily on the calorific value and composition of the specific gas stream provided by the client.

3. How to Determine Optimal Operation Parameters
To determine the exact flow rates for a WNS4-1.6-Q(Y) boiler, a detailed fuel analysis report is required.

Furnace Temperature: Generally, the corrugated furnace of a standard WNS boiler is designed to withstand combustion temperatures exceeding 1000°C - 1300°C, utilizing high-quality steel materials suitable for pressure vessels.
Flow Rates: The burner management system (BMS) modulates the air-to-fuel ratio. For a 4-ton boiler, the gas consumption is calculated based on the fuel's Low Heating Value (LHV).
4. Advantages of ZOZEN WNS Series Boilers
ZOZEN’s WNS4-1.6-Q(Y) boiler features a large diameter corrugated furnace. This design not only increases the heat transfer area but also effectively absorbs thermal expansion, ensuring the equipment operates stably under high-temperature conditions. The boiler utilizes threaded smoke tubes to enhance heat transfer, achieving a thermal efficiency of over 98% when equipped with a condenser.

5. Manufacturer Strength: ZOZEN Boiler
ZOZEN Boiler holds the ASME "S" and "U" stamps and is a boiler manufacturer mainly for export. We have extensive experience in customizing combustion systems for special fuels found in paper and pulp industries. Our engineering team can simulate combustion based on the specific gas composition from the Uruguay project to provide precise data on flow rates and temperature limits.
