Exploring New Technologies in Industrial Boilers: ZOZEN’s Three Pass Wet Back Boiler

Introduction
In the industrial sector, boilers serve as crucial energy conversion devices that significantly enhance production efficiency and ensure reliable energy supply. Today, we will focus on a high-performance and eco-friendly boiler: the ZOZEN three pass wet back boiler. This article will detail the features and advantages of this boiler from five perspectives.

1. Structure Analysis of the Three Pass Wet Back Boiler

The three pass wet back boiler is a high-efficiency boiler characterized by its wet back design, where the rear wall of the boiler is water-cooled. This design significantly improves the boiler’s thermal efficiency. Additionally, the three pass design allows flue gas to circulate three times within the boiler, fully absorbing heat and further enhancing thermal efficiency.

Other structural features of the three pass wet back boiler include:

1. Wet Back Design: The water-cooled rear wall improves thermal efficiency.
2. Three Pass Design: Flue gas circulates three times, maximizing heat absorption.
3. High-Performance Combustion Chamber: Advanced combustion technology increases combustion efficiency and reduces energy consumption.
4. Flue Gas Purification System: Equipped with an advanced flue gas purification system, it reduces pollutant emissions and meets environmental standards.

2. Introduction to ZOZEN Three Pass Wet Back Boiler

ZOZEN Boilers is a high-tech enterprise specializing in the research, production, and sales of boilers and thermal equipment. The company adheres to the philosophy of “innovation, excellence, and environmental protection,” dedicated to providing customers with efficient, energy-saving, and eco-friendly boiler solutions.

WNS Series Three Pass Wet Back Boiler：

• Boiler Capacity: 1-20 T/H
• Working Pressure: 0.7-2 Mpa
• Product Description: The three pass wet back boiler operates automatically, with fuel atomized by the burner forming a flame that fills the full-wave furnace. This constitutes the first pass. The high-temperature flue gas generated during combustion converges in the combustion chamber, turning to enter the second pass, which consists of the threaded smoke tube bundle area. After convective heat exchange, the flue gas temperature gradually decreases as it moves to the front smoke box, where it turns into the third pass, the light tube bundle area, before entering the economizer and chimney, finally being discharged into the atmosphere.
