Description

A kind of vertical counter-burning three-pass boiler

Technical field

The utility model relates to boiler, the vertical counter-burning three-pass boiler that particularly a kind of thermal efficiency is high.

Background technology

In the prior art, existing its ignition condition of forward combustion boiler is that well air is fed in the stove by fire grate from bottom to top from furnace bottom, and coal is thrown from top to bottom on fire grate, and coal already produces high-temperature flue gas and is heated by the coal seam that newly adds.Close fire door behind the coal, air has only by fire grate and coal seam and just can enter in the stove, because the air capacity of the required consumption of different times of coal combustion is different, lack of air behind the coal causes fuel gas and carbon imperfect combustion, the loss increase.The hydrocarbon of separating out in the coal carries out thermal decomposition generation carbon black under the condition of high temperature and anoxic simultaneously, because the carbon black grain is little in light weight, the time compole that stays in stove is short, does not just also have enough time to burn and discharges with flue gas, causes the phenomenon of chimney over-emitting black exhaust easily.

The reverse burning boiler is more satisfactory from the burning angle, and burning of coal is more complete, also meets the requirements from environmental protection, aspect such as energy-conservation.But existing on the market at present back firing boiler, its burning degree is still not ideal enough, and also more complicated of structure, thereby causes manufacturing cost higher.

The utility model content

The purpose of this utility model is, a kind of vertical counter-burning three-pass boiler reasonable in design is provided, and it is simple in structure, and is easy to manufacture, effectively reduce manufacturing cost,, make coal to burn fully by reasonable structural design, thermal efficiency height is saved resource, and safeguards easily.

As further improvement of the utility model, corresponding described horizontally-arranged string water pipe also is provided with two openable water supply tanks on the sidewall of courage outside described, and this two water supply tank is located at the two ends of this horizontally-arranged string water pipe respectively, and this water supply tank communicates with the cavity of lower furnace body.

As further improvement of the utility model, it also comprises a base, and this base is located at the below of lower furnace body, and this base hollow and communicate with inner bag is provided with a cleaning door that is used to clear up slag in this base.

As further improvement of the utility model, be provided with the fire hole of disclosing that fire door and that an inspection opening, of checking flame or cleaning inner bag wall black dirt is used for stoking is used to disclose fire on the described lower furnace body from top to bottom successively.

As further improvement of the utility model, the corresponding described smoke-box of going up is provided with an inspection opening respectively with following smoke-box place on the described upper furnace body.

The beneficial effects of the utility model are: the utility model is simple and reasonable, and is easy to manufacture, effectively reduces manufacturing cost, by reasonable structural design, makes coal to burn fully, and thermal efficiency height is saved resource, and safeguards easily.

Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.

Description of drawings

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

The specific embodiment

Embodiment: see Fig. 1, a kind of vertical counter-burning three-pass boiler of the utility model, it comprises a upper furnace body 1 and a lower furnace body 2, this upper furnace body 1 is located at this lower furnace body 2 tops, described lower furnace body 2 comprises that an inner bag 21 and that serves as the combustion chamber serves as the outer courage 22 of shell, be the cavity 23 of a belly shirt water between this inner bag 21 and the outer courage 22, the top of this inner bag 21 is provided with some horizontally-arranged string water pipes 24; Described upper furnace body 1 is the cavity 11 of a belly shirt water, in this cavity 11, be provided with on the some vertical fire tubes 12, some anti-burnings chamber 13, one smoke-box 14 and smoke-box 15 once, the bottom of described vertical fire tube 12 is communicated with inner bag 21, the top of described vertical fire tube 12 is communicated with last smoke-box 14, should go up between smoke-box 14 and the play smoke-box 15 by anti-burning chamber 13 and be communicated with, this time smoke-box 15 connects a chimney 16, is communicated with by a tube connector 3 between the cavity 11 of this upper furnace body 1 and the cavity 23 of lower furnace body 2.
