Introduction

> Yuanda Water Tube Boiler
Certified by ASME, CE, ISO, EAC, DOSH, TUV, BV, ensuring high quality and compliance with international standards.
> Introduction: SZL Series Coal Boiler
SZL water tube coal fired boiler, suitable for capacity demand in 2ton-50ton.
It's kind of double-drums (A/D type) water tube assembly chain grate boiler . High technology, environmental and energy-saving. Large heating surface, make sure enough space for biomass burning, automatic fuel feeding and slag removing system.
> Core Technology of SZL Boiler:
1. Cyclone chamber structure, high-temp flue gas through high-speed rotation/mixing combustion/dust separation, achieving dust removal & energy saving & environmental protection.
2. Indenpend wind chamber structure, make air regulation sensitive and make wind uniformly, resolve the wind plug, wind channeled, partial burn phenomenon.
3. Membrane water wall construction, structure advantages of high heat transfer coefficient, good heat transfer effect, low heat loss, good air tightness of furnace wall.
