Introduction

The SZL series double-drum vertical chain grate water tube steam boiler adopts a quick installation or assembly structure. For 4-6t/h capacity, it is a quick installation water tube structure and is fully assembled in the factory before delivery. For 6-35t/h capacity, it consists of two major components: the upper part is the heating surface, and the lower part is the combustion equipment. The high-temperature flue gas is directed through the convection heating surface and passes through an economizer and dust collector before being discharged.

Advantages

Chain Grate: Layered combustion method, with wide fuel adaptability, A dual-layer structure grate frame, without skewing or jamming.
Ultra-Low Water Level Electrode: Add an ultra-low water level electrode protection, Interlocked with the drum and induced draft fan to ensure the water level safety.
Fuel Stirrer Speed Regulator: Deliver materials evenly to prevent backfire, Appropriate rotational speed based on the combustion rate of biomass.
Independent Air Chamber: Independent air chambers vary in number based on boiler capacity, The air distribution can be adjusted to ensure complete fuel combustion.
