Technical Field
The invention relates to combustion equipment, in particular to combustion equipment capable of treating tar in fuel gas.
Background
In the comprehensive gasification treatment of straw and similar processes, the produced combustible gas contains a certain amount of tar, and the tar is completely mixed with the combustible gas in a gaseous state in the state.
The tar is complex in components and difficult to treat, if tar is not treated, the tar is directly combusted, the tar cannot be decomposed, the tar is condensed into liquid state when being lower than 200 ℃ after being discharged, the liquid tar is in black thick liquid state and is easy to mix and gather with other ash and water, a subsequent air supply pipeline or a combustion tool is blocked, particles such as carbon black and the like can be generated when fine tar particles are combusted, the subsequent gas utilization equipment is greatly damaged, and black smoke is formed after the gas is discharged, so that pollution is caused.
The energy of tar accounts for about 10% of the total energy, and if the tar is directly discharged, the gasification efficiency of the comprehensive gasification treatment of the straw is reduced.
At present, the tar is treated in the following modes: physical separation method: firstly, converting tar from a gas state to a liquid state, separating the tar from the gas by a water washing or filtering method, and then treating the tar as waste, wherein the method wastes the energy of the tar on one hand, and the improper treatment of the tar can cause serious pollution to a catalytic cracking method on the other hand: after gasification, the combustible gas with tar enters a catalytic cracking device, at the moment, the temperature of the combustible gas with tar can be reduced to 600 ℃, an external heat source keeps the catalytic cracking device at 750 900 ℃, and the catalytic cracking of the tar reaches more than 99% under the action of a catalyst in the catalytic cracking device.
