Abstract

The invention provides a novel gas boiler which comprises a boiler shell, a combustion chamber, a boiler inner cavity, a boiler door, a built-in smoke box and a smoke pipe set communicated with the smoke box. The boiler inner cavity is provided with an upper cavity body and a lower cavity body; the smoke pipe set is positioned inside the upper cavity body; the combustion chamber is positioned inside the lower cavity body; a water jacket is arranged on the outer wall of the combustion chamber; a plurality of groups of inner water pipes are arranged at the positions, which are close to the inner wall, inside the combustion chamber in a run-through manner and continuous waterways are formed by the inner water pipes and a water jacket inner cavity through water separators; an upper water outlet of the upper cavity body is communicated with a lower water inlet of the lower cavity body; a lower water outlet is communicated with the water jacket; the other end of the water jacket is provided with a pipeline for being communicated with the outside; water flow enters the water jacket to be heated after being preheated through the upper cavity body and the lower cavity body which are communicated mutually. The novel gas boiler has the advantages that forced circulation is adopted to enable water to be always in a flowing state after entering the boiler; heat of smoke pipes is effectively utilized to carry out preheating; the heating area is increased by the inner water pipes inside the combustion chamber; repeated utilization of heat is implemented; heating time is reduced; the novel gas boiler is energy-saving and environmental-friendly.

Description

A kind of gas-fired boiler
Technical field
The present invention relates to boiler technology, be specifically related to a kind of gas-fired boiler.
Background technology
Along with becoming increasingly conspicuous of environmental problem, the improvement of country for traditional energy and the development to new forms of energy are paid attention to gradually, natural gas is more and more extensive as a kind of eco-friendly power source application, also many gas fired-boilers are had on the market, although take into account the waste heat utilizing flue gas when some boiler design, but its mode of heating still rests on and cold water to be heated is filled into boiler internal, again water is released after cold water being heated to assigned temperature.In addition the combustion chamber of most of gas fired-boiler is light wall construction, the heat that can not effectively utilize fuel gas buring to produce, and the heat time increases, inefficiency and result in the waste of the energy.
Summary of the invention
The present invention is directed to above deficiency and a kind of mode of heating adopting omnidistance flowing is provided, effectively utilize fume afterheat, increase the heating surface (area) (HS of combustion chamber and water simultaneously, improve the gas-fired boiler of the efficiency of heating surface.
The present invention is by the following technical solutions: a kind of gas-fired boiler, the smoke pipe group comprising boiler shell, combustion chamber, boiler intracavity, fire door, built-in smoke box and be communicated with smoke box, described boiler intracavity is provided with upper cavity and lower chamber, smoke pipe group is positioned at upper cavity inside, described combustion chamber is positioned at lower chamber inside, and described outer wall of combustion chamber is provided with water jacket;
Described upper cavity is respectively equipped with water inlet and upper water-out mouth, and lower chamber is provided with lower water inlet and lower outlet;
Upper water-out mouth is communicated with lower water inlet, and lower outlet is communicated with water jacket, and the other end of water jacket is provided with pipeline and is in communication with the outside, and current, after the upper cavity that is interconnected and lower chamber preheating, enter heating in water jacket.
Preferably, described combustion chamber is provided with many groups and runs through inwall and the inner conduit of inner space with described water jacket near the place of inwall, increase heating surface area, improve heat transfer efficiency in water flows in water jacket.
Preferably, the inner chamber of described water jacket is provided with several and is separated at two ends of described inner conduit and be communicated with into the dividing plate of water channel, and water flows in water channel increases the time of contact of water and heating surface further.
Preferably, upper water inlet and lower water inlet lay respectively at below the side of upper cavity and lower chamber, upper water-out mouth and delivery port are separately positioned on the top of opposite flank, water jacket connects described lower outlet and is positioned at below, top is positioned at extraneous junction, cold water enters from bottom and flows out from top, meets convective principles.
Preferably, described upper cavity and described lower chamber, for removably connecting, conveniently carry out processing combination.
Usefulness of the present invention is, change tradition by the mode of whole for water stove heating, adopt forced circulation to make water after the inside entering boiler, be in the state of flowing, effectively utilize the heat of smoke pipe to carry out preheating, the inner conduit of combustion chamber increases heating surface (area) (HS always, the water channel laser heating that water is formed at water jacket and inner conduit, can realize continuing to supply water, realize heat and repeatedly utilize, reduce the heat time, energy-conserving and environment-protective, economize energy.

1. upper cavities in figure, water inlet on 11., 12. upper water-out mouths, 13. smoke pipe group, 2. lower chambers, 21. times water inlets, 22. lower outlets, 3. smoke box, 4. water jacket, 5. dividing plate, 6. inner conduit, 7. combustion chamber.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Figure 1 shows that the structural representation of an embodiment of the present invention, the smoke pipe group 13 comprising boiler shell, combustion chamber 7, boiler intracavity, the fire door just right with burning, built-in smoke box 3 and be communicated with smoke box 3, boiler internal is provided with upper and lower two independently cavitys, the inner combuster 7 of lower chamber 2, smoke pipe group 13 is positioned at the inside of upper cavity 1, upper cavity 1 is respectively equipped with water inlet 11 and upper water-out mouth 12, and lower chamber 2 is provided with lower water inlet 21 and lower outlet 22; Combustion chamber 7 outer wall is provided with water jacket 4, and water jacket 4 one end is communicated with lower outlet 22, and the other end is in communication with the outside.Combustion chamber runs through the inner conduit 6 having and be communicated with water jacket 4 inner chamber near the position of inwall, the inner chamber of water jacket 4 also welds to be separated the two ends of inner conduit 6 and to form the dividing plate 5 of continuous water channel.
Upper water inlet 11 and lower water inlet 21 lay respectively at below the side of upper cavity 1 and lower chamber 2, and upper water-out mouth 12 and delivery port 22 are separately positioned on the top of opposite flank, and water jacket 4 connects described lower outlet 22 and is positioned at below, is positioned at top with extraneous junction.
Figure 2 shows that water circulation circuit of the present invention, the heat cycles of water is path is such: upper water inlet 11 mouthfuls is communicated with extraneous water inlet equipment, in upper cavity 1 smoke pipe group 13 preheating after by upper water-out mouth 12 discharge enter lower water inlet 21, secondary preheating is carried out by lower combustion chamber 7, the water of secondary preheating flow out from the lower outlet 22 on lower chamber 2 top enter water jacket 4 chamber in heat, water water jacket 4 inner chamber through inner conduit 6 directly contact gas flame carry out heating flow a to upper lateral part of water jacket 4 and flow out to extraneous water supply.
The effect that the present invention saves combustion gas is very remarkable, as being that 18 DEG C of water are heated to 42 DEG C by 1 ton of initial temperature, general gas boiler need use combustion gas 4 ~ 5 cubic metres, the present invention is utilized then only to need the combustion gas of about 2 cubic metres, save combustion gas 50%, effect is fairly obvious, and the heat time shortens, can continue to supply water, realize energy-conserving and environment-protective.
