Problems solved by technology
The oxygen supply and spontaneous combustion degree of the former are difficult to control, the amount of over-burning and under-burning is large, and the gas production is small and unstable
If the latter external heat source uses coal as fuel, it will still cause pollution, and the combustion temperature of coal is not high, so it is difficult to meet the needs of pyrolysis after transportation
If oil, electricity and other fuels are used, the gasification cost will be increased, and it cannot be used in large quantities
In addition, existing pyrolysis furnaces still have problems such as uneven heating of fuel and insufficient gasification, which limit the use of gasification technology

Embodiment Construction
[0047] The first embodiment: figure 1 A kind of sundry harmless separation furnace is introduced. The main features are: there are both direct combustion furnace 1 and pyrolysis furnace 6. One side of the direct combustion furnace 1 is provided with a fuel hopper 3 , and the other side is provided with a heat exhaust pipe 4 , and the other end of the heat exhaust pipe 4 is connected to a pyrolysis furnace 6 . One side of the pyrolysis furnace 6 is provided with a gas hopper 5, and the other side is provided with a collecting pipe 7. The direct combustion furnace directly burns the fuel, and the heat is input into the pyrolysis furnace, so that the fuel in the pyrolysis furnace is heated and gasified. The combustible gas is discharged through the collecting pipe 7, and can be fed into the gas furnace 9 for direct combustion and heat supply, and can also be stored as liquefied gas through the gas storage pipe 8 and the condensation compression device. In this way, various comp...

The invention relates to environment-friendly and energy-saving equipment, in particular to a clean combustion and pyrolysis furnace for fossil fuels. The clean combustion and pyrolysis furnace for the fossil fuels is characterized in that the furnace comprises a direct combustion furnace (1) and a pyrolysis furnace (6), wherein a fuel hopper (3) is arranged at one side of the direct combustion furnace (1), and a heat discharge tube (4) is arranged at the other side of the direct combustion furnace (1); the heat discharge tube (4) of the direct combustion furnace (1) is communicated with the pyrolysis furnace (6); and a gas hopper (5) is arranged at one side of the pyrolysis furnace (6), and a collection tube (7) is arranged at the other side of the pyrolysis furnace (6). The clean combustion and pyrolysis furnace for the fossil fuels has the following beneficial effects that by adopting a manner of heated air circulation, the direct combustion furnace is capable of accumulating heat, and achieving a quite high temperature even if fuels with low ignition points are utilized, adequate in combustion, extremely in emission, and capable of meeting the requirements of pyrolysis; the pyrolysis furnace is uniform in raw material distribution, consistent in heating, controllable in oxygen amount, adequate in gasification, free from harmful emission, and capable of not polluting the environment; and moreover, the clean combustion and pyrolysis furnace for the fossil fuels is simple in structure, low in cost, and quite considerable in application prospect.
Description
technical field [0001] The invention relates to an environment-friendly and energy-saving equipment, namely a fossil fuel clean combustion furnace. Background technique [0002] While coal and other fossil fuels provide us with energy, they also emit a large amount of pollutants, causing damage to the environment. Therefore, avoiding or reducing emissions, especially solving the problem of coal-burning emissions is a top priority. According to the existing technology, coal is pyrolyzed under anaerobic conditions and converted into combustible gas or liquid fuel, which can greatly reduce emissions when it is burned again. However, the existing coal gasification technology has various deficiencies, which limit its popularization and application. The existing coal gasification mainly adopts two methods, one is to control the entry of oxygen after the coal is ignited, and to crack and gasify under the condition of anoxic. The other is to use another heat source to decompose a...
