Description

Energy-efficient heating furnace

The utility model relates to a kind of heating furnace, particularly relates to a kind of energy-efficient heating furnace.

Heating furnace is in oil field gathering and transportation technology, it is a visual plant, it is mainly used in the technological processes such as heating crude oil dehydration, the crude oil heater collection is defeated, the heating crude oil pipe is defeated, and existing heating furnace heating surface arrangement areas is few, the thermal efficiency is low, only reach 65%, the flue diameter is less, and the flue surface thermal load is bigger, easily cause the flue bulge to be broken, the exhaust gas temperature height, at 300-500 ℃, heat loss due to exhaust gas is big, because heated furnace volume is little, in service will many heating furnaces, power consumption is big, has strengthened operating cost.

The purpose of this utility model is, for overcoming the deficiency of prior art, provides a kind of capacity big, and the surface of burner hearth thermic load is low, thermal efficiency height, energy-efficient heating furnace simple in structure.

Following mode can realize the utility model:

Energy-efficient heating furnace comprises shell, burner hearth, front smoke box and entery and delivery port, and major diameter burner hearth and minor diameter flue are connected in series in the shell, and the rear portion of minor diameter flue connects rear smoke chamber, and many smoke pipes form tube bank and connect rear smoke chamber and front smoke box.

The minor diameter flue is a bellows.

The utility model major diameter burner hearth has enough big space can supply fuel completing combustion, furnace heat release and surface of burner hearth thermic load are lower, can not produce burner hearth wall overheating deforming, bellows minor diameter flue has solved the problem of burner hearth, flue expanded by heating, this heating furnace adopts many smoke evacuation tube banks, it is long-pending to have strengthened convection heating surface, the heating furnace exhaust gas temperature is low, the thermal efficiency can reach about 90%, cuts down the consumption of energy the flue gas flow rate height, smoke pipe is dust stratification dirt not, alleviate heating furnace and safeguard intensity, this heating furnace structure is simple, but both normal pressure operations.The design of also can gaining in strength moves under 0.4MPa pressure, and heating working medium can be former water, oil-polluted water or former wet goods.

Fig. 1 is a heating furnace overall structure schematic diagram.

Fig. 2 is the A-A cutaway view of Fig. 1.

Embodiment:

The front portion is provided with burner hearth 4 in the heating furnace shell 1, burner hearth 4 diameter phi 2000mm, the burner hearth 4 rear portions minor diameter bellows flue 5 that is connected in series, flue 5 rear portions are connected with rear smoke chamber 6, and many smoke pipes 7 form tube bank, connect rear smoke chamber 6 and front smoke box 9, front smoke box 9 connects chimney, 8 is shell front heads among the figure, and water inlet pipe 3 enters in the shell from shell 1 rear portion, and 2 is shell 1 supporting seats among the figure.Running: this heating furnace is a forced burning, air blast makes air before entering burner hearth 4, enter air register 10, in burner 11, fully mix back fully burning in burner hearth 4 with fuel, high-temperature flue gas enters rear smoke chamber 6 by minor diameter flue 5, enters front smoke box 9 by smoke pipe bundle 7 again, enters chimney from front smoke box 9 again, water enters shell 1 bottom from water inlet pipe 3, after being heated, the dividing plate 12 among Fig. 1 only allows the water after heating overflow from top, extract out by delivery port 13, this is to move under normal pressure, and bellows minor diameter flue 5 can effectively solve burner hearth 4 expanded by heating problems, select higher velocity of flue gas for use, make not dust stratification of smoke pipe bundle 7, needn't carry out smoke pipe and purge, this heating furnace is after increasing its Intensity Design, can move under the pressure of 0.4MPa, it is heated working medium also can be oil-polluted water, former wet goods.

Claims (3)

1, a kind of energy-efficient heating furnace, comprise shell, burner hearth, front smoke box and entery and delivery port, it is characterized in that: major diameter burner hearth and minor diameter flue are connected in series, and the rear portion of minor diameter flue connects rear smoke chamber, and many smoke pipes form tube bank and connect rear smoke chamber and front smoke box.

2, heating furnace according to claim 1 is characterized in that: the minor diameter flue is a bellows.
