Abstract

The utility model discloses a controllable internal ventilating combustion-supporting energy-saving boiler. A boiler body is a water sleeve sandwich layer, an upper and a lower two combustion chambers are arranged in the boiler body, the two combustion chambers are communicated by a flue, and the upper part of the lower combustion chamber is provided with a secondary wind device; the secondary wind device forms the cylinder shape or the round table shape, wind inlets are arranged on the bottom of the secondary wind device, and many secondary wind holes are uniformly arranged on the four walls of the four walls; water pipes which are communicated with a water sleeve are transversely arranged on the upper combustion chamber. The utility model can make the combustion more sufficient. The discharge of the carbon monoxide and the carbon particles is reduced, the heating efficiency of the boilers is improved, and the environment is protected.

Description

Controllable type inner ventilation combustion-supporting and energy-saving boiler

The utility model relates to a kind of hot-water boiler.

Normally used vertical type water heater boiler, body of heater are water jacket samdwich, are provided with the combustion chamber in body of heater inside, and top is provided with chimney, because coal-burning boiler only ventilates in the bottom, incomplete combustion has a large amount of carbon monoxide and carbon granule in the flue gas.

The purpose of this utility model is to give wind apparatus for coal-fired vertical type water heater boiler design secondary, by combustion-supporting heat release, improves boiler thermal output, reaches energy saving purposes, helps protecting environment simultaneously.

Technical scheme is as follows:

The vertical boiler body of heater is a water jacket samdwich, is provided with upper and lower two combustion chambers in body of heater, is connected by flue between two combustion chambers, and the transversely arranged water pipe that is connected with water jacket is housed in the upper combustion chamber; On the top of lower combustion chamber an overfire air device is housed, overfire air device is cylinder or truncated cone-shaped, is provided with air inlet in the bottom, has equally distributed secondary air hole at the wall of overfire air device.

The wall of overfire air device is equipped with the water pipe of the vertical arrangement that is connected with water jacket, and inwall is equipped with liner plate, at liner plate outside filling fire resisting material.

The utility model has the advantages that: the overfire air device design, by helping oxygen burning heat release, improve boiler thermal output, energy-conservation, consumption reduction helps environmental protection.

Further specify below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model overfire air device A-A sectional drawing.

In the drawings, body of heater is a water jacket samdwich 2, on water jacket, under be respectively equipped with the supplying drainage interface, be provided with upper combustion chamber 9 in the body of heater, lower combustion chamber 10, the horizontally-arranged pipe that is connected with water jacket is housed in the upper combustion chamber, the top is provided with chimney 1, the lower combustion chamber bottom is a grate, and the side has fire door, and an overfire air device is equipped with on top, on, lower combustion chamber is communicated by flue 3, flue is two parts, is the annular flue that is formed by water jacket and overfire air device below, and top is the smoke exhaust pipe that one group of pipeline of vertically arrangement is formed, the overfire air device profile is a truncated cone-shaped, the bottom is an air inlet 4, as can be seen from Fig. 2, liner plate 5 is arranged in the wall of round platform, the secondary air hole 6 that the outside is evenly distributed, the water pipe 7 of the vertical arrangement that is connected with water jacket and the refractory material 8 of filling.

In use, coal burns in lower combustion chamber, and flue gas rises, secondary wind mixes rising with flue gas at annular flue, further burns in upper combustion chamber, makes like this that carbon monoxide and carbon granules reduce in the flue gas of discharge, at ventilating opening 4 places one typhoon machine is installed, is adjusted intake as required.
