Product Description

SZL series coal fired steam boiler is a horizontal double boiler tube vertical chain boiler water tube steam boiler. The boiler has the advantages of compact structure, small floor space, short installation cycle, convenient site installation, low cost and simple operation. The boiler drum is arranged vertically along the center of the boiler. The boiler drum and the water wall tube on both sides constitute the radiant heating surface of the furnace, and the tube bundles between the upper and lower boiler tubes constitute the convection heating surface. Horizontal steam boiler is suitable for industrial and domestic steam.

Technical Advantages

High Efficiency and Energy Saving

The large area heating surface of industril steam boiler makes the start to heat up quickly, the flue gas returns to heat exchange, and the heat production efficiency is high.
After high temperature flue gas combustion, through two back side scour convection heating surface, to the economizer, and finally into the dust collector, from the chimney discharge.
The special design of the arch of the grate furnace is equipped with an independent air tank to adjust the air volume independently.

Safe and Reliable

The boiler is equipped with automatic control, monitoring instrument, spring fully open safety valve to ensure safety, maintenance platform, manhole and access door, can be opened for convenient operation and maintenance.
In addition to the water level safety Settings specified in the national standards, we have very low water level electrode protection to ensure the safety of the water level in horizontal steam boiler.
