The SZL series steam boiler stands out in the realm of industrial boilers with its distinctive design and construction. It is a water tube boiler featuring a double drum and a chain grate stoker structure that epitomizes efficiency and durability in steam generation. The SZL series comes in two main configurations: the 4-6 tph (tons per hour) range and the 6-35 tph range. The 4-6 tph models are package boilers, which means they come fully assembled from the factory, making installation and setup straightforward and less time-consuming. This design is particularly advantageous for smaller operations or those with limited space, as it negates the need for extensive on-site assembly. On the other hand, the 6-35 tph models of the SZL series are shop-assembled structures. These larger boilers come in two main parts: the upper module, which comprises the heat absorbing surfaces, and the lower module, which houses the combustion equipment.
