Abstract

The utility model relates to a vertical coal-fired hot-water boiler. The utility model is technically characterized in that the vertical coal-fired hot-water boiler is provided with a water jacket layer formed by a housing and a boiler liner which are connected, a hanging liner with a smoke-fire pipe and a heat pipe and a water cooling pipe row, and a primary air system is installed under a fire grate on which a secondary air system obliquely penetrating through the wall of the boiler liner is arranged. The vertical coal-fired hot-water boiler has the characteristics of whirlwind type combustion, superconductive heat transfer, high heat efficiency and small size, the smoke pollution achieves the national standard, and therefore, the utility model meets the operating requirements of vegetable greenhouses.

Description

The vertical fire coal hot-water boiler

The utility model relates to a kind of hot-water boiler of heating.

In recent years, the hot house of winter planting vegetables has been popularized northern country, uses various civil arcola heating in the booth, because the arcola smoke contamination is more serious, flue dust falls back to above the hot house, damages plastic foil easily or influences the glory effect.Also because the heat insulating ability of booth is poor, the temperature of the heating area green house of vegetables that same boiler is same is starkly lower than other facility.

The purpose of this utility model provides a kind of vertical, normal pressure, hot-water boiler, and it has, and the little thermal power of volume is big, efficient is high, thereby the good characteristics of smoke medicining dust-removing effect satisfy the instructions for use of green house of vegetables.

The technical solution of the utility model is: a kind of vertical fire coal hot-water boiler, has boiler jacket, flue, fire grate, hang courage, water leg layer in the middle of boiler jacket and flue are connected to form at the edge, hanging courage is communicated with the water leg layer by some connecting legs, wind system once below the fire grate, there is secondary air system combustion chamber above the fire grate, it is characterized in that: hang on the bottom surface of courage and install some heat pipes, one end of heat pipe places in the combustion chamber, the other end places and hangs in the courage, hang and also have some pyrotechnics pipes to pass through in the courage, the wind that installs secondary air system on the furnace wall is chewed, the axial line that its wind is chewed along stretching, overlaps with a concentrically ringed tangent line of combustion chamber in the combustion chamber, and secondary wind is chewed with hanging and the water cooling tube that two ends are communicated with the water leg layer is housed between the courage is arranged.

Other structure of this boiler is identical with common vertical fire coal hot-water boiler.

Because the secondary wind energy that present technique provides produces the air-flow of rotation in the combustion chamber, wind is air feed from bottom to top, and wind and secondary wind can impel the flue gas rotation upwards to enter chimney together.This cyclone type burning can make air fully contact with fuel, flame and flue gas stroke in stove prolongs, the time that stops increases and the chance of full combustion of fuel is provided, therefore this boiler has reduced the concentration of smoke evacuation dirt, reached the index of national regulation, reduced flue dust and carried out the harm of covering booth and damage plastic foil.Present technique adopts the heat pipe super heat conduction at the main heat-transfer area of boiler, makes boiler heating rapid, energy savings.The water space capacity of boiler is the water leg layer, hang courage and water cooling tube row, and their common feature is the big thin water layer structure of heating surface, and the flue gas helical form is washed away thin water layer, so the heat transfer efficiency height, and thermal cycle is fast.In green house of vegetables, use and to overcome the shortcoming that existing boiler exists.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the structural representation of the utility model vertical fire coal hot-water boiler.

Fig. 2 is the A-A profile of the utility model Fig. 1.

Fig. 3 is the B-B profile of the utility model Fig. 1.

Among the figure, the shell of boiler (5) bottom is provided with coal feeding hole (10).Shell (5) and the welding of flue (4) two edges, the middle uniform annular water leg layer (1) that forms.Water leg layer (1) bottom is communicated with return pipe (14), and top is communicated with outlet pipe (13), and thermometer (18) is housed near the outlet pipe.The inner combuster of flue (4) (19), the top of combustion chamber (19) have water cooling tube row (7), and each port of pipe row (7) is communicated with water leg layer (1).Courage (3) is hung in water cooling tube row's (7) top, and this hangs conduit (2) and the conduit (6) of bottom of courage by the top and is communicated with respectively with water leg layer (1) and fixes.Hang on the bottom surface of courage and install heat pipe (15), an end of every heat pipe (15) places the combustion chamber, and the other end places and hangs in the courage, and heat pipe one end can conduct to the other end with heat rapidly after the combustion chamber is heated, and the water that hangs in the courage is heated up rapidly.Also have 5 pyrotechnics pipes (16) in hanging courage (3), to pass through.Supply air system is distributed to an airduct (11) and secondary air channel (9) by blower fan by bellows (12), airduct places below the fire grate (17), the main body of secondary air channel is by the water leg layer, wind is chewed (8) and is tiltedly worn furnace wall, the tangent line of the circle that the axial line that wind is chewed (20) and combustion chamber are concentric overlaps, being evenly distributed with 4 secondary wind on the furnace wall chews (8) they blows simultaneously and form rotation air-flow upwards with a wind that directly blows in the combustion chamber, air is fully contacted with fuel, make full combustion of fuel, the stroke of flame and flue gas is prolonged.The utility model boiler adopts the cyclone type supply air system, cooperate the courage that hangs that has super heat conduction in the body of heater of thin water layer and the body of heater, make this boiler have that volume is little, to start heat supply rapid, thermal efficiency height, therefore the characteristics that smoke contamination is little have satisfied and used needs in green house of vegetables.

Claims (1)

1, a kind of vertical fire coal hot-water boiler, has boiler jacket, flue, fire grate, hang courage, water leg layer in the middle of boiler jacket and flue are connected to form at the edge, hanging courage is communicated with the water leg layer by some connecting legs, wind system once below the fire grate, there is secondary air system combustion chamber above the fire grate, it is characterized in that, hang on the bottom surface of courage and install some heat pipes, one end of heat pipe places in the combustion chamber, the other end places and hangs in the courage, hang and also have some pyrotechnics pipes to pass through in the courage, the wind that installs secondary air system on the furnace wall is chewed, the axial line that its wind is chewed in the combustion chamber along stretching, overlap with the tangent line of the concentric circle in combustion chamber, secondary wind is chewed with hanging the water cooling tube row that two ends are communicated with the water leg layer is housed between the courage.
