Description
Technical field
The utility model is related to machinery field more particularly to the low nitrogen condensation steam boilers of three backhaul of integral type.
Background technology
Because of characteristics such as steam self-temperature height so that current most of steam boiler exhaust gas temperatures are relatively high, Ge Bieda
To 200 °C or more.It is calculated with low heat valve, for efficiency often 90% or so, not only physical sensible heat waste is larger, but also high-order
The latent heat of vaporization of calorific capacity difference wastes completely, this not only consumes a large amount of energy, but also improves the operating cost of boiler.
The ingredient of natural gas is mainly based on C and H, and due to containing considerable H element, the steam vapour amount for generation of burning is larger, absorbs
A large amount of heat, thus the high calorific power of natural gas is higher than low heat valve by 10% or so, about 10% heat is steamed by water
Gas is taken away.If the exhaust gas temperature of boiler to be dropped to sufficiently low level.It will in the vapor of superheat state so in flue gas
It condenses into water and releases the latent heat of vaporization, the latent heat of vaporization in flue gas is enable to recycle.
