Automatic Loose Coal Feed Ventilation Combustion Supporter for Anti-firing Boiler

Abstract

The invention relates to an automatic coal loosening, feeding and ventilation combustion supporter, for a counter-heating boiler. The automatic coal loosening, feeding and ventilation combustion supporter comprises a plurality of middle combustion supporters (1) and two side combustion supporters (2). The middle combustion supporters (1) are hollow bodies, wherein the top parts of the hollow bodies are roof-ridge-shaped, the lower parts of the top parts of the hollow bodies are inverted-roof-ridge-shaped and the two side surfaces of the hollow bodies are open and communicated. A plurality of air vents (13) are respectively arranged on the two inclined walls of a coal loosening slope (12) of each middle combustion supporter (2). Each side combustion supporter is of the shape of half of the middle combustion supporter (1). The counter-heating boiler which uses the automatic coal loosening, feeding and ventilation combustion supporter has the advantages that the crushed coal with a coal surface can be used as fuel, the fuel can be ensured to be fully combusted, the energy is not wasted, the thermal efficiency of the boiler is high, the use cost is lower, the boiler is convenient to operate and use and the fuel coal is not limited; the problem that thick coal with the coal surface cannot be added into the combustion chamber of the counter-heating boiler in one step is solved, the effect of long-term combustion can be realized after the coal is added in one step, the coal adding frequency is greatly reduced, the boiler is not required to be looked after, the labor is saved and the thermal efficiency of the boiler is improved.

Description

technical field [0001] The invention relates to heating equipment, in particular to a reverse firing boiler. Background technique [0002] Traditional anti-firing coal-fired boilers are mainly suitable for lump coal as fuel. If crushed coal with coal surface is used as fuel, the coal seam in the coal storage box above the furnace cannot be added at one time, and can only be added less frequently. Otherwise, the coal seam containing the coal surface will swell due to the mutual extrusion of the coal surface during the falling process, so that the coal seam cannot fall naturally, and at the same time it will block the gaps between the lump coals, causing the combustion layer below the coal seam to be ventilated from top to bottom Bad, the lack of oxygen will make the coal combustion insufficient or unable to burn, which is a waste of energy, the temperature of the combustion chamber is low, and the thermal efficiency of the boiler will be greatly reduced, failing to achieve th...

Problems solved by technology

Otherwise, the coal seam containing the coal surface will swell due to the mutual extrusion of the coal surface during the falling process, so that the coal seam cannot fall naturally, and at the same time it will block the gaps between the lump coals, causing the combustion layer below the coal seam to be ventilated from top to bottom Bad, the lack of oxygen will make the coal combustion insufficient or unable to burn, which is a waste of energy, the temperature of the combustion chamber is low, and the thermal efficiency of the boiler will be greatly reduced, failing to achieve the purpose of energy saving and environmental protection

It can be seen that the current reverse combustion boilers are only suitable for using lump coal with high cost as fuel, the cost of fuel use is high, and the use of fuel is relatively limited

A large amount of energy is wasted every year and causes environmental pollution
