Abstract
The utility model relates to a heat-carrier heating furnace which adopts coal water slurry as flammable material and mainly burns the coal water slurry under a spray pattern. The utility model adopts coal water slurry for burning, so that the combustion efficiency is high, and the pollution is small, thereby having a practical significance in saving energy and reducing emission.
Description
Technical field
The utility model relates to the technical field of industrial combustion furnace, is a kind of heat medium heater of metabolic water coal slurry specifically.
Background technology
Our times; the big ups and downs of international petroleum price allow global people recognize that mondial energy crisis is extremely urgent; oil is as a kind of non-renewable energy resources; its reserves are quite few; be merely able to the mankind and exploited 30 years again, the clean energy resource of developing new alternative oil is very urgent.China is the quite abundant country of coal reserves, traditional coal-fired mode has caused serious atmosphere pollution, so coal liquefaction, vaporization and pulp become the research topic that industrially-advanced country generally payes attention to, water-coal-slurry then is the best achievement of coal liquefaction, also is the most cheap practical technique of coal clean utilization.Water-coal-slurry is that a kind of about 30% water and small amounts of medicament are mixed with the liquid that forms by about 70% coal dust, can be as oil pumping, atomizing, accumulating, and can be directly used in the burning of various boilers, kiln.It has changed the traditional combustion mode of coal, has demonstrated huge environmental protection and energy saving advantage.Especially in recent years, behind the technology path of employing changing waste into resources, the environmental protection water-coal-slurry of succeeding in developing can improve the environmental benefit of water-coal-slurry greatly under the prerequisite that does not increase expense.Under the guarantee of China's abundant coal data, water-coal-slurry has also become the optimal selection of clear energy sources such as substituting oil, gas.
Summary of the invention
The utility model is exactly a kind of heat medium heater that can the metabolic water coal slurry, as the water-coal-slurry that can substitute oil, have following a bit.
1. water-coal-slurry is made by 70% coal, 30% water and a small amount of chemical addition agent, and normal temperature keeps liquid condition down, can need not other preheating as oil pumping, atomizing, storage and smooth combustion;
2. water-coal-slurry has the concentration height, fine size, and good fluidity, the characteristics that efficiency of combustion is high, its efficiency of combustion can reach more than 98%, discharge-ring guaranteed cost height.
The utility model is horizontal cube structure, is made up of upper and lower two parts, and there is the chimney arch of " door " font body of heater inside, bottom, in the chimney arch is the combustion chamber, also has on the chimney arch flatly, is used to install water coal slurry burner, there are two mouthfuls on the water coal slurry burner, can feed atomized water coal slurry and air respectively; Top is the body of heater radiant section, the body of heater radiant section outside has two mouthfuls, one is the conduction oil inlet, another is the conduction oil outlet, connect with coil pipe between two mouthfuls, the body of heater radiant section connects ash dropping hopper near the below of conduction oil outlet, and there is mucking machine the ash dropping hopper below, and the ashes that burning produces can be discharged from mucking machine.
The course of work of the present utility model is such: feed the combustion chamber through water-coal-slurry and air after the atomizing respectively by two connectors on the water coal slurry burner, mix the back ignition in the combustion chamber, but heat that burning produces and the coil pipe in the flue gas heating furnace body radiant section, conduction oil in the coil pipe is flowed out by the conduction oil outlet after absorbing heat, release heat with hot equipment heat exchange the time, the conduction oil after the release heat can flow into the body of heater radiant section by the conduction oil inlet of body of heater radiant section and reheat.In the water-coal-slurry of combustion chambers burn, contain a spot of ashes in the flue gas of generation, assemble the back in the ash dropping hopper that can below the body of heater radiant section, connect and discharge by mucking machine.
Description of drawings
Fig. 1 is the utility model structural representation.
1 chimney arch, 2 combustion chambers, 3 water coal slurry burners, 4 body of heater radiant sections, 5 conduction oils inlet, 6 coil pipes, the outlet of 7 conduction oils, 8 ash dropping hoppers, 9 mucking machines, 31 atomized water coal slurries inlet, 32 air intakes.
The specific embodiment
Below in conjunction with description of drawings.
The utility model is horizontal cube structure, form by upper and lower two parts, there is the chimney arch 1 of " door " font body of heater inside, bottom, in the chimney arch is combustion chamber 2, also have on the chimney arch 1 flatly, be used to install water coal slurry burner 3, have two mouthfuls on the water coal slurry burner 3, be respectively atomized water coal slurry inlet 31 and air intake 32; Top is body of heater radiant section 4, body of heater radiant section 4 outsides have two mouthfuls, one is conduction oil inlet 5, another is conduction oil outlet 7, connect with coil pipe 6 between two mouthfuls, body of heater radiant section 4 connects ash dropping hopper 8 near the below of conduction oil outlet 7, and there is mucking machine 9 ash dropping hopper 8 belows, and the ashes that burning produces can be discharged from mucking machine 9.
The course of work of the present utility model is such: feed combustion chamber 2 through water-coal-slurry and air after the atomizing respectively by two connectors on the water coal slurry burner 3,2 mix the back ignition in the combustion chamber, but the coil pipe 6 in heat that burning produces and the flue gas heating furnace body radiant section 4, conduction oil in the coil pipe 6 is flowed out by conduction oil outlet 7 after absorbing heat, release heat with hot equipment heat exchange the time, the conduction oil after the release heat can flow into body of heater radiant sections 4 by the conduction oil inlet 6 of body of heater radiant section 4 and reheat.The water-coal-slurry of 2 burnings contains a spot of ashes in the flue gas of generation in the combustion chamber, assembles the back in the ash dropping hopper 8 that can connect and discharged by mucking machine 9 below body of heater radiant section 4.
