Fig. 1 is a schematic diagram of the present invention.
Detailed Description
In order to explain the utility model more fully, the utility model provides an implementation example. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.
The invention is explained in further detail with reference to the drawings, in which the reference symbols are: 1: a furnace body; 2: a front smoke box; 3: a rear smoke box; 4, a furnace body smoke pipe; 5: a hearth; 6: a condenser; 7: a condenser flue tube; 8: a condenser smoke box; 9: a burner; 10: an inner barrel; 11: a smoke outlet; 12: a fan; 13: an air duct.
as shown in the attached drawings, a condensing boiler with a built-in burner comprises a boiler body 1, a burner 9, a condenser 6 and a fan 12, wherein the condenser 6 is fixedly connected and installed on the front wall of the boiler body, a condenser smoke tube 7 is arranged in the condenser, the condenser is of a structure with an inner tube 10 in the middle, the burner 9 is fixedly installed in the inner tube of the condenser, a hearth 5, a rear smoke box 3 and a front smoke box 2 are arranged in the boiler body, a boiler body smoke tube 4 is connected between the front smoke box and the rear smoke box, the inlet of the condenser smoke tube is communicated with the front smoke box 2 of the boiler body, a condenser smoke box 8 is arranged at the front end of the condenser, a smoke outlet 11 is arranged on the condenser smoke box, and smoke subjected to heat exchange is discharged out of the boiler through the smoke outlet; high-temperature flue gas formed by combustion in a hearth in the condenser sequentially passes through the rear smoke box, the furnace body smoke tube, the front smoke box, the condenser smoke tube and the condenser smoke box; the fan 12 is positioned at the upper part of the boiler, an air duct 13 in the vertical direction is arranged on the condenser, and the air duct is communicated to the combustor.
The condenser inner tube is placed in the boiler combustor of this structure in, and the fan is located the condenser top, sets up the wind channel between the barrel outside and in the condenser and lets wind get into the condenser inner tube, for the combustion of pressure-fired, the flue gas that produces after the burning gets into the furnace body tobacco pipe after the smoke box is collected, and the flue gas gets into preceding smoke box along furnace body tobacco pipe forward flow, gets into the condenser tobacco pipe after the smoke box mixes in the front, arrives the condenser tobacco box after the heat transfer, discharges along condenser outlet flue at last.
