Abstract
The utility model provides a thermal oil furnace with common heat sources of high temperature flue gas and fuel gas. The thermal oil furnace comprises a gas burner, a hearth, a smoke vent, a conduction oil inlet, a furnace pipe and a conduction oil outlet. The thermal oil furnace further comprises a high temperature flue gas inlet pipe which can lead rotary kiln high temperature flue gas into the hearth. The furnace pipe is located in the hearth. The conduction oil inlet, the furnace pipe and the conduction oil inlet outlet are connected in sequence. The smoke vent is communicated with the hearth. The gas burner puts the fuels into the hearth. The high temperature flue gas inlet pipe is connected with a rotary kiln and the hearth. The thermal oil furnace with common heat sources of the high temperature flue gas and the fuel gas takes full advantages of rotary kiln high temperature flue gas waste heat to solve heating limits of single fuel (fuel gas). When the rotary kiln is in a state of outage, the fuel gas can be used for the fuel of the thermal oil furnace to supply heat for thermal equipments. After the rotary kiln is in operation, the rotary kiln high temperature flue gas is the main fuel and the fuel gas is the auxiliary fuel.
Description
Technical field
The utility model relates to a kind of heat-conducting oil furnace, is specifically related to a kind of heat-conducting oil furnace take high-temperature flue gas and combustion gas as common thermal source.
Background technology
Organic heat carrier furnace claims again heat conducting oil boiler, mainly is comprised of burner, burner hearth, exhaust opening, heat conductive oil inlet, boiler tube, conduction oil delivery outlet, take coal, oil, combustion gas as fuel.Fuel fully burns at burner hearth and forms flame and high-temperature flue gas, with conduction oil heat exchange in the mode of radiant heat transfer and convection heat transfer' heat-transfer by convection and the boiler tube, conduction oil realizes forcing closed cycle by oil circulating pump in system, simultaneously, the conduction oil that obtains heat in body of heater is extremely used hot equipment as the heat transferring medium heat supply, thereby realizes the heat supply of heat-conducting oil furnace heating system.
In the needle coke production process, have simultaneously rotary kiln and heat-conducting oil furnace, rotary kiln is as needle coke calcination equipment, and heat-conducting oil furnace utilizes the high-temperature flue gas of rotary kiln as the shared heating equipment in the needle coke production technology, has reached energy-saving and cost-reducing purpose.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of heat-conducting oil furnace take high-temperature flue gas and combustion gas as common thermal source, and it can recycle the heat energy of rotary kiln high-temperature flue gas.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind ofly comprise gas burner, burner hearth, exhaust opening, heat conductive oil inlet, boiler tube, conduction oil delivery outlet take high-temperature flue gas and combustion gas as the heat-conducting oil furnace of common thermal source, also comprise the high-temperature flue gas inlet tube of the rotary kiln high-temperature flue gas being introduced burner hearth; Boiler tube is positioned at burner hearth, and heat conductive oil inlet, boiler tube and conduction oil delivery outlet connect in turn, and exhaust opening and burner hearth are communicated with, and the high-temperature flue gas inlet tube connects burner hearth.
The utility model takes full advantage of rotary kiln high-temperature flue gas waste heat, has solved the limitation of single-fuel (combustion gas) heat supply.When rotary kiln is in shut down condition, use combustion gas as the fuel of heat-conducting oil furnace, give with hot equipment heat supply.Behind rotary kiln running, be main by the rotary kiln high-temperature flue gas mainly, take combustion gas as auxiliary fuel.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 boiler tube, 2 exhaust openings, 3 conduction oil delivery outlets, 4 high-temperature flue gas inlet tubes, 5 gas burners, 6 heat conductive oil inlets.
The specific embodiment
As shown in Figure 1, a kind of heat-conducting oil furnace take high-temperature flue gas and combustion gas as common thermal source comprises gas burner 5, burner hearth, exhaust opening 2, heat conductive oil inlet 6, boiler tube 1, conduction oil delivery outlet 3, also comprises the high-temperature flue gas inlet tube 4 of the rotary kiln high-temperature flue gas being introduced burner hearth.
The heat supply deficiency that the utility model can utilize combustion gas to replenish high-temperature flue gas, the heat energy demand when having solved start-stop car, abnormal operation, energy-saving and cost-reducing.
