Frequently Asked Questions
The double drum design, combined with ascending calandria, eliminates dead water zones and prevents sludge accumulation, enhancing the cooling of the high-temperature region and preventing boiler bottom bulge.
Spirally corrugated tubes increase the heat transfer surface area and create turbulence in the water flow, which speeds up temperature rise and significantly enhances the steam generation rate.
Yes, the SZL series is designed for versatility and can efficiently operate using either coal or biomass fuels via the chain grate system.
The rational design of the furnace arch improves combustion conditions and enhances the dust falling function, which minimizes the amount of pollutants released into the atmosphere.
The use of an arched tube sheet combined with spirally corrugated tubes absorbs thermal expansion stress, effectively preventing the tube sheet from cracking during temperature fluctuations.
Good sealing ensures that air is distributed rationally across the grate, reducing the air excess coefficient and preventing heat loss, which directly increases the boiler's overall thermal efficiency.
