LSS vertical series steam boiler is three-pass steam boiler with top-fired burner. The flame can completely spread from the top to the bottom and burn sufficiently. The gas makes a three-return heat transfer, so the heat loss is reduced and the thermal efficiency is higher.



1. Compact structure, small footprint 

The boiler floor space is reduced as much as possible, after the precision calculation by our professional engineers and on the premise of guarantee the boiler output, thus the user can save the space and cost. 

2. Sufficient output 

The boiler heating area is sufficient, fully absorb the effective heat, the exhaust gas temperature is low, thermal loss is low, thus it can have sufficient heating and big radiation heating surface. 

3. Quick steam production, high steam quality 

This kind of boiler takes only 20 minutes from cold running to full load due to its own features, and it is applicable for the condition of on-off operation, can provide steam quickly and timely. It adopts the steam separator inside the drum to separate steam, thus can guarantee the steam dryness. 

4. Reliable pressure and water level protection, high safety performance 

The boiler volume is small,thus degree of damage caused probably is smaller than other boilers. The safety performance is higher due to various controlling protection,such as the pressure and water level protection,super smoke temperature protection. 

5. Quick-loading, easy to install

LSS series boiler is small size quick-loading boiler,vibration is low when operation,no special requests on foundation. 

6. Environmental protection 

The boiler has the function of dust removal, which makes the soot discharge meet the national environmental standards requirements.
