Abstract

The utility model discloses an energy-saving coal burning boiler, which comprises a boiler body, a water heat exchanging pipe, a combustion chamber, and a smoke cabin and a smoke discharging pipe, which are arranged above the combustion chamber, and an upper fire grate and a lower fire grate, which are arranged below the combustion chamber, and an upper boiler door and a lower boiler door, which are arranged on the boiler body and correspond to the upper and the lower fire grates, and an ash removal chamber and an ash removal door, wherein the upper boiler door is provided with a ventilation port. The energy-saving coal burning boiler not only can ensure the adequate combustion, but also can prevent the energy waste caused by directly opening the upper boiler door and always burning the new coal; moreover, during the application process, the upper boiler door is free from being controlled to be opened and closed through the manual frequent examination of the temperature, so the labor is saved for the coal which is added at one time can be burned for three to four hours, while the energy is saved; by adopting the above structure, 30 percent of coal can be saved compared with the normally-opening of the boiler door, so the application cost is effectively reduced, and the energy-saving coal burning boiler is more environment-friendly; and the coal slag, or the coal ash and the like can be easily overlaid on the coal above the lower fire grate, so the temperature can be conveniently and efficiently controlled, and the energy can be efficiently saved.

Description

The energy-saving coal boiler

Technical field

The utility model relates to a kind of boiler, relates in particular to a kind of energy-saving coal boiler.

Background technology

In recent years, the boiler that with coal-fired (comprising coal cinder, coal briquette, coke etc.) be fuel uses extensive in industry and civil area, their ubiquitous problems are that fired coal combustion is incomplete, and over-emitting black exhaust wastes energy and contaminated environment, if burn and fire door opened, though overcome this defective of incomplete combustion, take very much coal, in the use of reality, need the user to open or close fire door often according to temperature requirement, the energy and cost of labor are all higher.

The utility model content

In view of this, technical problem to be solved in the utility model is: a kind of energy-saving coal boiler that can effectively reduce use cost is provided.

In order to achieve the above object, the utility model adopts following technical scheme to realize:

A kind of energy-saving coal boiler, comprise body of heater, hydrothermal exchange pipe, combustion chamber, be located at combustion chamber top tabacco barn and smoke exhaust pipe, be located at the below, combustion chamber upper fire-grating, lower fire grating, be located on the body of heater and upper furnace door corresponding and lower furnace door with upper and lower fire grate, and dedusting chamber and ash door, wherein, offer ventilating opening on the described upper furnace door.

As preferably, described ventilating opening is the ventilating opening that valve constitutes.

As preferably, described lower fire grating is provided with a device that is used for the splendid attire material near the position of lower furnace door, and described body of heater is provided with and the material in this device can be fallen in the control device of described lower fire grating top.

As shown from the above technical solution, the beneficial effects of the utility model are:

Compared to existing technology, energy-saving coal boiler of the present utility model is by offering ventilating opening on the upper furnace door, can not only make full combustion of fuel, can also avoid directly opening wide the energy waste that upper furnace door brings, and in use no longer need artificial running audit temperature to come the gauge tap upper furnace door, in the time of energy savings, also saved artificial, adding a dant can manage three to four hours, after adopting such structure, can burn than normal unlatching fire door and save 20 percent coal, thereby effectively reduced use cost, and, owing to adopt the coal ash that blocks that the valve ventilating opening can also be suitable, therefore more environmental protection, and be provided with a device that is used for the splendid attire material near the position of lower furnace door at lower fire grating, described body of heater is provided with and the material in this device can be fallen in the control device of described lower fire grating top, the user can cover cinder or coal ash etc. on the coal of lower fire grating top easily, thereby control temperature easily and effectively, and effective energy savings, can be than normally only burning Xin Mei economizes 10 coal, therefore, the utility model passes through last, the design of lower furnace door can be saved coal consumption 30 percent than the boiler of prior art.

Fig. 1 is a perspective view of the present utility model.

The specific embodiment

In order to make those skilled in the art can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing.

See also shown in Figure 1, the utility model provides a kind of energy-saving coal boiler, comprise body of heater 1, hydrothermal exchange pipe (not shown), combustion chamber (not shown), be located at combustion chamber top tabacco barn 2 and smoke exhaust pipe 3, be located at the below, combustion chamber upper fire-grating (not shown), lower fire grating (not shown), be located on the body of heater 1 and upper furnace door 4 and the lower furnace door 5 corresponding with upper and lower fire grate, and dedusting chamber's (not shown) and ash door 6, wherein, offer ventilating opening 7 on the described upper furnace door.The ventilating opening that described ventilating opening 7 constitutes for valve.Described lower fire grating is provided with a device (not shown) that is used for the splendid attire material near the position of lower furnace door 5, and described body of heater is provided with and the material in this device can be fallen in the control device (not shown) of described lower fire grating top.Described control device can adopt the lever principle structure, also can adopt electronic-controlled installation, the technology of this control device is a known technology, in the utility model, it is used for coal ash or the quick new coal above lower fire grating of cinder that splendid attire material device is filled or has burnt the coal of combustion, both kept the suitable temperature in the stove, the consumption of having saved coal again, more convenient user's operation.

But the above only is a preferable possible embodiments of the present utility model, is not in order to limit to claim of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, all in like manner to be included in the scope of the present utility model.
