Oil and Gas Fired efficiency Boiler high quality
The double-drum vertical D-type arrangement is adopted, and the
important pressure components such as the drum are not directly
protected by high-temperature flame radiation and erosion.
The boiler adopts the design concept 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 boiler adopts a self-supporting type structure, saving steel
frame and 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.
Large-scale assembly and supply, reducing the workload of on-site
installation.
The economizer and condenser can be placed on the upper part of the
boiler according to the site conditions.
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%.
