Oil and Gas Fired efficiency Boiler high quality unique design
large furnace low nitrogen oxide emission
Technical advantages
Unique structural design
It adopts the unique design of central back-firing and two-pass,
the center of the combustion chamber is arranged at a low position,
and the heat exchange flue pipe is symmetrically distributed on the
left and right.
The rational application of the corrugated furnace and the threaded
smoke pipe of the enhanced heat transfer element not only
strengthens the turbulent heat transfer of the high-temperature
flue gas, but also effectively absorbs the thermal expansion and
contraction of the furnace body.
The boiler adopts the design idea of large furnace, which burns
completely, is not easy to deposit carbon, has the characteristics
of high efficiency and sufficient output, and low nitrogen oxide
emission.
The economizer and condenser are arranged on the top of the boiler,
with compact structure and no floor space.
The economizer and condenser adopt the spiral finned tube type to
enhance heat transfer, and the countercurrent arrangement has good
heat transfer performance.
The condenser is made of special ND steel, which has good corrosion
resistance to condensed water and greatly improves the service
life.
Reasonable flue structure, smoke box hydrophobic structure,
condensed water is easy to discharge, collect and process.
Energy saving and environmental protection
The boiler adopts the design idea of large furnace to reduce the
heat load of the furnace volume. With professional burners, the NOx
emission is as low as <30mg/Nm³.
99% of the composition of natural gas is methane (CH4), which
contains a large amount of hydrogen (H). The flue gas after
combustion contains a large amount of water vapor. According to
theoretical calculations, the proportion of water vapor in the flue
gas is about 18%. If the water vapor is condensed into water and
the latent heat of vaporization is recovered, about 5% of the heat
is recovered, and the boiler efficiency can be increased to >
100%.
