Description

A kind of energy-saving efficient boiler

Technical field

The utility model relates to a kind of power economized boiler, relates in particular to a kind of fire coal, fuel oil, combustion gas environment-friendly high-efficiency energy-saving boiler.

Background technology

Because exhaust gas temperature is higher, raising along with people's energy consciousness, utilization to the entrained heat of boiler smoke has proposed requirement, and existing boiler directly communicates with the boiler external world from burner hearth by mouth, chimney, the flue gas that causes the burner hearth fuel combustion to produce contains a large amount of heat energy fails effectively to utilize, and slatterns and be discharged in the atmosphere in vain.In addition, the flue gas of high temperature also can reduce the service life of chimney.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of waste heat in the flue gas is fully used, and improve the chimney boiler in service life.

Technical solution of the present utility model is:

A kind of energy-saving efficient boiler, comprise shell, flue, mouth, shell, flue surround water cavity, and the flue bottom is a burner hearth, and burner hearth one side is provided with mouth, on shell, be penetrated with first group of flue, first group of flue is at least 1 smoke pipe, is provided with first smoke box on the shell right side, and first smoke box and shell outer surface surround first smoke chamber, the right-hand member of mouth and first group of flue communicates by first smoke chamber, and first group of smoke pipe left end communicates with chimney.

A kind of energy-saving efficient boiler, comprise shell, flue, mouth, shell, flue surround water cavity, the flue bottom is a burner hearth, and burner hearth one side is provided with mouth, is penetrated with first group of flue and second group of flue on shell, first group of flue and second group of flue all are at least 1 smoke pipe, be provided with first smoke box on the shell right side, first smoke box and shell outer surface surround first smoke chamber, and the right-hand member of mouth and first group of flue communicates by first smoke chamber; Be provided with second smoke box in the shell left side, the outer surface of second smoke box and shell surrounds second smoke chamber, and the left end of second group of flue communicates by the left end of second smoke chamber with first group of flue, and second group of flue right-hand member communicates with chimney.

As improvement, in above-mentioned first smoke chamber, be provided with at least 1 endwall pipe, described wall pipe lower end is positioned at the lower end of mouth and communicates with water cavity, and described wall pipe upper end is positioned at the upper end of first group of flue and communicates with water cavity.

Technique effect of the present utility model is: because the utility model is penetrated with first group of flue on shell, make first group of flue pass water cavity, the right-hand member of mouth and first group of flue communicates by first smoke chamber, first group of smoke pipe left end communicates with chimney, therefore, the flue gas that contains a large amount of heat energy is by first group of flue the time, because flue-gas temperature is higher, heat in the flue gas is passed to water in the water cavity by first group of flue, on the one hand the heat in the flue gas is utilized effectively, the flue-gas temperature that enters chimney is reduced greatly, thereby improve the service life of chimney, therefore the utlity model has environmental protection, energy-efficient characteristics.In order to make the heat in the flue gas fully obtain utilizing, can also on shell, be penetrated with second group of flue and corresponding second smoke box; In first smoke chamber, be provided with the wall pipe.
