Abstract

Disclosed is an environmentally-friendly and energy-saving civil coalball with adjustable furnace fire, which is pressed by pulverized coal and auxiliary materials after the even mixing according to certain proportion. A central hole with a big diameter is arranged in the center of the civil coalball in the utility model and a plurality of small-diameter burning holes are evenly distributed around the central hole. The central hole mainly delivers sufficient hot air, while the burning holes mainly generate large amount of carbon monoxide. The device has the advantages of environmental protection and energy saving compared with the current product and the furnace fire is adjustable.

Description

Civil coal ball

Technical Field

The utility model relates to a civil coal ball, in particular to an environmental protection and energy saving civil coal ball.

Background

At present, the known civil honeycomb briquette is formed by uniformly mixing and pressing pulverized coal and auxiliary materials, and the combustion holes of the honeycomb briquette are the same in size. When it is put into a coal stove to be ignited, in the initial stage of combustion, a large amount of carbon monoxide, which is extremely toxic to humans, is generated due to the high fuel concentration in the upper honeycomb briquette and is discharged into the air. Thus, firstly, air is severely polluted; secondly, energy is wasted; thirdly, the thermal efficiency is low. In the middle stage of combustion, the fuel concentration in the honeycomb briquette is moderate, carbon is fully combusted in the combustion holes, and simultaneously a large amount of heat is released, so that the temperature in the furnace is overhigh. Therefore, firstly, a large amount of heat in the furnace is dissipated through the furnace body; secondly, the burning time of the honeycomb briquette is shortened.

Disclosure of Invention

In order to overcome the defects of serious air pollution and coal energy waste of the existing civil honeycomb briquette, the utility model provides a civil briquette, which not only can greatly reduce the pollution, but also can make coal fully combusted, and improve the heat efficiency simultaneously, thereby achieving the purpose of energy conservation.

The utility model provides a technical scheme that its technical problem adopted is: the center of the civil briquette of the cylinder is provided with a central hole with larger diameter, and a plurality of combustion holes with smaller diameter are uniformly arranged around the central hole. When the civil coal ball is put into the coal stove to be ignited, the central hole mainly conveys sufficient hot air to the lower part of the bottom of the container to be burnt on the coal stove; the combustion hole has a small diameter, so that carbon on the inner wall of the combustion hole does not receive sufficient air to generate a large amount of carbon monoxide.

From the above equation of the heat of combustion for carbon and carbon monoxide: when carbon monoxide generated in the combustion hole rises to the bottom lower part of the container to be burned, the carbon monoxide is fully combusted by meeting with sufficient hot air to generate carbon dioxide, and simultaneously, a large amount of heat is released. Thus, firstly, the pollution of carbon monoxide is greatly reduced; secondly, the coal is fully combusted, and the heated container is just positioned on the outer flame of the fire, so that the heat efficiency is obviously improved, the utilization rate of the coal is improved, and the energy is saved; and thirdly, the temperature in the furnace is not too high due to the less heat released by the insufficient combustion of the carbon in the combustion holes and the cooling effect of the rising air in the central hole, so that the heat in the furnace is greatly reduced from being dissipated to the periphery through the furnace body, and the combustion time of the civil briquettes is prolonged. In addition, no matter the air inlet of the coal stove is opened or closed, the carbon monoxide generated can be fully combusted at the lower part of the bottom of the container to be combusted due to the arrangement of the central hole of the civil coal ball, namely the firepower of the coal stove can be adjusted.

The beneficial effects of the utility model are that, the air pollution that has significantly reduced during the use is showing simultaneously again and has practiced thrift limited coal resource. In addition, the fire power of the coal stove can be adjusted.
