— Differences between DZL and SZL —
DZL Characteristics SZL Characteristics
DZL is a water tube&fire tube boiler
smoke is in three pass
SZL is a double drum water tube boiler with
a convection tube between the upper and lower drums
The water wall tube and the lower part of the shell on
both sides of the furnace are radiation heating surfaces
The water wall tube around the furnace
as a radiation heating surface
Threaded pipe technology, featuring fast
heating and fast boosting
Adopt the "S" type to improve the heat transfer
system and reduce the wear of the heated surface
Compact structure, small size, easy to transport
and install, more suitable for under 8 tons
Large water volume, large furnace volume, stable,
safe and reliable, more suitable for large tonnage

Manual Coal/Biomass Boiler

The hand-burning boiler is the simplest combustion equipment in industrialboilers. Theoperations of adding coal, removing fire and removing slag are manually done by hands.

Simple equipment, low technical requirements, and can burn coal or biomass

Good fire conditions, fuel does not need to be crushed

Large amount of fuel can be stored in the furnace, the combustion is stable

Simple to install and consumes less power, reduce cost
