Abstract
The utility model relates to a vacuum phase transition moving hearth used in an ordinary pressure boiler. A plurality of water pipe grates which are shaped, and an inner and an outer shells of the hearth are welded mutually into integration to form a vacuum phase transition chamber. The lower part of the phase transition chamber contains definite liquid and the upper part is provided with a heat exchange coil pipe which is welded with one side of the outer shell. The front of the hearth is welded with a furnace door frame, a coal feeding door and a wind regulating board. The top and the bottom of the back of the hearth are respectively welded with a liquid replenishing joint and a vacuum pumping joint which is used for loading valves.
Description
The utility model is a kind of technological improvement that is used for the normal-pressure boiler burner hearth.Be specifically related to a kind of phase transition of vacuum travelling oven hall.
The vast town and country of China also are being extensive use of the boiler for domestic of the raw coal that burns, for reaching the purpose of smoke abatement and dust control, most of stove and accessory has adopted double-layer grate counter-burning type structure, smoke medicining dust-removing effect is good, but the back-burning boiler with double-layer fire grates water pipe furnace grate exists easy fouling, the major defect that life-span is short has hindered promoting the use of of this stove and accessory.
The utility model provides a kind of phase transition of vacuum movable burner hearth, and it has kept the advantage of the anti-sintering structure of double grate, and has solved the easy fouling of water pipe furnace grate, and the defective that the life-span is short has prolonged service life of boiler, has improved the thermal efficiency.
To achieve these goals, heat exchanger coil is equipped with on the top of the utility model between the inside and outside shell of burner hearth of welding mutually, the water-in and water-out joint of this coil pipe is connected up and down with a side of furnace enclosure, the water pipe furnace grate that lower furnace portion does not have is welded on respectively on the front and rear panel of burner hearth inner casing, after making the weldering of inside and outside shell and water pipe furnace grate for one, constitute the phase transition of vacuum chamber, the bottom of phase transition of vacuum chamber fills the liquid of some.The front of the movable burner hearth of phase transition of vacuum is welded with firedoor frame, and firing door and air regulating board are housed, and the burner hearth back is welded with vacuumizing joint and fluid infusion joint.
The utility model is used for that following characteristics are arranged behind the normal pressure boiler for domestic:
1, thermal efficiency height owing to adopted the phase transition of vacuum technology, has fallen at the end vaporizing liquid temperature, has improved heat transfer efficiency.Simultaneously, rationally transfer wind by the air regulating board that is provided with after, make burning more complete, thereby improved the thermal efficiency.
2, never fouling because of the indoor liquid of phase transition of vacuum, is the evaporation that goes round and begins again all the time, and condensation process liquid never consumes, and has formed the never condition of fouling.
3, long service life because scaling not in the movable burner hearth of phase transition of vacuum, has prevented the mistake cause thermal damage of furnace grate tube, has prolonged the service life of boiler.
Fig. 1 is a structural representation of the present utility model
Below in conjunction with accompanying drawing the utility model embodiment is further described.
By shown in Figure 1, furnace enclosure (5) and burner hearth inner casing (6) weld after being shaped and are one, and the two ends of water pipe furnace grate (3) are welded on respectively on the front and rear panel of burner hearth inner casing.Space after inside and outside shell and water pipe furnace grate weld has mutually formed phase transition of vacuum chamber (10).Bottom, phase transition of vacuum chamber fills the liquid (2) of some, and heat exchanger coil (7) is equipped with on top, and the import and export joint (9) of this coil pipe, (8) are welded on next side that goes up of shell respectively.The burner hearth front is welded with firedoor frame (13), and firing door (12) and air regulating board (11) are housed.The burner hearth back is welded with vacuumizing joint (4) and the fluid infusion joint (1) that the dress valve is used.
During use, on existing normal-pressure boiler, make a mount pad, in the seat of then this burner hearth being packed into, and connect heat exchanger coil Inlet and outlet water joint by these burner hearth overall dimensions.Can use by the anti-method of operating of burning stove of double grate.
Claims (2)
1, a kind of by furnace enclosure (5), burner hearth inner casing (6), water pipe furnace grate (3), the movable burner hearth of the phase transition of vacuum that heat exchanger coil (7) etc. are formed, it is characterized in that: heat exchanger coil (7) is equipped with on the top between movable furnace enclosure (5) and the burner hearth inner casing (6), advancing of this coil pipe, water out adapter (9), (8) divide next side that goes up that is welded on shell in addition, the two ends of the water pipe furnace grate that lower furnace portion is provided with (3) are welded on respectively on the front and rear panel of burner hearth inner casing, in, shell and water pipe furnace grate weldering are one, constitute phase transition of vacuum chamber (10), the bottom of this phase transformation chamber fills the liquid of some (2).
2, the movable burner hearth of phase transition of vacuum according to claim 1 is characterized in that: connecting firing door (12) and air regulating board (11) on the firedoor frame (13) that movable burner hearth one face down bonding has; Opposite side is welded with fluid infusion joint (1) and vacuumizing joint (4).
