Abstract

The utility model provides a vertical atmospheric hot-water boiler, relating to a vertical hot-water boiler, and the utility model is mainly designed for solving the problems that fume in a boiler liner of the existing boiler has dispersive flame, oxygen lack, insufficient combustion, etc. The utility model has the main method that a boiler arch is arranged in the boiler liner, the center of the boiler arch is provided with an opening used as a flame channel of the fume, and the lower part of the outer side of a boiler casing is provided with a secondary air device. The utility model has the advantages of concentrated flame of the fume, good air supply, sufficient combustion to fuel, high thremal efficiency and little envirimental pollution.

Description

Vertical normal-pressure hot-water boiler

The utility model relates to a kind of vertical type water heater boiler.

Existing vertical normal-pressure hot-water boiler fuel is not concentrated at flue internal combustion flue gas flame, anoxic in addition, and it is insufficient to burn, and the thermal efficiency is low, and environmental pollution is also heavier.

The purpose of this utility model is that a kind of flue gas flame of design is concentrated, and fuel can fully be burnt, and improves the vertical normal-pressure hot-water boiler of the thermal efficiency and minimizing environmental pollution.

Another purpose of the present utility model is a kind of vertical normal-pressure hot-water boiler that can increase oxygen supply to smoke combustion of design.

Solution is as follows: be flue 5 in the boiler furnace shell 3, there is stovepipe 1 the flue top, straight horizontal water tube 4 is arranged at flue top, and there is fire grate 9 the flue below, and there is fire door 8 the fire grate top, there is hand hole door 6 top of fire door, establish chimney arch 7 in our flue in the middle of fire door and hand hole door, chimney arch is circular, makes of refractory material, the chimney arch outer rim is fixed on the inboard wall of furnace, and the opening of chimney arch central authorities is flue gas fire combustion passages.

In order to help fuel in the flue internal combustion, increasing oxygen supplies with, we establish overfire air device 10 in the outside, furnace shell bottom, its lower end has air inlet 17 to communicate with air channel, flue bottom, the upper end has overfiren air port 18 to lead in the flue of fire grate top, and the relative flue center line of overfiren air port has certain angle, so that mix in the same seasonal flue gas rotation that blows into fresh air oxygenation, it is more abundant to burn, and establishes the air quantity adjustment doors on the overfire air device.

The utility model has the advantages that: owing to there is chimney arch that flue gas flame is concentrated, ignition temperature is improved, make the combustible sufficient combustion, directly air feed in the combustion of flue gas fire of overfire air device is arranged in addition, so burning is just more abundant, has not only improved the thermal efficiency but also has reduced environmental pollution.

Fig. 1 is the schematic diagram that partly cuts open of the present utility model;

Fig. 2 is that A of the present utility model is to schematic diagram.

Among the figure; 1, stovepipe; 2, end socket; 3, shell; 4, straight horizontal water tube; 5, flue; 6, hand hole door; 7, chimney arch; 8, fire door; 9, fire grate; 10, overfire air device; 11, Hui Men; 12, atmospheric communicating pipe; 13, overflow pipe; 14, water tank; 15, blower fan; 16, blow-off pipe; 17, air inlet; 18, overfiren air port; 19, hot water outlet; 20, water inlet.

Embodiment: utilize existing vertical normal-pressure hot-water boiler, we make chimney arch 7 with refractory cement between fire door and hand hole door, the plate of containing dish that does not have the end that chimney arch shape such as left-hand thread, and its outward flange sealing and fixing is on inboard wall of furnace, and central authorities are openings; The overfire air device in the outside, furnace shell bottom is a flute profile air channel, its lower end is established air inlet 17 and is communicated with air channel, flue bottom, establish in the flue that overfiren air port 18 leads to fire grate top the upper end, and the angle of the direction in air port 18 and flue center line (being the lead-in wire that passes through the flue center of circle of horizontal direction) is 24 °.Establish air quantity adjustment doors (establishing plate gets final product) at air inlet 17 and overfiren air port 18 places.
