Description

Full-premixing condensing low-nitrogen cast silicon-aluminum gas boiler

Technical Field

The utility model relates to a gas boiler technical improvement field specifically is low nitrogen of full premix condensation casts silicon-aluminium gas boiler.

Background

The gas boiler converts chemical energy into heat energy in the combustion chamber, so that the inner wall of the combustion chamber is heated, and water outside the combustion chamber is evaporated to condense and exchange heat. The length of the combustion chamber of the existing gas boiler is longer than the spraying length of flame, so in order to ensure that the combustion chamber has no local high temperature and relatively uniform heating requirements, the existing method is carried out by increasing the flow speed and flow of gas. The disadvantages of this approach are significant. First, it is clear that this approach is wasteful of gas, increasing enterprise costs; secondly, as is well known, the outer flame temperature of the flame is high, the inner flame temperature is lower than that of the outer flame, the flame jet diameter close to the burner nozzle is increased after the gas flow rate and the gas flow are increased, the inner flame and the outer flame cannot be utilized in a region which is a quarter of the length of the combustion chamber away from the burner nozzle, and most of the inner flame is heated. Therefore, there is no reasonable place to increase the flow rate of the gas, so we want to provide an improvement of the internal structure of the gas boiler to structure the problem.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

Full premix condensation low nitrogen casts aluminosilica gas boiler, major structure includes the furnace body, 1 both sides of combustion chamber of furnace body set up combustor 2 respectively and converge smoke chamber 3, set up in the combustion chamber 1 and lead flame ware 4, lead flame ware 4 and be the toper, lead the awl point of flame ware 4 and aim at combustor 2, the one end that the awl point was kept away from to lead flame ware 4 is equipped with 1 interior circle diameter matched with cooperation foot spare 5 of combustion chamber, cooperation foot spare 5 is equipped with 2 at least, cooperation foot spare 5 outer end cooperatees with 1 inner wall cambered surface of combustion chamber, and the dismouting is carried out to convenient flame ware 4 of leading, and its cooperation mode is clearance fit. When the flame guider 4 is disassembled, the end cover 10 at the observation port is firstly disassembled, and the disassembly and the assembly are carried out from the smoke converging cavity 3. The front end cover 10 is removed for cleaning the inside of the combustion chamber 1.

The distance between the conical tip of the flame guide 4 and the nozzle of the burner 2 is one fourth of the length of the combustion chamber 1. Experiments show that the distance of about one fourth is the most reasonable, and the best flame guide effect can be achieved.

The annular array of the matching foot parts 5 is provided with 3. The 3 engagement legs 5 are able to engage well with the inner wall of the combustion chamber 1 in order to support the eccentric flame guide 4.

The flame guider 4 is of a hollow cone barrel structure, the hollow cone barrel structure is used for reducing the weight of the flame guider 4, and the outer wall of the flame guider 4 is provided with smoke outlet air holes 6. The smoke outlet vent 6 is used for better discharging smoke to the smoke collecting cavity 3, and certainly, the smoke can also be discharged through the smoke discharge gap 11 between the adjacent matched foot pieces 5.

The cooperation foot spare 5 includes connecting plate 7 and cambered plate 8, cambered plate 8 cooperatees with 1 inner wall cambered surface of combustion chamber, be connected through connecting plate 7 between cambered plate 8 and the flame guide 4. The connecting plate 7 is provided with a through hole 9. The through hole 9 is arranged to facilitate the detachment of the flame guide 4 from the combustion chamber 1 by pulling out the flame guide, and the through hole 9 is hooked by a hook and pulled outwards, so that the flame guide can be conveniently pulled out.

The process of completing this design:

in the former time, a flame tube with holes is arranged to compress the flame at the near end to achieve the purpose by adopting the mode shown in the attached figure 5 of the specification, but the mode has too large heat loss to the flame, a large amount of flame is lost on the tube wall, and the heating efficiency is reduced. Therefore, I finally choose the scheme shown in the attached figure 1 of the specification.

I explain the scheme of the attached figure 1 of the specification:

as shown in the attached figure 1 of the specification, by arranging the flame guide 4 in the combustion chamber 1, the distance between the conical tip of the flame guide 4 and the nozzle of the combustion chamber 2 is one fourth of the length of the combustion chamber 1, the sprayed flame can be guided along the conical surface at the conical tip of the flame guide 4, so that the flame is generally in a column shape shown in the attached figure 1 of the specification, but not in a drop shape shown in the attached figure 4 of the specification, the attached figure 4 of the specification is a flame state when the flame guide 4 is not used under the same gas flow rate state, the flame state shown in the attached figure 4 of the specification can prevent one end of the combustion chamber 1 on one side of the principle combustion chamber 2 from being effectively heated, and the phenomena of local high temperature and uneven heating can occur in the combustion chamber 1. The technique shown in figure 1 of the accompanying drawings is well suited to heating the combustion chamber 1 by means of the outer flame of a flame. The advantages of using the flame guide 4 can be clearly derived by comparing the description with the attached figure 1 and the attached figure 4. The flame emitted is thus guided by the flame guide 4, so that the requirement of relatively uniform heating without locally high temperatures in the combustion chamber 1 is substantially optimally solved.
