Abstract

The utility model relates to a movable boiler of a fire bed with a complete cover rotational flow arch of a boiler, which belongs to the technical field of the boiler. The structure of the utility model is that the complete cover arch of the boiler which is fixed on the inner wall of the boiler of the fire bed is arranged on the space of the upper part of the movable fire bed; the edge of the arch of the boiler is fixed on the arch of the boiler of the coal entering end in the boiler to enable the arch of the boiler, the edge of the arch of the boiler and the inner wall of the boiler to form a cyclone cylinder type structure, and the outlet of the cyclone cylinder leads to a flue. The utility model has the advantages that cyclone firing area can be stably formed on the part of the head of the fire bed to intensify the convection effect and the radiation ignition effect, improve the flame fullness in the boiler, and enlarge the adaptability of the kind of the coal of the boiler of the fire bed.

Description

Moveable flame apparatus

The utility model belongs to boiler and heating furnace manufacturing technology field.

At present, one class such as chain furnace moves the grate stove, its critical component is a chimney arch, because it has decisive influence to the adaptability of efficiency of combustion and coal, and the conventional oven arch structure as shown in Figure 1, be made up of face arch and rear arch, this furnace arch structure poor performance of igniting only is suitable for burning than the above coal of high-quality.

The purpose of this utility model provides a kind of portable grate stove of all standing eddy flow furnace arch structure.

The utility model know-why is as follows:

Mobile grate 4 is arranged below the grate stove, fire coal 11 can be input to from coal bunker 10 and add gentle burning in the grate stove, at mobile grate 4 upper spaces, the all standing chimney arch 6 that is fixed on furnace wall or the boiler tube 12 is arranged, below the chimney arch 6 of in-furnace coal feeding end, be fixed with water conservancy diversion arch 5, make between chimney arch 6, water conservancy diversion arch 5 and the mobile grate 4 and form a whirlwind core structure, flue 9 is led in whirlwind tube outlet 2.To the stokehold burner hearth is divided into lower combustion chamber and top burning chamber behind the stove of chimney arch, this encircles by being made up of rear portion tilting section, middle part horizontal segment and anterior arc section successively to the stokehold behind the stove.Water conservancy diversion arch under the chimney arch is divided into primary zone, rear portion and anterior whirlwind tube combustion zone with the combustion chamber.The outlet of flue can be one-sided one, also can be two of bilaterals.

The utility model advantage is: it can form high temperature cyclone firing district in the grate head steady, has strengthened the double effects that convection current and radiation are ignited, and has improved the flame degree of filling in the stove, has enlarged the adaptability of the coal of grate stove.

Fig. 1 is that forward and backward arch formula moves grate furnace accretion composition;

Fig. 2 is the portable grate furnace accretion of an all standing eddy flow chimney arch composition;

Fig. 3 is the portable grate stove of an all standing eddy flow chimney arch A-A profile.

Wherein: the 1st, passage, the 2nd, the outlet of whirlwind tube, the 3rd, the whirlwind tube, the 4th, mobile grate, the 5th, console and fill arch, the 6th, chimney arch, the 7th, the combustion chamber, the 8th, burning chamber, the 10th, coal bunker, the 11st, coal-fired, the 12nd, furnace wall.

Mobile grate 4 is covered fully by chimney arch 6, burner hearth is divided into combustion chamber 7 and burning chamber 8 up and down by chimney arch 6, the head of mobile grate 4 encircles at water conservancy diversion and forms the horizontal cyclone combustion zone between 5 chimney arch 6 and the mobile grate 4, and the passage 1 that the high-temperature flue gas that the primary zone of combustion chamber 7 produces forms between chimney arch 5 and chimney arch 6 tangentially enters whirlwind tube 3 and produces an eddy flow.Flue gas is drawn from 3 outlets of whirlwind tube, tangentially enters burning chamber 8 through flue 9 from burning chamber's inlet, produces secondary eddy flow burning chamber inlet and can be located at stokehold side or rear side.

Claims (4)

1, the portable grate stove of a kind of all standing eddy flow chimney arch, by the furnace wall inwall, mobile grate is formed, and it is characterized in that at mobile grate upper space all standing chimney arch that is fixed on grate stove inwall being arranged, and is fixed with a furnace arch edge on the chimney arch of in-furnace coal feeding end.Make chimney arch, water conservancy diversion arch and stove inwall form a whirlwind core structure, and flue is led in the outlet of whirlwind tube.

2, the portable grate stove of all standing eddy flow chimney arch according to claim 1, it is characterized in that: to the stokehold burner hearth is divided into lower combustion chamber and top burning chamber behind the stove of chimney arch, this encircles by being made up of rear portion tilting section, middle part horizontal segment and anterior arc section successively to the stokehold behind the stove.

3, the portable grate stove of all standing eddy flow chimney arch according to claim 1 is characterized in that: the water conservancy diversion arch under the chimney arch is divided into primary zone, rear portion and anterior whirlwind tube combustion zone with the combustion chamber.

4, the portable grate stove of all standing eddy flow chimney arch according to claim 1, it is characterized in that: the outlet of flue can be one-sided one, also can be two of bilaterals.
