Description

technical field [0001] The invention relates to an internal heating dry distillation furnace. Background technique [0002] Oil shale is an ideal alternative energy source for oil and coal. With the increasing energy demand, energy supply and energy structure adjustment and other issues becoming more and more prominent, how to rationally develop and utilize oil shale resources and alleviate energy pressure has become an inevitable social and economic development. According to the trend, oil shale has three main uses. Not only can various oils be extracted, but also various synthetic fuel gases and chemical raw materials can be refined. The by-products can also be used to make bricks, cement and other building materials. China is one of the few countries in the world that has maintained shale oil production so far. Although oil shale in the world is abundant, widely used, and developed and utilized earlier, it has not been valued by most countries. At present, shale oil extr...
