Abstract

The utility model relates to a double-chamber reciprocating-grate boiler which is on the basis of the existing reciprocating-grate boilers, belonging to heating boilers. A longitudinal furnace wall is additionally arranged in the hearth to divide a left hearth from a right hearth. Each hearth is provided with a fire grate respectively. A tube bank which is connected with a body is arranged on both side walls of the longitudinal furnace wall respectively. A curved-surface-shaped fully-enclosed left arch is arranged in the left hearth, and a slant-face-shaped fully-enclosed right arch is arranged in the right hearth. A left furnace burning-out chamber is communicated with a right hearth combustion chamber by a passage which is arranged at the back middle part of the longitudinal furnace wall, and the left furnace burning-out chamber is communicated with a right hearth burning-out chamber by a passage which is arranged at the front upper part of the longitudinal furnace wall. Besides, a left furnace combustion chamber is communicated with a right hearth combustion chamber by a passage which is arranged at the lower part of the longitudinal furnace wall. The boiler has the advantages that the boiler is suitable for inferior coal and reciprocating-grate boilers more than 10 tonnages.

Description

Double-chamber reciprocating-grate boiler

The utility model belongs to heating equipment boiler class.

Existing reciprocating-grate boiler is penetrated by fire grate and drive unit, the width of cloth and to be subjected to face body, convection current to be subjected to face body, slagging-off mechanism, insulation furnace wall, blower fan and air channel, what burner hearth and convection current formed by upright furnace wall, chimney arch in the burner hearth between the face body; This boiler can not burning low grade coal, can only adapt to fat coal; This boiler can not widely can only be suitable for below 10 tonnages because of fire grate, and fire grate easily can not normally be moved by scaling loss when above above 10 tonnages.

The purpose of this utility model is: provide a kind of can burning low grade coal and can adapt to the above twin furnace reciprocating-grate boiler of 10 tonnages.

Technical measures of the present utility model are: based on existing reciprocating-grate boiler; In burner hearth, add and put a vertical furnace wall, with burner hearth every being divided into left hearth and right bearth; A fire grate is arranged respectively in each burner hearth; Vertically be placed with tube bank on the furnace wall two side respectively with body UNICOM; The totally enclosed left chimney arch that a curved face type is arranged in the left hearth has the totally enclosed right chimney arch of a ramp type in the right bearth; The passage that left hearth burning chamber of UNICOM and right bearth combustion chamber are arranged at middle part, vertical furnace wall back; Have UNICOM's left and right sides burner hearth to burn the passage of cinder chamber in vertical furnace wall front upper, the passage of left and right sides fire box of UNICOM is arranged at the bottom.

Boiler of the present utility model adopts two fire grates of two burner hearths, makes single fire grate just narrow, is provided with vertical furnace wall in the burner hearth and passage is arranged, and increases the circuitous flow process of flue gas in burner hearth, so this boiler has the good effect that adapts to more than 10 tonnages and adapt to colm.

Fig. 1 is a front view of the present utility model, and Fig. 2 is a vertical view, and Fig. 3 is a right view.

1 is Pressure gauge among the figure; The 2nd, the width of cloth is penetrated and is subjected to face body (tube bank); The 3rd, the insulation furnace wall; The 4th, upright furnace wall; The 5th, convection current is subjected to face body (tube bank); The 6th, flue; The utility model adds in burner hearth puts a vertical furnace wall 21, is placed with the tube bank 22 with body UNICOM on its two side respectively; Vertically furnace wall with burner hearth every being divided into left hearth 19 and right bearth 20; A fire grate 13 is arranged respectively in the burner hearth of the left and right sides; The totally enclosed left chimney arch 9 that a curved face type is arranged in the left hearth 19 has the totally-enclosed right chimney arch 8 of a ramp type in the right bearth; Chimney arch 8 and 9 top are burning chamber, and the below is the combustion chamber; The passage that left hearth burning chamber of UNICOM and right bearth combustion chamber are arranged at the middle part, back 10 of vertical furnace wall 21; In the vertical front upper 7 of upright furnace wall 21 passage of left and right sides burner hearth burning chamber of UNICOM is arranged, the passage of left and right sides fire box of UNICOM is arranged at bottom 12; The combustible that does not burn in each fire box longitudinally passage on the furnace wall 21 is ganged up the circuitous cinder that makes it to burn, the structure of this boiler has increased the flow process of flue gas in burner hearth, the pollution that makes the circuitous fully burning of combustible and can adapt to colm and reduce to discharge.6 is flues among the figure, the 11st, and the drive unit of fire grate 13, the 18th, blower fan, the 14th, air channel, the 15th, skimming door, the 16th, access hole, the 17th, furnace bottom.
