WNS Corrugated Boilers: An Engineering Breakthrough for Low-Carbon Production

Introduction

The furnace design of gas steam boilers is crucial for stable operation. When the burner ignites, the flame requires an optimally designed combustion space that directly impacts fuel efficiency, heat transfer, and overall boiler performance. This article examines the structural advantages, material selection, and production processes behind WNS series boilers’ corrugated furnace design.

Furnace Structure Design
