[0002] At present, in the petrochemical industry, coal chemical industry and other industries, a large amount of combustible flare gas that cannot be directly used and must be discharged will be generated when the production equipment is in the start-up and shutdown state, normal operation state, and accident states such as fire, power outage, and water outage. The composition of these flare gases is complex and the flow fluctuation range is large. Usually, elevated flares are used to directly burn them at high altitudes for treatment; when the heat of combustion is recovered, it is only a single method of driving steam turbines to generate electricity by heating water. This method is only suitable for uninterrupted and continuous flare combustion. However, flare combustion depends on whether there is combustible gas to be processed before use. It is very arbitrary and cannot provide heat source uninterruptedly, resulting in occasional power generation and garbage electricity. It is inconvenient to recycle and reuse, and frequent restarts can easily cause damage to power generation components. Therefore, it is urgent to propose a solar torch with waste heat recovery function. Summary of the invention
