Abstract
The utility model discloses a coal burning boiler with an N-shaped fire tube, which comprises a boiler body 1 in the structure of an existing fire-tube type boiler, a sealing cover 4, a chimney 12, an ash chamber 7 and a fire tube 2 and connecting seal heads 3 arranged on the upper end and the lower end part of the fire pipe 2. A moulded coal boiler also comprises a moulded coal burning chamber 5, a coal-pushing device 9 and a moulded coal fuel gas guiding arch 11. A pulverized coal boiler comprises a pulverized coal burning chamber 6, a dust guard 8 inside the boiler and an energy-saving stove 10. The coal burning boiler with the N-shaped fire tube is characterized in that the fire tube 2 is the N-shaped fire tube composed of three stages or more than three stages of tubes. The utility model increases the use of the burning heat energy through improving the structure of the fire tube. The utility model not only has the advantages of small boiler body, less material consumption, and easy manufacture and maintenance, but also has the calorific efficiency which is higher than a water tube boiler, solves the problem of larger volume of the small coal burning boiler and can be used as the small coal burning boiler.
Description
Technical field
The utility model relates to a kind of coal-burning boiler, particularly a kind of structure of fire-tube type coal-burning boiler.
Background technology
At present, the small scall coal-fired boiler major part all adopts the water-tube boiler structure, and the advantage of water-tube boiler is that the thermal efficiency is higher than multitubular boiler, and shortcoming is that body of heater is relatively large, and consumptive material is many, complex manufacturing technology, not easy care.
Summary of the invention
The purpose of this utility model is, a kind of coal-burning boiler of N shape fire tube is provided.This boiler not only body of heater is little, and consumptive material is few, be easy to make and safeguard, and the thermal efficiency is higher than water-tube boiler.
The utility model is to realize like this.The coal-burning boiler of N shape fire tube constitutes body of heater 1, capping 4, chimney 12, cinder chamber 7, the fire tube 2 comprise in the existing fire-tube type boiler structure, and what be provided with in the upper end of fire tube 2 and bottom is connected end socket 3; For molded coal boiler also comprise moulded coal combustion chamber 5, push away device for coal 9, moulded coal combustion gas guiding arch 11; Then comprise dust board 8 in pulverized coal combustor 6, the stove, whirlwind powder machine 10 for pulverized-coal fired boiler.No matter be molded coal boiler or pulverized-coal fired boiler, the characteristics of N shape fire tube coal-burning boiler are: described fire tube 2 is the N shape fire tubes that are made of the pipe more than three sections or three sections.
In the coal-burning boiler of above-mentioned N shape fire tube, described connection end socket 3 is preferably arc and connects end socket.
Compared with the prior art, the utility model has increased the utilization to combustion heat energy by improving the structure of fire tube.Accomplished that not only body of heater is little, consumptive material is few, be easy to make and safeguard, and the thermal efficiency is higher than water-tube boiler.Solved the bigger problem of small scall coal-fired boiler volume.The utlity model has simple in structurely, cost of manufacture is low, and effect is characteristics preferably.Can be used as small scall coal-fired boiler uses.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations of the N shape fire tube coal-burning boiler of coal dust type;
Accompanying drawing 3 is structural representations of horizontal N shape fire tube coal-burning boiler.
The specific embodiment
Embodiment.As shown in Figure 1, moulded coal (as the square briquette) coal-burning boiler of N shape fire tube, constitute the body of heater 1, capping 4, chimney 12, cinder chamber 7, the fire tube 2 that comprise in the existing fire-tube type boiler structure, what be provided with in the upper end of fire tube 2 and bottom is connected end socket 3, connect end socket 3 and be preferably arc connection end socket, constitute water storehouse between the last low head; Also comprise moulded coal combustion chamber 5, push away device for coal 9, moulded coal combustion gas guiding arch 11; Then comprise dust board 8 in pulverized coal combustor 6, the stove, whirlwind powder machine 10 (referring to accompanying drawing 2) for pulverized-coal fired boiler.No matter be molded coal boiler or pulverized-coal fired boiler, the characteristics of N shape fire tube coal-burning boiler are, described fire tube 2 is the N shape fire tubes that are made of the pipe more than three sections or three sections, is about to three (or five) a group of 1 original font fire tube and carries out end to end formation N shape fire tube.Practical result proves, adopts the coal-burning boiler of N shape fire tube, owing to prolonged the stroke of high-temperature fuel gas in stove, has not only increased the utilization to combustion heat energy, and the thermal efficiency is higher than water-tube boiler, and body of heater is little, and consumptive material is few, is easy to make and safeguard.The utility model also can be applicable in the horizontal coal-fired boiler shown in the accompanying drawing 3.
Claims (2)
1, the coal-burning boiler of N shape fire tube, constitute and comprise body of heater (1), capping (4), chimney (12), cinder chamber (7), fire tube (2), what be provided with in the upper end of fire tube (2) and bottom is connected end socket (3), and moulded coal combustion chamber (5), push away dust board (8), whirlwind powder machine (10) in device for coal (9), moulded coal combustion gas guiding arch (11) or pulverized coal combustor (6), the stove; It is characterized in that: described fire tube (2) is the N shape fire tube that is made of the pipe more than three sections or three sections.
2, the coal-burning boiler of N shape fire tube according to claim 1 is characterized in that: described connection end socket (3) connects end socket for arc.
