Introduction

SZL/SZW Water Tube Biomass Boiler
Yuanda SZL series water tube boiler, water membrane walls design & double drums layout "A" Or "D" type structure, equipped with combustion device: chain grate/reciprocating grate.
SZL Biomass Boiler Advantages
SZL biomass boiler design capacity in 4ton-50ton. Advantages: High technology, environmental and energy-saving. Large heating surface, make sure enough space for biomass burning, automatic fuel feeding and slag removing system.
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.
