Product Introduction

The WNS integrated condensing boiler delivers more significant energy savings, with thermal efficiency exceeding 100%. This model is a horizontal, two-pass, wet-back fire tube boiler. During operation, the high-temperature flue gas from combustion in the furnace enters the second pass tubes through the reversal chamber, then passes through the front flue box, transition duct, condensing economizer, and chimney before finally being discharged into the atmosphere.
