Abstract

The invention relates to the technical field of low-rank coal medium-and low-temperature pyrolysis application and discloses a pyrolyzing furnace, a flame path of the pyrolyzing furnace and application of the pyrolyzing furnace. The flame path of the pyrolyzing furnace comprises a closed pipeline with two ends open, a flame nozzle with a fuel gas inlet is arranged on the front portion of the closed pipeline, the tail end of the closed pipeline is provided with a flue gas outlet, and a temperature regulation cold air inlet of a temperature regulation cold air branch pipe for input of temperature regulation cold is formed between the flame nozzle and the flue gas outlet. By the flame path of the pyrolyzing furnace, the temperature of flue gas entering a combustion chamber of the pyrolyzing furnace is lower than heat resistance temperature of a furnace body material, cost reduction can be realized, local high-temperature zones in the combustion chamber are avoided, and high pyrolysis uniformity can be achieved.

Description

Technical field [0001] The invention relates to the technical field of low-rank pyrolysis application of low-rank coal, in particular to a pyrolysis furnace, a pyrolysis furnace and its application. Background technique [0002] As a fossil energy resource, coal is the future development direction for its clean, efficient, comprehensive transformation and utilization. Poly-generation or cascade-based utilization of coal pyrolysis conforms to the principles of clean, high-efficiency, and comprehensive transformation and utilization, and has attracted the attention of researchers and developers. Coal pyrolysis, the main process unit, has received more attention. [0003] At present, pyrolysis furnaces are mainly divided into two types: internal heating and external heating, and neither internal heating nor external heating has a separately designed fire channel, and both types of pyrolysis furnaces use the combustion chamber as The fire channel is used, so it is impossible to pass c...
