Description

technical field [0001] The invention relates to the technical field of municipal sludge pyrolysis and gasification, in particular to an ignition control system and control method for a sludge combustible gas hot blast stove. Background technique [0002] Sludge is a solid sediment produced in the process of sewage treatment. The pollutants contained generally have a high calorific value, but due to the existence of a large amount of water, this part of the calorific value cannot be used. [0003] Sludge pyrolysis gasification technology is a technology that makes large-scale reduction, stabilization, harmlessness and resource utilization of sludge a reality under the premise of being odorless and pollution-free. Pyrolysis gasification technology has high thermal efficiency. Under high temperature and oxygen-poor conditions, organic matter is pyrolyzed into combustible gases such as carbon monoxide, hydrogen, and hydrocarbons. [0004] Due to the complexity of the sludge pyr...
