Embodiment

[0045] Before the co-fired boiler starts to work, first confirm that the regulators of each layer of the burner are in the automatic adjustment mode, and set the boiler superheated steam pressure setting value and deviation high limit. After the boiler burner is working, the detection module detects the measured value of the superheated steam pressure of the boiler and transmits the measured value to the automatic control module. The value is compared with the set deviation high limit value and deviation low limit value, if the deviation value is greater than or equal to the preset deviation high limit value, the fuel load increase regulation is started. The operation process of fuel load increase adjustment is as follows: First, the automatic control module controls the valve module to input fuel in sequence according to the order of coke oven gas, upper blast furnace gas, lower blast furnace gas, upper layer pulverized coal, middle layer pulverized coal, and lower layer pulve...

Abstract

The invention discloses an automatic fuel adjustment system of a multi-fuel fired boiler, and belongs to the technical field of automatic control. The automatic fuel adjustment system solves the problems that in the prior art, due to the lower pressure of the coal gas of a pipeline, coal gas blasting is easily caused in an existing fuel adjustment system, quality of automatic fuel adjustment is poor, and the heat loss is large. The system comprises an automatic control module, a detection module and a valve module, wherein the automatic control module judges the burning state of the boiler according to the difference value between the overheating steam pressure measuring value detected by the detection module and the preset boiler overheating steam pressure setting value and transmits a corresponding command to the valve module, the detection module is used for detecting various parameters of boiler burning and transmitting the corresponding parameters to the automatic control module, the valve module receives the command from the automatic control module, adjusts fuel of a corresponding fuel layer, and can manually adjust valves in the modules, and the automatic control module is respectively connected with the detection module and the valve module. The invention further provides an automatic fuel adjustment method of the multi-fuel fired boiler. The automatic fuel adjustment system and method of the multi-fuel fired boiler are suitable for fuel adjustment of the multi-fuel fired boiler.

Description

technical field [0001] The invention belongs to the technical field of automatic control, in particular to automatic adjustment of boiler fuel. Background technique [0002] Co-fired boilers use blast furnace gas from ironmaking blast furnaces, coke oven gas from coke ovens, and pulverized coal as the main fuel for boilers. The four corners of the co-fired boiler body are respectively equipped with a burner. There are 4 burners in total. The burners are divided into 8 layers. powder, burning coke oven gas, and igniting coke oven gas. The adjustment of the two gas fuels of the co-fired boiler is realized through an explosion-proof regulating valve installed on the blast furnace gas or coke oven gas main pipe before entering the burners at the four corners. The adjustment is adjusted by the speed of the powder feeder that transports the pulverized coal. Since it is difficult to measure the pulverized coal that enters the furnace for combustion, the pulverized coal is basical...
