Secondary combustion device of boiler exhaust

Figure 1 is the overall morale of the present invention.

2 is a cross-sectional view taken along line A-A of the present invention.

3 is a state of use of the present invention.

4 is a state of use of another embodiment of the present invention.

5 is an elevation view of the present invention viewed from the stack side.

The present invention installs an exhaust gas secondary combustion device in the exhaust compartment that separates the combustion chamber of the boiler to re-burn the exhaust gas including the smoke that passes after being burned in the main combustion chamber to burn the exhaust gas as much as possible and pass through the stack. The final exhaust is related to the secondary combustion device of the boiler exhaust gas by contributing to the increase of thermal efficiency, energy saving and pollution prevention by reducing the content of soot.

In conventional boilers, the flame temperature drops while the flame is diffracted 2-3 steps along the passage formed by the diaphragm partitioning the main combustion chamber and each combustion chamber, so that the smoke contained in the flame does not burn in the exhaust section and passes as it is. Furnace is unburned, which not only contributes to pollution and obsolete accessories, but also leads to enormous reductions in thermal efficiency, energy loss and pollution due to the consumption of unburned fuel.

This is because the structure of the conventional boiler is a monotonous flame-passing method, and it is not possible to burn the soot contained in the exhausted gas by the atmospheric heat passing through the heat-transfer surface passage or the exhaust part after being continuously radiated in the water pipe or the associated pipe.

The present invention is to provide a secondary combustion chamber between the exhaust section and the stack of the combustion chamber in the boiler by vortexing the quartile and waste heat to form a secondary combustion chamber to reburn the soot passing through it.

Hereinafter, the subject matter of the present invention will be described in detail with reference to the accompanying drawings.

The inlet burner (1) and the burner burner (2), which are made of a ceramic material or a non-flammable synthetic resin material, are formed in one set, and the intake burner (1) has different inclination angles. &Quot; form combustion chambers 3 and 3 ', and the exhaust combustion ports 2 also have different inclination angles. &Quot; "The combustion chamber 4 and the discharge port 5 are formed, and the front end of the discharge port 5 is a structure in which the streamlined guillotine 6 was fixed as the support body 7 (7 '), such a suction combustor 1 and discharge | emission. By using the combustor 2 as a set, a suitable number of devices in the space between the heavy combustion chamber 9 and the exhaust section 10 of the boiler 8 are stacked vertically and horizontally.

In the figure, reference numeral 11 denotes a damper.

The present invention as described above, the exhaust gas passing through the suction combustion port (1) in the course of passing the exhaust gas burned in the main combustion chamber (9) of the boiler (8) along the stack is different inclination angle " "In the combustion chamber 3 ', the exhaust velocity is changed and stagnated so that it is re-burned by the atmosphere heat and then the exhaust gas which has advanced to the exhaust combustion port 2 is" By the second reburn in the combustion chamber 4 while being rotated, vortexed, or partially stagnated and blocked by the mold space and streamlined warhead 6, the exhaust passing through the damper 11 is a complete combustion.

In addition, depending on the size and structure of the boiler can be stacked in a multi-stage arrangement as shown in FIG.

Therefore, the present invention catches atmospheric heat that is thrown away by waste heat and uses it as a heat source for re-combustion, which improves thermal efficiency using waste heat and completely burns unburned soot, resulting in the effect of fuel saving and pollution prevention without emitting soot. It is effective to install and spread widely.
