Description
Technical field
The utility model relates to a kind of condensing boiler, particularly relates to a kind of fuel oil, gas condensing multitubular boiler.Belong to Thermal Equipment technical field.
Background technology
Along with the reinforcement day by day of energy-conserving and environment-protective consciousness, the economic environmental protection of boiler runs and more and more receives publicity, and the utilization ratio improving the energy not only can reduce operating cost, can also environmental protect situation.Therefore, improve the efficiency of boiler, reduce the cost of boiler, make it reach maximum to the economic benefit of society and changed into question of common concern.
In every loss of boiler, ratio shared by flue gas loss is maximum, so first the efficiency improving boiler can start with from the heat made full use of flue gas, traditional Horizontal natural gas condensing boiler generally adopts the fin tube type economizer and condenser of using sheet metal coiling, and its finned tube is top seal formula structure.The use of this kind of finned tube makes the efficiency of boiler have more raising, but uses this kind of finned tube that the disturbance in exhaust gases passes can be made abundant not, and heat transfer effect still has much room for improvement, and this can be measured by actual motion.Under standard state, flue gas dew point, at about 60 DEG C, starts to occur condensed water to less than about 70 DEG C during our actual motion, goes out the uneven of temperature affect heat transfer effect from observable here, and the flue-gas temperature near finned tube is lower, and the temperature away from finned tube is higher.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of high-efficiency condensation fuel oil, gas multitubular boiler, the heat making it make full use of water vapour in boiler smoke to contain, and is converted into a part for the heat that boiler utilizes, improves boiler efficiency.
The purpose of this utility model is achieved in that a kind of jag formula finned tube condensation fuel oil, gas multitubular boiler, comprise drum, burner hearth, return combustion chamber, smoke pipe, front smoke box, economizer and condenser, described drum is horizontal layout, burner hearth, return combustion chamber and smoke pipe are all arranged in drum, burner hearth is placed in bottom in drum, return combustion chamber is arranged on rear side of burner hearth, and be connected with burner hearth cavity, smoke pipe is placed in drum internal upper part, front smoke box is arranged at drum front upper side, the tube side two ends of smoke pipe are connected with return combustion chamber with front smoke box respectively, economizer and condenser series connection are placed in the top outer of drum, economizer is connected with front smoke box, it is characterized in that: the finned tube of described economizer and condenser, its fin top is along the circumferential direction evenly provided with some slit ports to root.
The utility model jag formula finned tube high-efficiency condensation combustion gas multitubular boiler, the V-shaped structure of described slit port.
The utility model jag formula finned tube high-efficiency condensation combustion gas multitubular boiler, described economizer and condenser adopt adverse current to be staggered in arrangement.
The utility model jag formula finned tube high-efficiency condensation combustion gas multitubular boiler, described condenser adopts acid corrosion-resistant ND steel.
The beneficial effects of the utility model are:
Due to the reason of fuel in the flue gas of the condensing boiler of fuel oil, gas, often containing more water vapour, the flue gas that fuel oil, gas boiler are discharged is made full use of, when flue gas is by jag formula finned tube economizer condenser, by the strong disturbance effect of jag formula finned tube, make the water vapour in more flue gas have an opportunity to contact with finned tube, thus make water recovery wherein out.The jag formula finned tube condensation efficient boiler that the utility model relates to is simple for structure compact, successful, after jag formula finned tube economizer condenser, condensation water quantity showed increased, absorbed after making more steam gasification latent heat treatment, reduced exhaust gas temperature, improved boiler efficiency.

Detailed description of the invention
See the vertical section structure schematic diagram that Fig. 1, Fig. 1 are the utility model jag formula finned tube high-efficiency condensation combustion gas multitubular boiler.As seen from Figure 1, the utility model jag formula finned tube high-efficiency condensation combustion gas multitubular boiler, forms primarily of drum 7, burner hearth 1, return combustion chamber 2, smoke pipe 3, front smoke box 4, economizer 5 and condenser 6.Described drum 7 is in horizontal layout, burner hearth 1, return combustion chamber 2 and smoke pipe 3 are all arranged in drum 7, burner hearth 1 is placed in bottom in drum 7, return combustion chamber 2 is arranged on rear side of burner hearth 1, and with burner hearth 1 intracavity inter-connection, smoke pipe 3 is placed in drum 7 internal upper part, and front smoke box 4 is arranged at drum 7 front upper side, the tube side two ends of smoke pipe 3 are connected with return combustion chamber 2 with front smoke box 4 respectively, and economizer 5 and condenser 6 series connection are placed in the top outer of drum 7.Economizer 5 is connected with front smoke box 4.Economizer 5 and condenser 6 adopt adverse current to be staggered in arrangement, and condenser adopts acid corrosion-resistant ND steel.
See Fig. 2 ~ 3, Fig. 2 is the finned tube end view drawing that the utility model relates to.Fig. 3 is the finned tube Facad structure schematic diagram that the utility model relates to.As can be seen from Fig. 2 and Fig. 3, the finned tube of economizer 5 and condenser 6, its fin top is along the circumferential direction evenly provided with some slit ports 61 to root, the V-shaped structure of slit port 61, strengthens heat transfer effect to strengthen flue gas disturbance.
Flue gas from burner hearth out, enter 180 DEG C of turnings after return combustion chamber, to smoke pipe, more upwards proceed to the economizer being placed on boiler top through front smoke box, finally enter condenser thereafter, in economizer, condenser, flue gas containing more water vapour and jag formula finned tube flue gas are subject to comparatively strong disturbance, and pipe inner cold water and flue gas heat exchange coefficient increase, and the flue gas of heat runs into cold fin and tube wall, make the water recovery in boiler smoke, and produce the more condensed water of the finned tube comparing not jag.Simultaneously fume gas condensation is released the more latent heat of vaporization and is taken away by cold water, and water temperature rises.Reach flue-gas temperature to reduce further, the object that boiler efficiency raises further.
