Novel full premix silicon cast aluminium condensing boiler

Technical field

The utility model belongs to boiler plant technical field, and in particular to a kind of novel full premix silicon cast aluminium condensing boiler.

Background technique

Known, boiler is a kind of energy conversion, and the energy inputted to boiler has chemical energy, electric energy in fuel, pot Furnace output has steam, high-temperature water or the organic heat carrier of certain thermal energy.In order to improve the thermal conversion efficiency of boiler, go out on the market A kind of cast iron gas fired-boiler is showed, such boiler is formed in furnace body by the way that heating column is arranged in furnace interior by heating column Flow-guiding channel, so as to improve heat exchange efficiency.

But such cast-iron boiler is in actual use, still has certain drawbacks, is mainly reflected in 1. Water conservancy diversion column density around combustion chamber is big, and combustion chamber ambient heat can not be quickly mobile to other positions, leads to combustion chamber Ambient temperature is significantly larger than other positions, and heat loss is not thorough；2. boiler internal, the position far from combustion chamber is easy in water conservancy diversion Occurs condensed water on column, but furnace interior is sealing, and quickly condensed fluid can not be discharged, for a long time using being easy to cause Radiating efficiency reduces and easily corrodes furnace interior, reduces the service life of furnace body；3. existing cast-iron boiler can not with it is outer Portion premixes blower connection entirely, can only be used by conventional combustion system, high in the gas nitrogen content that exhaust end is discharged, nothing Method reaches current environmental requirement.

How to be improved by technology for the drawback in the prior art as the technical staff of the industry, is designed a kind of new The full premix silicon cast aluminium condensing boiler of type, makes it in the structure basis of current cast-iron boiler, not only can effectively improve Its heat exchange efficiency can also effectively prevent its internal condensation liquid from retaining, furthermore, it can connect, have with external premix blower The efficiency of combustion of the raising boiler of effect.

Utility model content

As the technical staff of the industry, open this programme the technical problem to be solved is that how on boiler structure weight New design on the basis of every advantage of current cast-iron boiler, is allowed to effectively by designing new structure of boiler body Raising boiler radiating efficiency, avoid internal condensation dilutional hyponatremia and the corrosion phenomenon that occurs, and combustion can be effectively reduced Nitrogen discharge amount during burning.
