The combined type coal water slurry nozzle provided with the ignition device comprises an outer sprayer, a middle sprayer, an inner sprayer and a center pipe which are coaxially arranged, wherein an ignition cable is arranged on the outer wall of the center pipe, a hydrocyclone which can form rotary jet is arranged at the front end of the center pipe, an axial through hole is formed in the hydrocyclone, certain shrinkage is formed at the front end of the center pipe relative to the front end of the through hole of the hydrocyclone, part of or all the circumferential edge of the hydrocyclone is contacted with the inner cavity wall of the front end of the inner sprayer; certain retraction is formed in the front end face of the hydrocyclone relative to the end face reference surface of the inner sprayer, so that a premixing cavity B is formed. The combined type coal water slurry nozzle provided with the ignition device has the advantages that functions of an ignition nozzle and a technological nozzle in a gasifier are combined into one, so that the ignition nozzle and the technological nozzle can not be switched again and again in the whole gasification process, and complex operation in the gasification process is simplified; meanwhile, current required for ignition is small, so that the combustible effect on coal water slurry is improved, the ignition success rate is high, and the produced flame is stable.

The invention discloses an oil layer ignition method and device, a storage medium and a processor. The method comprises the steps that oil layer parameters of a to-be-ignited oil layer are acquired, wherein the oil layer parameters at least comprise the oil saturation of an oil layer, the ignition heat required for stable combustion of the to-be-ignited oil layer, the fuel deposition ratio corresponding to the ignition heat and a first corresponding relation used for representing the oil saturation of the oil layer and the fuel deposition ratio; a second corresponding relation used for representing the fuel deposition ratio and the heating rate of the oil layer is acquired; according to the first corresponding relation and the second corresponding relation, a third corresponding relation used for representing the oil saturation of the oil layer and the heating rate of the oil layer is determined; according to the third corresponding relation, it is determined that the heating rate of the oil layer corresponding to the oil saturation of the oil layer is ignition heating rate. The oil layer ignition method and device, the storage medium and the processor solve the technical problem that the ignition of the oil layer with the low oil saturation does not succeed easily.
