The invention discloses a whole wet back horizontal type normal pressure fuel oil hot-water boiler with flame returning in a center. The whole wet back horizontal type normal pressure fuel oil hot-water boiler mainly comprises a boiler barrel, a boiler furnace, a front smoke box, a water back, a back smoke box, a smoke pipe, a chimney port and a burner. The special boiler furnace serves as a main heat exchanging component, the main method of heat exchanging of the boiler furnace is radiation, the water back and the front smoke box are radiation heating surfaces, and the heat efficiency of the boiler is high. The boiler furnace, the front smoke box, the water back and the back smoke box are surrounded by working medium water, the radiation and convection heating surface is enlarged, the high-temperature parts of all walls of the boiler can be reliably cooled, and the boiler can operate safely. A water inlet is formed in the low-temperature area between the boiler furnace and the back smoke box, and therefore the structure of a boiler body is simplified. The front smoke box and the back smoke box are provided with a check hole and a maintaining hole respectively, and the chimney port can serve as a front maintaining hole, so that manufacturing and maintaining are convenient. The testing result shows that the heat efficiency of the boiler is more than 95% when the exhaust smoke temperature is controlled about 100 DEG C.
Description
Technical field
The present invention relates to oil burning boiler technical field, particularly flame wet back of the body Horizontal normal pressure oil-fired water-boiler is entirely returned at a kind of center.
Background technology
Progress along with technology, existing horizontal atmospheric fuel hot-water boiler has been done a large amount of improvements in combustion chamber and smoke box structure, generally a combustion chamber and two smoke boxes, consists of, and smoke box outside in front and back is the dry back of the body, improved to a certain extent the thermal efficiency, the thermal efficiency can reach 83% left and right.For further improving the thermal efficiency of boiler, reducing pollutant emission is of value to environmental protection, avoids drawback, and the combustion chamber of existing horizontal atmospheric fuel hot-water boiler and the setting of smoke box and structure need further improvement.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of center and return flame wet back of the body Horizontal normal pressure oil-fired water-boiler entirely, it is simple in structure, and the thermal efficiency is high, and pollutant emission is lowerd, easy to operate.
For achieving the above object, the present invention adopts following technical scheme:
A flame wet back of the body Horizontal normal pressure oil-fired water-boiler is entirely returned at center, comprises drum, flue, front smoke box, the water back of the body, rear smoke box, dress watch mouth, smoke pipe, throat and burner.Wherein, flue is the cylinder of left end spheroid shape end socket, be arranged on the centrosymmetric middle and lower part of boiler body near burner one side, the both sides, front and back of flue are respectively equipped with front smoke box, the water back of the body and rear smoke box, the open communication front smoke box of flue, the water back of the body, is provided with threaded flue in the surrounding of flue, and threaded flue is communicated with front smoke box, the water back of the body and rear smoke box, the top of front smoke box, the water back of the body is provided with throat, smoke box and throat after being communicated with by smooth smoke pipe.Working-medium water space is formed by the insulating space of drum and flue, front smoke box, the water back of the body, rear smoke box, smoke pipe, in the bottom of drum, is provided with sewage draining exit and water inlet, and the top of drum is provided with delivery port, atmosphere entry and temperature-measuring port.Right side at front smoke box is provided with inspection socket, and install combustion device, with refractory cement and asbestos board sealing, burner directly sprays into flue by the central authorities of inspection socket by flame, the left side of rear smoke box is provided with service port, with the sealing of asbestos board and refractory cement, at the skin of drum, is provided with heat-insulation layer.
During work, running water pipe connection or circulating backwater are entered to water inlet, water filling or circulating backwater are in drum.By program controller, open burner, flame sprays to flue from burner, and the rear inside wall that arrives flue is turned back, and flame completes a backhaul; Return flame is along the periphery courage wall of flue to front smoke box and the water back of the body, through threaded flue to after smoke box, complete second backhaul; Flame is discharged to throat through smooth smoke pipe from the top of rear smoke box again, completes the 3rd backhaul.Flame institute through flue, front smoke box, the water back of the body, threaded flue, after the surrounding of smoke box and smooth smoke pipe all fill working-medium water, each wall of combustion high temperature sweep of gases of fuel oil is passed to the working-medium water in drum by heat energy, make the working-medium water of drum reach the required temperature of heat supply, from delivery port by water pump extract out, after heat exchange, working-medium water flows back to water inlet and realizes working-medium water and circulate, go round and begin again.
The using method of other parts is identical with the boiler of prior art.
If the present invention is Special alcohol group fuel burner by burner coupling, flame wet back of the body Horizontal normal pressure alcohol radical oil-fired water-boiler is entirely returned at the center of transforming as, can coal, burnt byproduct is fuel, and its cost performance is higher.This technical scheme also belongs to protection scope of the present invention.
Beneficial effect of the present invention
First, structure of boiler body of the present invention is different from regular fuel boiler, with special flue as main heat exchange component, and the heat exchange of flue be take radiation as main, convection current composition is less, because the biquadratic of Fire Radiation heat exchange and temperature is directly proportional, therefore, the thermal efficiency of boiler of the present invention is higher.
Secondly, flue, the water back of the body and water-cooled revolution front smoke box are as radiation heating-surface, except burner interface section and service port part, after water-cooled revolution front smoke box, the water back of the body and water-cooled revolution, smoke box is all surrounded by working-medium water, so not only increased radiation, convection heating surface but guarantee before and after boiler smoke box everywhere the high temperature atmosphere of wall all obtain coolingly reliably, guarantee safe operation of the boiler.
The 3rd, boiler is two backhaul smoke pipes, can obtain abundant heat convection, and the cross section ratio of two backhaul smoke pipes appropriate (being greater than 1), and the first backhaul is threaded flue, and the second backhaul is smooth smoke pipe, guarantees that flue gas flow rate is stable.
The 4th, water inlet is arranged on to the low-temperature space in the middle of flue and rear smoke box, save stove internal partition, simplify structure of boiler body.
The 5th, boiler of the present invention is respectively equipped with inspection socket and service port at forward and backward smoke box, and chimney interface also can be used as front service port, and this structure is convenient to manufacture and safeguard.The condensed water occurring in chimney can be derived by chimney bottom, can not enter in boiler.
Boiler of the present invention in actual motion after tested result show, exhaust gas temperature is controlled at 100 ℃ of left and right, the thermal efficiency of boiler reaches more than 95%, fuel saving successful, pollutant emission reduces.
