| description | The invention provides an automatic combustion control system for three kinds of coal gas of a coal gas power generation boiler, and relates to the technical field of coal gas power generation boilers. The first-stage desuperheating water and second-stage desuperheating water automatic regulation control module controls the output temperature information of the superheater; the boiler main steam pressure constant regulation control module regulates and controls the boiler main steam pressure, so that the boiler main steam pressure meets a preset requirement; the in-furnace gas quantity distribution regulation control module controls the in-furnace gas quantity; the hearth negative pressure automatic adjusting control module controls the rotating speed of the induced draft fan and controls the boiler hearth negative pressure amount, so that the boiler hearth negative pressure amount is within a preset threshold value. The field bus control technology and intelligent instrument decentralized control are utilize |
