SZL Series Water Tube Boiler

SZL Series Water Tube Boiler Introduction

Water tube boiler refers to the boiler that water, steam or the steam-water mixture flows in the tubes, and fire or the smoke are combustion and flow outside the flues. Compared with fire tube boiler, water tube boiler has no limitation on steam capacity and pressure, so it is fit for the user who need large capacity. Moreover, coal fired water tube boiler has higher requirement for water quality and more space for superheater. Otherwise, water tube boiler good heat transfer property, high combustion efficiency, heating area can be layout at different types.

Zozen Boilers SZL series coal fired water tube boiler is the horizontal type double drum longitudinal type chain grate water tube steam boiler. Zozen Boilers inherits the domestic current mature technique of SZL assembly chain grate boiler, gains technological breakthrough on the following areas: furnace with water-cooling chamber, back-arch structure design, boiler design with low thermal inertia, seal structure on membrane wall, and contact side seal of the grate.

SZL Series Water Tube Boiler Application

Zozen Boilers coal fired water tube boiler is widely used in light textile industry, chemical engineering, printing and dyeing plant, and oil field, rice mill, garment factory, etc., moreover, it can used for heating in hotel, civil architecture, school, and it is utility for power plant.

SZL Series Water Tube Boiler Advantage

• Whole membrane water cooling combustion chamber and inverted “α” arch furnace technology achieve high combustion efficiency, high output
• Extended length of the grate, extended the coal burning time, improved the boiler thermal efficiency
• Light furnace wall structure reduce heating loss, thermal inertia decrease 70%, furnace heat up fast, boiler start-up and shut down quickly
• Flexible load adjustment
• Anti-coking heater design, remove the side sealing steel, avoid the problem of grate stuck and uneven air distribution for combustion.
• Adopt light rail I-beam for the rail under the grate, abrasion resistance and difficult for deformation, improve the reliability of boiler operation.
