WNS Condensing Steam Boiler

Introduction

Model specification and Configuration Illustration

Rated Pressure:0.7-2.5MPa

The configuration of Steam(Water) distributor:configures the number of tube socket of output and input according to the workshop's require

The configuration of water treatment devices:configures water treatment device according to the hardness of water

Fuel Instruction:Up to Client's demand,Natural gas,town gas,liquefied gas or methane

Unique position of the furnace type
Preferred Energy-saving steam boiler

WNS series condensing steam boiler is two-pass fire tube boiler with wet back smoke-transfer chamber, spirally corrugated tube technology , air pre-heater at the front of boiler.The energy-saving condenser at the top achieves third pass smoke flow,so that fresh air can fully absorb the waste heat from the flue gas to lower the waste smoke temperature to 60 degree centigrade. It is split-type frequency conversion burner, and mature technology, safe and stable operation, high heat efficiency,and is packaged in stainless steel, which looks elegant.
