Abstract

The utility model discloses a vertical energy-saving atmospheric heating boiler. The utility model is composed of a boiler shell body, a boiler container, an upper combustion chamber, a lower combustion chamber, etc. The lower part of the lower combustion chamber is fixed with a fixing fire grate. The lower part of the boiler container is provided with a water cooling fire grate. The boiler container is longitudinally distributed with fire pipes. The upper end and the lower end of the fire pipe are respectively communicated with the upper combustion chamber and the lower combustion chamber. The upper end of the fire pipe is buckled with a hat type fire combusting sieve. The utility model causes the combusting coal to be sufficiently combusted through the secondary combustion, improves the utilization rate of the combusting coal, reduces the dust concentration and the discharge of the harmful gases, saves the energy source, and protects the environment.

Description

Vertical energy-saving normal pressure heating boiler

The utility model relates to a kind of heating boiler, particularly a kind of vertical energy-saving normal pressure heating boiler.

The common vertical normal pressure heating boiler that provides in the market, it is little to have floor space, easy for installation, never Bao Zha characteristics.But because its combustion journey is short, fuel combustion is insufficient, and combustion gas is directly arranged to flue, and efficiency of combustion is low, and over-emitting black exhaust has caused serious pollution to environment, has also wasted the energy simultaneously.

The purpose of this utility model just is to provide a kind of vertical energy-saving normal pressure heating boiler that can improve efficiency of combustion through second-time burning.

Technical solution of the present utility model is: flue is separated into upper combustion chamber and lower combustion chamber's two parts with burner hearth, bottom in lower combustion chamber is fixed with fixed grate, bottom at flue is provided with water-cooled grate, be vertically arranged with fire tube on the flue, the upper and lower end of fire tube is opened on respectively in upper combustion chamber and the lower combustion chamber, in the upper end of fire tube spiral-lock fire combustion sieve is arranged; In upper combustion chamber, be provided with horizontal water tube.

Cap structure is sieved in the fire combustion, is become with the porous screen banks by fire combustion screen frame (unit), and the porous sieve places on the fire combustion screen frame (unit), is processed with secondary wind inlet on the fire combustion screen frame (unit).

The utility model reasonable in design is skillfully constructed, and can make fire coal carry out second-time burning in stove, and fire coal is fully burnt, and has improved efficiency of combustion, has reduced dust concentration and harmful gas emission; Owing to enlarged heat exchange area, improved the thermal efficiency of boiler simultaneously.It is little that the utility model had both had floor space, and characteristics easy for installation have the advantage that can reduce environmental pollution and energy savings again.

Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.

Fig. 1 is the structural front view of partly cuing open of the present utility model;

Fig. 2 is that structure of the present utility model is analysed and observe left view;

Fig. 3 is the structure sectional plan view of the utility model moderate heat combustion sieve;

Fig. 4 is the elevational schematic view of fire combustion sieve structure.

With reference to accompanying drawing, the utility model mainly is made up of boiler shell 2, flue 15, and flue 15 is separated into upper combustion chamber 17 and lower combustion chamber's 12 two parts with burner hearth, and the bottom of lower combustion chamber 12 is fixed with fixed grate 7; Be provided with the water-cooled grate 6 of inclination in the bottom of flue 15; The superjacent air space of water-cooled grate 6 is coal chambers 14, vertically is furnished with fire tube 5 on flue 15 equably, and the upper and lower end of fire tube 5 is connected with upper combustion chamber 17 and lower combustion chamber 12 respectively; The upper end spiral-lock of fire tube 5 has the fire combustion sieve 4 of cap structure, and fire combustion sieve 4 adopts refractory material to make, and it is made up of fire combustion screen frame (unit) 41 and porous sieve 42, and porous sieve 42 places on the fire combustion screen frame (unit) 41, is processed with secondary wind inlet 43 around fire combustion screen frame (unit) 41; The longitudinal and transverse horizontal water tube 3 that is provided with alternately in upper combustion chamber 17.The recirculated water that heating is used is housed in the boiler shell 2, water also is housed in water-cooled grate 6, horizontal water tube 3 and the flue 15 and is communicated with water in the boiler shell 2.

Be respectively arranged with lower furnace door 10, coal chamber door 13 and adjustable upper furnace door 16 on boiler shell Z, it is heavy that upper furnace door 16 can be regulated air intake according to combustion case; On lower furnace door 10, also be provided with peep hole 11, be used for observing, understanding combustion position.Water level meter 18 is arranged on the top of boiler shell 2, and internal water what are used to show.In order to make full use of waste heat, the water that is outside equipped with in bathing water tank 1 water tank at the flue 19 of upper boiler is not communicated with water in the boiler shell 2.Flue gas can utilize waste heat with the heating of the water in the bathing water tank 1 when discharging.

The utility model can place boiler on the pedestal 8 in use, and ash door 9 is set.

Coal is added by the coal chamber, is added in above the water-cooled grate, and flame is anti-downwards to be burnt, and coal chamber door is in open mode during burning.The scorching hot red carbon granule that does not burn falls into and continues on the following fixed grate upwards just to burn, and adjusts the aperture of coal chamber door and ash door and can regulate fired state.Combustion gas in the lower combustion chamber flows to hat type fire combustion sieve through fire tube, do not fire fuel gas such as carbon monoxide, carbon dioxide etc. and small grain size carbon granule run into high temperature red heat in upper combustion chamber fire combustion sieve in the combustion gas, add that the fresh air effect that enters from adjustable upper furnace door carries out second-time burning, make full combustion of fuel, last flue gas is discharged from flue 19.Through above-mentioned combustion process, improved the utilization rate of coal, improved efficiency of combustion, make that dust concentration and pernicious gas significantly reduce in the flue gas, protected environment.

Combustion gas is carried out sufficient heat exchange with boiler shell inwall, fire tube wall and horizontal water tube wall in discharge process, water, the water in the flue and the water in the horizontal water tube in the boiler shell are heated up.Direction shown in the arrow is the flow direction of water among the figure.
